NAME

       smartd.conf - SMART Disk Monitoring Daemon Configuration File

FULL PATH

       /etc/smartd.conf

PACKAGE VERSION

       smartmontools-5.41 2011-06-09 r3365

DESCRIPTION

       /etc/smartd.conf is the configuration file for the smartd daemon, which
       monitors the Self-Monitoring, Analysis and Reporting Technology (SMART)
       system built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives.

       If  the configuration file /etc/smartd.conf is present, smartd reads it
       at  startup,  before  fork(2)ing  into  the   background.   If   smartd
       subsequently   receives   a  HUP  signal,  it  will  then  re-read  the
       configuration file.  If smartd is running in debug mode,  then  an  INT
       signal  will  also  make it re-read the configuration file. This signal
       can be generated by typing <CONTROL-C> in  the  terminal  window  where
       smartd is running.

CONFIGURATION FILE /etc/smartd.conf

       In  the absence of a configuration file, under Linux smartd will try to
       open the 20 ATA devices /dev/hd[a-t] and the 26 SCSI devices /dev/sd[a-
       z].   Under  FreeBSD,  smartd will try to open all existing ATA devices
       (with entries in /dev) /dev/ad[0-9]+  and  all  existing  SCSI  devices
       (using  CAM  subsystem).  Under NetBSD/OpenBSD, smartd will try to open
       all existing ATA devices (with entries in /dev) /dev/wd[0-9]+c and  all
       existing SCSI devices /dev/sd[0-9]+c.  Under Solaris smartd will try to
       open  all  entries  "/dev/rdsk/c?t?d?s?"  for  IDE/ATA  and  SCSI  disk
       devices, and entries "/dev/rmt/*" for SCSI tape devices.  Under Windows
       smartd    will    try    to    open    all    entries    "/dev/hd[a-j]"
       ("\\.\PhysicalDrive[0-9]")   for  IDE/ATA  devices  on  WinNT4/2000/XP,
       "/dev/hd[a-d]" (bitmask from "\\.\SMARTVSD")  for  IDE/ATA  devices  on
       Win95/98/98SE/ME,  and "/dev/scsi[0-9][0-7]" (ASPI adapter 0-9, ID 0-7)
       for SCSI devices on all versions of Windows.  Under Darwin, smartd will
       open any ATA block storage device.

       This  can  be  annoying if you have an ATA or SCSI device that hangs or
       misbehaves when receiving SMART  commands.   Even  if  this  causes  no
       problems,  you may be annoyed by the string of error log messages about
       block-major devices that can't be found, and SCSI devices that can't be
       opened.

       One  can  avoid  this  problem, and gain more control over the types of
       events  monitored  by  smartd,  by   using   the   configuration   file
       /etc/smartd.conf.   This  file  contains  a list of devices to monitor,
       with one device per  line.   An  example  file  is  included  with  the
       smartmontools  distribution.  You  will  find this sample configuration
       file in /usr/share/doc/smartmontools/. For security, the  configuration
       file  should not be writable by anyone but root. The syntax of the file
       is as follows:

       o   There should be one device listed per line, although you  may  have
           lines that are entirely comments or white space.

       o   Any text following a hash sign '#' and up to the end of the line is
           taken to be a comment, and ignored.

       o   Lines may be continued by using a backslash '\' as  the  last  non-
           whitespace or non-comment item on a line.

       o   Note: a line whose first character is a hash sign '#' is treated as
           a white-space blank line, not as a non-existent line, and will  end
           a continuation line.

       Here  is an example configuration file.  It's for illustrative purposes
       only; please don't copy it onto your system without reading to the  end
       of the DIRECTIVES Section below!

CONFIGURATION FILE DIRECTIVES

       If  a  non-comment  entry  in the configuration file is the text string
       DEVICESCAN in capital letters, then smartd will  ignore  any  remaining
       lines in the configuration file, and will scan for devices.  DEVICESCAN
       may optionally be followed by Directives that will apply to all devices
       that are found in the scan.  Please see below for additional details.

       The  following  are the Directives that may appear following the device
       name or DEVICESCAN on any line of  the  /etc/smartd.conf  configuration
       file.  Note  that  these  are NOT command-line options for smartd.  The
       Directives below may appear in any order, following the device name.

       For an ATA device, if no Directives appear, then  the  device  will  be
       monitored  as  if the '-a' Directive (monitor all SMART properties) had
       been given.

       If a SCSI  disk  is  listed,  it  will  be  monitored  at  the  maximum
       implemented  level:  roughly  equivalent  to using the '-H -l selftest'
       options for an ATA disk.  So with the  exception  of  '-d',  '-m',  '-l
       selftest',  '-s',  and  '-M', the Directives below are ignored for SCSI
       disks.  For SCSI disks, the '-m' Directive sends a warning email if the
       SMART  status  indicates a disk failure or problem, if the SCSI inquiry
       about disk status fails, or if new errors appear in the self-test log.

       If a 3ware controller is used then the corresponding SCSI (/dev/sd?) or
       character  device  (/dev/twe?,  /dev/twa? or /dev/twl?) must be listed,
       along with the '-d 3ware,N' Directive (see below).  The individual  ATA
       disks  hosted  by  the  3ware controller appear to smartd as normal ATA
       devices.  Hence all the ATA directives can be used for these disks (but
       see note below).

       If  an  Areca  controller  is  used then the corresponding SCSI generic
       device  (/dev/sg?)   must  be  listed,  along  with  the  '-d  areca,N'
       Directive  (see  below).  The individual SATA disks hosted by the Areca
       controller appear to smartd as normal ATA devices.  Hence all  the  ATA
       directives can be used for these disks.  Areca firmware version 1.46 or
       later which  supports  smartmontools  must  be  used;  Please  see  the
       smartctl(8) man page for further details.

       -d TYPE
              Specifies  the  type of the device.  The valid arguments to this
              directive are:

              auto - attempt to guess the device type from the device name  or
              from  controller  type  info provided by the operating system or
              from a matching USB ID entry in the drive database.  This is the
              default.

              ata - the device type is ATA.  This prevents smartd from issuing
              SCSI commands to an ATA device.

              scsi - the device type  is  SCSI.   This  prevents  smartd  from
              issuing ATA commands to a SCSI device.

              sat - the device type is SCSI to ATA Translation (SAT).  This is
              for ATA disks that have a SCSI to ATA  Translation  (SAT)  Layer
              (SATL)  between  the disk and the operating system.  SAT defines
              two ATA PASS THROUGH SCSI commands, one 12 bytes  long  and  the
              other  16  bytes long.  The default is the 16 byte variant which
              can be overridden with either '-d sat,12' or '-d sat,16'.

              usbcypress - this device type is for ATA disks that are behind a
              Cypress USB to PATA bridge.  This will use the ATACB proprietary
              scsi pass through command.  The default SCSI operation  code  is
              0x24,   but   although   it   can   be   overridden   with   '-d
              usbcypress,0xN', where N is  the  scsi  operation  code,  you're
              running the risk of damage to the device or filesystems on it.

              usbjmicron  - this device type is for SATA disks that are behind
              a JMicron USB to PATA/SATA  bridge.   The  48-bit  ATA  commands
              (required  e.g. for '-l xerror', see below) do not work with all
              of these bridges and are therefore disabled by  default.   These
              commands  can be enabled by '-d usbjmicron,x'.  If two disks are
              connected to a bridge  with  two  ports,  an  error  message  is
              printed  if  no PORT is specified.  The port can be specified by
              '-d usbjmicron[,x],PORT' where PORT is 0 (master) or 1  (slave).
              This  is  not  necessary if the device uses a port multiplier to
              connect multiple disks to one  port.   The  disks  appear  under
              separate  /dev/ice  names  then.  CAUTION: Specifying ',x' for a
              device which does not support it results in I/O errors  and  may
              disconnect  the  drive.   The same applies if the specified PORT
              does not exist or is not connected to a disk.

              usbsunplus - this device type is for SATA disks that are  behind
              a SunplusIT USB to SATA bridge.

              marvell  -  [Linux only] interact with SATA disks behind Marvell
              chip-set controllers  (using  the  Marvell  rather  than  libata
              driver).

              megaraid,N  -  [Linux  only]  the device consists of one or more
              SCSI/SAS disks connected to a  MegaRAID  controller.   The  non-
              negative  integer N (in the range of 0 to 127 inclusive) denotes
              which disk on the controller is monitored.  This interface  will
              also  work  for  Dell  PERC controllers.  In log files and email
              messages this disk will be identified as megaraid_disk_XXX  with
              XXX  in  the  range  from  000 to 127 inclusive.  Please see the
              smartctl(8) man page for further details.

              3ware,N - [FreeBSD and Linux only] the device consists of one or
              more  ATA  disks connected to a 3ware RAID controller.  The non-
              negative integer N (in  the  range  from  0  to  127  inclusive)
              denotes which disk on the controller is monitored.  In log files
              and  email  messages   this   disk   will   be   identified   as
              3ware_disk_XXX with XXX in the range from 000 to 127 inclusive.

              Note  that  while  you  may  use  any  of the 3ware SCSI logical
              devices /dev/tw* to address any of  the  physical  disks  (3ware
              ports),  error  and log messages will make the most sense if you
              always list the 3ware SCSI logical device corresponding  to  the
              particular  physical disks.  Please see the smartctl(8) man page
              for further details.

              areca,N - [Linux only] the device consists of one or  more  SATA
              disks  connected to an Areca SATA RAID controller.  The positive
              integer N (in the range from 1 to 24  inclusive)  denotes  which
              disk  on  the  controller  is monitored.  In log files and email
              messages this disk will be identifed as areca_disk_XX with XX in
              the  range  from 01 to 24 inclusive.  Please see the smartctl(8)
              man page for further details.

              cciss,N - [FreeBSD and Linux only] the device consists of one or
              more  SCSI/SAS  disks connected to a cciss RAID controller.  The
              non-negative integer N (in the range from  0  to  15  inclusive)
              denotes which disk on the controller is monitored.  In log files
              and email messages this disk will be identified as cciss_disk_XX
              with  XX  in  the range from 00 to 15 inclusive.  Please see the
              smartctl(8) man page for further details.

              hpt,L/M/N - [FreeBSD and Linux only] the device consists of  one
              or   more   ATA   disks  connected  to  a  HighPoint  RocketRAID
              controller.  The integer L is the controller id, the  integer  M
              is the channel number, and the integer N is the PMPort number if
              it is available.  The allowed values  of  L  are  from  1  to  4
              inclusive,  M  are  from  1  to 8 inclusive and N from 1 to 4 if
              PMPort available.  And also these  values  are  limited  by  the
              model  of the HighPoint RocketRAID controller.  In log files and
              email messages this disk will be  identified  as  hpt_X/X/X  and
              X/X/X is the same as L/M/N, note if no N indicated, N set to the
              default value 1.   Please  see  the  smartctl(8)  man  page  for
              further details.

              removable  -  the  device  or  its  media  is  removable.   This
              indicates to smartd that it should continue (instead of exiting,
              which  is the default behavior) if the device does not appear to
              be present when smartd is started.  This Directive may  be  used
              in conjunction with the other '-d' Directives.

       -n POWERMODE[,N][,q]
              [ATA  only]  This  'nocheck' Directive is used to prevent a disk
              from being spun-up when it is periodically polled by smartd.

              ATA  disks  have  five  different  power  states.  In  order  of
              increasing   power   consumption   they   are:  'OFF',  'SLEEP',
              'STANDBY', 'IDLE', and 'ACTIVE'.  Typically in the  OFF,  SLEEP,
              and  STANDBY  modes  the  disk's  platters are not spinning. But
              usually, in response to SMART commands  issued  by  smartd,  the
              disk  platters are spun up.  So if this option is not used, then
              a disk which is in a low-power mode may be spun up and put  into
              a higher-power mode when it is periodically polled by smartd.

              Note  that  if the disk is in SLEEP mode when smartd is started,
              then it won't respond to smartd commands, and so the disk  won't
              be registered as a device for smartd to monitor. If a disk is in
              any other low-power mode, then the commands issued by smartd  to
              register the disk will probably cause it to spin-up.

              The  '-n'  (nocheck)  Directive  specifies  if smartd's periodic
              checks should still be carried out  when  the  device  is  in  a
              low-power  mode.   It  may  be used to prevent a disk from being
              spun-up by periodic  smartd  polling.   The  allowed  values  of
              POWERMODE are:

              never  -  smartd  will poll (check) the device regardless of its
              power mode. This may cause a  disk  which  is  spun-down  to  be
              spun-up  when smartd checks it.  This is the default behavior if
              the '-n' Directive is not given.

              sleep - check the device unless it is in SLEEP mode.

              standby - check the device unless it  is  in  SLEEP  or  STANDBY
              mode.   In  these  modes  most disks are not spinning, so if you
              want to prevent a laptop disk from spinning up  each  time  that
              smartd polls, this is probably what you want.

              idle  -  check the device unless it is in SLEEP, STANDBY or IDLE
              mode.  In the IDLE state, most disks are still spinning, so this
              is probably not what you want.

              Maximum  number of skipped checks (in a row) can be specified by
              appending  positive  number  ',N'   to   POWERMODE   (like   '-n
              standby,15').  After N checks are skipped in a row, powermode is
              ignored and the check is performed anyway.

              When a periodic test  is  skipped,  smartd  normally  writes  an
              informal log message. The message can be suppressed by appending
              the option  ',q'  to  POWERMODE  (like  '-n  standby,q').   This
              prevents a laptop disk from spinning up due to this message.

              Both ',N' and ',q' can be specified together.

       -T TYPE
              Specifies  how  tolerant  smartd  should  be  of  SMART  command
              failures.  The valid arguments to this Directive are:

              normal - do not try to monitor the disk  if  a  mandatory  SMART
              command  fails, but continue if an optional SMART command fails.
              This is the default.

              permissive - try to monitor the disk even if it appears to  lack
              SMART  capabilities.   This  may  be required for some old disks
              (prior to ATA-3 revision 4) that implemented  SMART  before  the
              SMART   standards   were   incorporated   into   the   ATA/ATAPI
              Specifications.  This may also be needed for some  Maxtor  disks
              which  fail  to  comply  with  the  ATA Specifications and don't
              properly indicate support for error- or self-test logging.

              [Please see the smartctl -T command-line option.]

       -o VALUE
              [ATA only] Enables or disables SMART Automatic  Offline  Testing
              when  smartd  starts  up  and  has no further effect.  The valid
              arguments to this Directive are on and off.

              The delay between tests is  vendor-specific,  but  is  typically
              four hours.

              Note that SMART Automatic Offline Testing is not part of the ATA
              Specification.  Please see the smartctl -o  command-line  option
              documentation for further information about this feature.

       -S VALUE
              Enables or disables Attribute Autosave when smartd starts up and
              has no further effect.  The valid arguments  to  this  Directive
              are  on  and  off.   Also affects SCSI devices.  [Please see the
              smartctl -S command-line option.]

       -H     [ATA only] Check the SMART health status of the  disk.   If  any
              Prefailure  Attributes are less than or equal to their threshold
              values, then disk failure is predicted in less  than  24  hours,
              and  a  message at loglevel 'LOG_CRIT' will be logged to syslog.
              [Please see the smartctl -H command-line option.]

       -l TYPE
              Reports increases in the number of errors in one of three  SMART
              logs.  The valid arguments to this Directive are:

              error  -  [ATA only] report if the number of ATA errors reported
              in the Summary SMART error log  has  increased  since  the  last
              check.

              xerror  - [ATA only] [NEW EXPERIMENTAL SMARTD FEATURE] report if
              the number of ATA errors reported in the Extended  Comprehensive
              SMART error log has increased since the last check.

              If  both '-l error' and '-l xerror' are specified, smartd checks
              the maximum of both values.

              [Please see the smartctl -l xerror command-line option.]

              selftest - report if the number of failed tests reported in  the
              SMART  Self-Test  Log  has increased since the last check, or if
              the timestamp associated with the most recent  failed  test  has
              increased.  Note that such errors will only be logged if you run
              self-tests on the disk (and it fails a test!).   Self-Tests  can
              be  run  automatically  by smartd: please see the '-s' Directive
              below.  Self-Tests  can  also  be  run  manually  by  using  the
              '-t short'  and '-t long' options of smartctl and the results of
              the testing can be observed  using  the  smartctl  '-l selftest'
              command-line  option.   [Please  see  the  smartctl  -l  and  -t
              command-line options.]

              [ATA only] Failed self-tests  outdated  by  a  newer  successful
              extended self-test are ignored.

              scterc,READTIME,WRITETIME  - [ATA only] [NEW EXPERIMENTAL SMARTD
              FEATURE] sets the SCT Error Recovery  Control  settings  to  the
              specified  values (deciseconds) when smartd starts up and has no
              further effect.  Values of 0 disable the feature,  other  values
              less   than   65   are   probably   not   supported.   For  RAID
              configurations, this is  typically  set  to  70,70  deciseconds.
              [Please see the smartctl -l scterc command-line option.]

       -s REGEXP
              Run  Self-Tests  or Offline Immediate Tests, at scheduled times.
              A Self- or Offline Immediate Test will be  run  at  the  end  of
              periodic  device  polling,  if  all  12 characters of the string
              T/MM/DD/d/HH match the extended regular expression REGEXP. Here:

              T   is the type of the test.  The values that smartd will try to
                  match  (in  turn)  are:  'L' for a Long Self-Test, 'S' for a
                  Short Self-Test, 'C' for a Conveyance Self-Test (ATA  only),
                  and  'O'  for an Offline Immediate Test (ATA only).  As soon
                  as a match is  found,  the  test  will  be  started  and  no
                  additional  matches  will be sought for that device and that
                  polling cycle.

                  To run scheduled Selective  Self-Tests,  use  'n'  for  next
                  span,  'r'  to  redo last span, or 'c' to continue with next
                  span or redo last span based on status of  last  test.   The
                  LBA  range  is  based  on the first span from the last test.
                  See the  smartctl  -t  select,[next|redo|cont]  options  for
                  further info.

                  [NEW  EXPERIMENTAL  SMARTD  FEATURE] Some disks (e.g. WD) do
                  not preserve the  selective  self  test  log  accross  power
                  cycles.   If state persistence ('-s' option) is enabled, the
                  last test span is preserved by smartd and used if (and  only
                  if) the selective self test log is empty.

              MM  is the month of the year, expressed with two decimal digits.
                  The range is from 01 (January) to 12  (December)  inclusive.
                  Do  not  use a single decimal digit or the match will always
                  fail!

              DD  is the day of the month, expressed with two decimal  digits.
                  The  range  is from 01 to 31 inclusive.  Do not use a single
                  decimal digit or the match will always fail!

              d   is the day of the week, expressed with  one  decimal  digit.
                  The range is from 1 (Monday) to 7 (Sunday) inclusive.

              HH  is the hour of the day, written with two decimal digits, and
                  given in hours after midnight.  The range is 00 (midnight to
                  just  before  1am)  to  23  (11pm  to  just before midnight)
                  inclusive.  Do not use a single decimal digit or  the  match
                  will always fail!

              Some  examples  follow.   In reading these, keep in mind that in
              extended regular  expressions  a  dot  '.'  matches  any  single
              character,  and  a  parenthetical  expression  such as '(A|B|C)'
              denotes any one of the three possibilities A, B, or C.

              To schedule a short Self-Test between 2-3am every morning, use:
               -s S/../.././02
              To schedule a long Self-Test between 4-5am every Sunday morning,
              use:
               -s L/../../7/04
              To  schedule  a  long Self-Test between 10-11pm on the first and
              fifteenth day of each month, use:
               -s L/../(01|15)/./22
              To schedule an Offline Immediate test after every midnight, 6am,
              noon,and  6pm,  plus a Short Self-Test daily at 1-2am and a Long
              Self-Test every Saturday at 3-4am, use:
               -s (O/../.././(00|06|12|18)|S/../.././01|L/../../6/03)
              If Long Self-Tests of a large disks take longer than the  system
              uptime,  a  full disk test can be performed by several Selective
              Self-Tests.  To setup a full test of a 1TB disk within  20  days
              (one 50GB span each day), run this command once:
                smartctl -t select,0-99999999 /dev/sda
              To run the next test spans on Monday-Friday between 12-13am, run
              smartd with this directive:
               -s n/../../[1-5]/12

              Scheduled tests are run  immediately  following  the  regularly-
              scheduled  device  polling, if the current local date, time, and
              test type, match REGEXP.   By  default  the  regularly-scheduled
              device  polling  occurs  every  thirty  minutes  after  starting
              smartd.  Take caution if you use the '-i' option  to  make  this
              polling  interval  more  than  sixty minutes: the poll times may
              fail to coincide with any of the testing  times  that  you  have
              specified  with  REGEXP.   In  this  case  the  test will be run
              following the next device polling.

              Before running an offline or self-test, smartd checks to be sure
              that  a  self-test  is  not  already running.  If a self-test is
              already running,  then  this  running  self  test  will  not  be
              interrupted to begin another test.

              smartd  will not attempt to run any type of test if another test
              was already started or run in the same hour.

              To avoid performance problems during system  boot,  smartd  will
              not  attempt to run any scheduled tests following the very first
              device polling (unless '-q onecheck' is specified).

              Each time a test is run, smartd will log  an  entry  to  SYSLOG.
              You  can  use these or the '-q showtests' command-line option to
              verify that you  constructed  REGEXP  correctly.   The  matching
              order  (L  before  S before C before O) ensures that if multiple
              test types are all scheduled for the same hour, the longer  test
              type has precedence.  This is usually the desired behavior.

              If  the  scheduled  tests  are  used  in  conjunction with state
              persistence ('-s' option), smartd will also  try  to  match  the
              hours  since  last  shutdown  (or  90 days at most). If any test
              would have been started during downtime, the longest (see above)
              of these tests is run after second device polling.

              If  the  '-n'  directive  is  used  and any test would have been
              started during disk standby time, the longest of these tests  is
              run when the disk is active again.

              Unix  users:  please  beware that the rules for extended regular
              expressions [regex(7)]  are  not  the  same  as  the  rules  for
              file-name  pattern matching by the shell [glob(7)].  smartd will
              issue harmless informational  warning  messages  if  it  detects
              characters  in REGEXP that appear to indicate that you have made
              this mistake.

       -m ADD Send a warning email to the email address ADD if the '-H', '-l',
              '-f',  '-C', or '-O' Directives detect a failure or a new error,
              or if a SMART command to the disk  fails.  This  Directive  only
              works  in  conjunction  with these other Directives (or with the
              equivalent default '-a' Directive).

              To prevent your email in-box from getting filled up with warning
              messages, by default only a single warning will be sent for each
              of the enabled alert types, '-H', '-l', '-f', '-C', or '-O' even
              if  more than one failure or error is detected or if the failure
              or error persists.  [This behavior can be modified; see the '-M'
              Directive below.]

              To  send  email  to more than one user, please use the following
              "comma      separated"      form      for      the      address:
              user1@add1,user2@add2,...,userN@addN (with no spaces).

              To  test  that  email is being sent correctly, use the '-M test'
              Directive described below to send  one  test  email  message  on
              smartd startup.

              By  default,  email  is  sent using the system mail command.  In
              order that smartd find the mail command (normally /bin/mail)  an
              executable  named  'mail'  must  be  in the path of the shell or
              environment from which smartd  was  started.   If  you  wish  to
              specify  an  explicit  path  to the mail executable (for example
              /usr/local/bin/mail) or a custom script to run, please  use  the
              '-M exec' Directive below.

              Note  that  by default under Solaris, in the previous paragraph,
              'mailx' and '/bin/mailx' are  used,  since  Solaris  '/bin/mail'
              does not accept a '-s' (Subject) command-line argument.

              On  Windows, the 'Blat' mailer (http://blat.sourceforge.net/) is
              used by default.  This mailer  uses  a  different  command  line
              syntax, see '-M exec' below.

              Note  also that there is a special argument <nomailer> which can
              be given to the '-m' Directive in conjunction with the '-M exec'
              Directive. Please see below for an explanation of its effect.

              If the mailer or the shell running it produces any STDERR/STDOUT
              output, then a snippet of that output will be copied to  SYSLOG.
              The  remainder  of  the  output  is  discarded.  If problems are
              encountered in sending mail, this should help you to  understand
              and  fix  them.  If you have mail problems, we recommend running
              smartd in debug mode with the '-d' flag,  using  the  '-M  test'
              Directive described below.

              The  following  extension is available on Windows: By specifying
              'msgbox' as a mail address, a warning "email" is displayed as  a
              message box on the screen.  Using both 'msgbox' and regular mail
              addresses is possible, if 'msgbox' is  the  first  word  in  the
              comma  separated list.  With 'sysmsgbox', a system modal (always
              on top) message box is used. If running as a service, a  service
              notification  message  box  (always  shown  on  current  visible
              desktop) is used.

       -M TYPE
              These  Directives  modify  the  behavior  of  the  smartd  email
              warnings  enabled with the '-m' email Directive described above.
              These '-M' Directives only work in  conjunction  with  the  '-m'
              Directive and can not be used without it.

              Multiple  -M  Directives  may be given.  If more than one of the
              following three -M Directives are given  (example:  -M  once  -M
              daily) then the final one (in the example, -M daily) is used.

              The  valid  arguments  to  the  -M  Directive  are  (one  of the
              following three):

              once - send only one warning email for each type of disk problem
              detected.   This  is  the default unless state persistence ('-s'
              option) is enabled.

              daily - send additional warning reminder emails, once  per  day,
              for  each type of disk problem detected.  This is the default if
              state persistence ('-s' option) is enabled.

              diminishing - send additional warning reminder emails,  after  a
              one-day  interval,  then  a  two-day  interval,  then a four-day
              interval, and so on for each type of disk problem detected. Each
              interval is twice as long as the previous interval.

              In  addition,  one  may  add  zero  or  more  of  the  following
              Directives:

              test - send a single test email immediately upon smartd startup.
              This  allows  one  to  verify that email is delivered correctly.
              Note that if this Directive is used, smartd will also  send  the
              normal email warnings that were enabled with the '-m' Directive,
              in addition to the single test email!

              exec PATH - run the executable PATH instead of the default  mail
              command, when smartd needs to send email.  PATH must point to an
              executable binary file or script.

              By setting PATH to point to a customized script,  you  can  make
              smartd  perform  useful  tricks  when a disk problem is detected
              (beeping the console, shutting down  the  machine,  broadcasting
              warnings  to  all logged-in users, etc.)  But please be careful.
              smartd will block until the executable PATH returns, so if  your
              executable  hangs,  then  smartd  will  also  hang.  Some sample
              scripts are included in /usr/share/doc/smartmontools/examples//.

              The return status of the executable is  recorded  by  smartd  in
              SYSLOG.  The  executable  is  not expected to write to STDOUT or
              STDERR.  If it does, then this is interpreted as indicating that
              something is going wrong with your executable, and a fragment of
              this output is logged to SYSLOG to help you  to  understand  the
              problem.  Normally, if you wish to leave some record behind, the
              executable should send mail or write to a file or device.

              Before  running  the  executable,  smartd  sets  a   number   of
              environment  variables.  These environment variables may be used
              to control the executable's behavior.  The environment variables
              exported by smartd are:

              SMARTD_MAILER
                  is  set  to  the  argument of -M exec, if present or else to
                  'mail' (examples: /bin/mail, mail).

              SMARTD_DEVICE
                  is set to the device path (examples: /dev/hda, /dev/sdb).

              SMARTD_DEVICETYPE
                  is set to the device type specified  by  '-d'  directive  or
                  'auto' if none.

              SMARTD_DEVICESTRING
                  is  set to the device description.  For SMARTD_DEVICETYPE of
                  ata or scsi, this is the same as SMARTD_DEVICE.   For  3ware
                  RAID    controllers,    the    form    used   is   '/dev/sdc
                  [3ware_disk_01]'.  For HighPoint RocketRAID controller,  the
                  form  is  '/dev/sdd  [hpt_1/1/1]' under Linux or '/dev/hptrr
                  [hpt_1/1/1]' under FreeBSD.  For Areca controllers, the form
                  is  '/dev/sg2  [areca_disk_09]'.   In these cases the device
                  string contains a space  and  is  NOT  quoted.   So  to  use
                  $SMARTD_DEVICESTRING  in  a  bash script you should probably
                  enclose it in double quotes.

              SMARTD_FAILTYPE
                  gives the reason for the  warning  or  message  email.   The
                  possible values that it takes and their meanings are:
                  EmailTest: this is an email test message.
                  Health: the SMART health status indicates imminent failure.
                  Usage: a usage Attribute has failed.
                  SelfTest: the number of self-test failures has increased.
                  ErrorCount:  the  number  of errors in the ATA error log has
                  increased.
                  CurrentPendingSector: one of more disk sectors could not  be
                  read  and  are marked to be reallocated (replaced with spare
                  sectors).
                  OfflineUncorrectableSector:  during  off-line  testing,   or
                  self-testing, one or more disk sectors could not be read.
                  Temperature:  Temperature  reached  critical  limit  (see -W
                  directive).
                  FailedHealthCheck: the SMART health status command failed.
                  FailedReadSmartData: the command  to  read  SMART  Attribute
                  data failed.
                  FailedReadSmartErrorLog: the command to read the SMART error
                  log failed.
                  FailedReadSmartSelfTestLog: the command to  read  the  SMART
                  self-test log failed.
                  FailedOpenDevice: the open() command to the device failed.

              SMARTD_ADDRESS
                  is  determined  by  the  address  argument  ADD  of the '-m'
                  Directive.  If ADD is <nomailer>, then SMARTD_ADDRESS is not
                  set.   Otherwise,  it  is set to the comma-separated-list of
                  email addresses given by the argument ADD, with  the  commas
                  replaced  by  spaces  (example:admin@example.com  root).  If
                  more than one email address is given, then this string  will
                  contain  space characters and is NOT quoted, so to use it in
                  a bash script you may want to enclose it in double quotes.

              SMARTD_MESSAGE
                  is set to the one sentence  summary  warning  email  message
                  string  from  smartd.   This  message  string contains space
                  characters and is NOT quoted. So to use $SMARTD_MESSAGE in a
                  bash script you should probably enclose it in double quotes.

              SMARTD_FULLMESSAGE
                  is  set  to the contents of the entire email warning message
                  string from smartd.  This message string contains space  and
                  return   characters   and   is   NOT   quoted.   So  to  use
                  $SMARTD_FULLMESSAGE in a bash  script  you  should  probably
                  enclose it in double quotes.

              SMARTD_TFIRST
                  is a text string giving the time and date at which the first
                  problem of this type was reported. This text string contains
                  space  characters  and  no  newlines, and is NOT quoted. For
                  example:
                  Sun Feb  9 14:58:19 2003 CST

              SMARTD_TFIRSTEPOCH
                  is an integer, which is the unix epoch  (number  of  seconds
                  since Jan 1, 1970) for SMARTD_TFIRST.

              The  shell  which  is  used to run PATH is system-dependent. For
              vanilla Linux/glibc it's bash. For other systems, the  man  page
              for popen(3) should say what shell is used.

              If  the  '-m  ADD'  Directive  is  given  with  a normal address
              argument, then the executable pointed to by PATH will be run  in
              a  shell with STDIN receiving the body of the email message, and
              with the same command-line arguments:
              -s "$SMARTD_SUBJECT" $SMARTD_ADDRESS
              that would normally be provided to 'mail'.  Examples include:
              -m user@home -M exec /bin/mail
              -m admin@work -M exec /usr/local/bin/mailto
              -m root -M exec /Example_1/bash/script/below

              Note that on Windows, the syntax of the 'Blat' mailer is used:
              - -q -subject "$SMARTD_SUBJECT" -to "$SMARTD_ADDRESS"

              If the '-m ADD' Directive is  given  with  the  special  address
              argument  <nomailer>  then  the executable pointed to by PATH is
              run in a shell with no STDIN and no command-line arguments,  for
              example:
              -m <nomailer> -M exec /Example_2/bash/script/below
              If the executable produces any STDERR/STDOUT output, then smartd
              assumes that something is going wrong, and  a  snippet  of  that
              output will be copied to SYSLOG.  The remainder of the output is
              then discarded.

              Some EXAMPLES of scripts that can be used  with  the  '-M  exec'
              Directive are given below. Some sample scripts are also included
              in /usr/share/doc/smartmontools/examples//.

       -f     [ATA only] Check for 'failure'  of  any  Usage  Attributes.   If
              these  Attributes  are  less  than or equal to the threshold, it
              does NOT indicate  imminent  disk  failure.   It  "indicates  an
              advisory  condition  where  the  usage  or age of the device has
              exceeded its intended design  life  period."   [Please  see  the
              smartctl -A command-line option.]

       -p     [ATA  only]  Report anytime that a Prefail Attribute has changed
              its value since the last check, 30 minutes ago. [Please see  the
              smartctl -A command-line option.]

       -u     [ATA only] Report anytime that a Usage Attribute has changed its
              value since the last check, 30  minutes  ago.  [Please  see  the
              smartctl -A command-line option.]

       -t     [ATA  only] Equivalent to turning on the two previous flags '-p'
              and  '-u'.   Tracks  changes  in  all  device  Attributes  (both
              Prefailure  and Usage). [Please see the smartctl -A command-line
              option.]

       -i ID  [ATA only] Ignore device Attribute number ID when  checking  for
              failure  of  Usage  Attributes.  ID must be a decimal integer in
              the range from 1 to 255.  This Directive modifies  the  behavior
              of the '-f' Directive and has no effect without it.

              This  is  useful,  for  example, if you have a very old disk and
              don't want to keep getting messages about the  hours-on-lifetime
              Attribute  (usually  Attribute  9)  failing.  This Directive may
              appear multiple times for a single device, if you want to ignore
              multiple Attributes.

       -I ID  [ATA  only]  Ignore device Attribute ID when tracking changes in
              the Attribute values.  ID must be a decimal integer in the range
              from  1  to  255.   This  Directive modifies the behavior of the
              '-p', '-u', and '-t'  tracking  Directives  and  has  no  effect
              without one of them.

              This  is useful, for example, if one of the device Attributes is
              the disk  temperature  (usually  Attribute  194  or  231).  It's
              annoying to get reports each time the temperature changes.  This
              Directive may appear multiple times for a single device, if  you
              want to ignore multiple Attributes.

       -r ID[!]
              [ATA  only]  When tracking, report the Raw value of Attribute ID
              along with its (normally reported) Normalized value.  ID must be
              a  decimal  integer  in the range from 1 to 255.  This Directive
              modifies the behavior of  the  '-p',  '-u',  and  '-t'  tracking
              Directives  and  has  no  effect  without  one  of  them.   This
              Directive may be given multiple times.

              A  common  use  of  this  Directive  is  to  track  the   device
              Temperature (often ID=194 or 231).

              If the optional flag '!' is appended, a change of the Normalized
              value is considered critical.  The  report  will  be  logged  as
              LOG_CRIT and a warning email will be sent if '-m' is specified.

       -R ID[!]
              [ATA  only]  When  tracking,  report  whenever  the Raw value of
              Attribute ID  changes.   (Normally  smartd  only  tracks/reports
              changes  of  the  Normalized  Attribute  values.)   ID must be a
              decimal integer in the range from  1  to  255.   This  Directive
              modifies  the  behavior  of  the  '-p',  '-u', and '-t' tracking
              Directives  and  has  no  effect  without  one  of  them.   This
              Directive may be given multiple times.

              If  this  Directive  is given, it automatically implies the '-r'
              Directive for the same Attribute, so that the Raw value  of  the
              Attribute is reported.

              A   common  use  of  this  Directive  is  to  track  the  device
              Temperature (often ID=194  or  231).   It  is  also  useful  for
              understanding how different types of system behavior affects the
              values of certain Attributes.

              If the optional flag '!' is appended, a change of the Raw  value
              is  considered  critical.  The report will be logged as LOG_CRIT
              and a warning email will be  sent  if  '-m'  is  specified.   An
              example is '-R 5!' to warn when new sectors are reallocated.

       -C ID[+]
              [ATA  only]  Report  if the current number of pending sectors is
              non-zero.  Here ID is the id number of the Attribute  whose  raw
              value is the Current Pending Sector count.  The allowed range of
              ID is 0 to 255 inclusive.   To  turn  off  this  reporting,  use
              ID = 0.   If  the -C ID option is not given, then it defaults to
              -C 197 (since Attribute 197 is generally used to monitor pending
              sectors).   If  the  name  of this Attribute is changed by a '-v
              197,FORMAT,NAME' directive, the default is changed to -C 0.

              If '+' is specified, a report is only printed if the  number  of
              sectors  has  increased  between two check cycles. Some disks do
              not reset this attribute when a bad sector is reallocated.   See
              also '-v 197,increasing' below.

              A  pending sector is a disk sector (containing 512 bytes of your
              data) which  the  device  would  like  to  mark  as  ``bad"  and
              reallocate.   Typically  this  is because your computer tried to
              read that sector, and the read failed because the data on it has
              been   corrupted   and   has  inconsistent  Error  Checking  and
              Correction (ECC) codes.  This is important to know,  because  it
              means  that  there  is  some  unreadable  data on the disk.  The
              problem of figuring out  what  file  this  data  belongs  to  is
              operating  system  and  file system specific.  You can typically
              force the sector to reallocate by writing  to  it  (translation:
              make  the device substitute a spare good sector for the bad one)
              but at the price of losing the 512 bytes of data stored there.

       -U ID[+]
              [ATA only] Report if the number of offline uncorrectable sectors
              is  non-zero.   Here  ID is the id number of the Attribute whose
              raw value  is  the  Offline  Uncorrectable  Sector  count.   The
              allowed  range  of  ID  is 0 to 255 inclusive.  To turn off this
              reporting, use ID = 0.  If the -U ID option is not  given,  then
              it  defaults to -U 198 (since Attribute 198 is generally used to
              monitor offline uncorrectable sectors).  If  the  name  of  this
              Attribute  is  changed  by  a  '-v  198,FORMAT,NAME' (except '-v
              198,FORMAT,Offline_Scan_UNC_SectCt'), directive, the default  is
              changed to -U 0.

              If  '+'  is specified, a report is only printed if the number of
              sectors has increased since the last check cycle. Some disks  do
              not  reset this attribute when a bad sector is reallocated.  See
              also '-v 198,increasing' below.

              An offline uncorrectable sector is a disk sector which  was  not
              readable  during  an  off-line  scan  or  a  self-test.  This is
              important to know, because if you have data stored in this  disk
              sector, and you need to read it, the read will fail.  Please see
              the previous '-C' option for more details.

       -W DIFF[,INFO[,CRIT]]
              Report if the current temperature had changed by at  least  DIFF
              degrees  since  last report, or if new min or max temperature is
              detected.  Report or Warn if the temperature is greater or equal
              than  one of INFO or CRIT degrees Celsius.  If the limit CRIT is
              reached, a message with loglevel 'LOG_CRIT' will  be  logged  to
              syslog and a warning email will be send if '-m' is specified. If
              only  the  limit  INFO  is  reached,  a  message  with  loglevel
              'LOG_INFO' will be logged.

              If  this directive is used in conjunction with state persistence
              ('-s' option), the min and max temperature values are  preserved
              across boot cycles. The minimum temperature value is not updated
              during the first 30 minutes after startup.

              To disable any of the 3 reports, set the corresponding limit  to
              0.   Trailing  zero  arguments  may  be omitted. By default, all
              temperature reports are disabled ('-W 0').

              To track temperature changes of at least 2 degrees, use:
               -W 2
              To log informal messages on temperatures of at least 40 degrees,
              use:
               -W 0,40
              For  warning  messages/mails  on  temperatures  of  at  least 45
              degrees, use:
               -W 0,0,45
              To combine all of the above reports, use:
               -W 2,40,45

              For ATA devices, smartd interprets Attribute 194 as  Temperature
              Celsius by default. This can be changed to Attribute 9 or 220 by
              the drive database or by the '-v' directive, see below.

       -F TYPE
              [ATA only] Modifies the behavior of  smartd  to  compensate  for
              some known and understood device firmware bug.  The arguments to
              this Directive are exclusive, so that only the  final  Directive
              given is used.  The valid values are:

              none   -   Assume   that  the  device  firmware  obeys  the  ATA
              specifications.  This is the  default,  unless  the  device  has
              presets for '-F' in the device database.

              samsung - In some Samsung disks (example: model SV4012H Firmware
              Version: RM100-08) some of the two- and four-byte quantities  in
              the  SMART data structures are byte-swapped (relative to the ATA
              specification).  Enabling this option tells smartd  to  evaluate
              these  quantities  in byte-reversed order.  Some signs that your
              disk needs this option are (1) no self-test  log  printed,  even
              though  you  have  run self-tests; (2) very large numbers of ATA
              errors reported in the ATA error log; (3) strange and impossible
              values for the ATA error log timestamps.

              samsung2  -  In  some  Samsung  disks  the  number of ATA errors
              reported is byte swapped.  Enabling this option tells smartd  to
              evaluate this quantity in byte-reversed order.

              samsung3  -  Some  Samsung disks (at least SP2514N with Firmware
              VF100-37) report a self-test still in progress with 0% remaining
              when  the  test  was  already  completed.  If  this directive is
              specified, smartd will not skip  the  next  scheduled  self-test
              (see Directive '-s' above) in this case.

              Note  that  an explicit '-F' Directive will over-ride any preset
              values for '-F' (see the '-P' option below).

              [Please see the smartctl -F command-line option.]

       -v ID,FORMAT[:BYTEORDER][,NAME]
              [ATA only] Sets a vendor-specific raw  value  print  FORMAT,  an
              optional  BYTEORDER and an optional NAME for Attribute ID.  This
              directive may be used multiple times.  Please  see  smartctl  -v
              command-line option for further details.

              The following arguments affect smartd warning output:

              197,increasing  -  Raw  Attribute  number  197  (Current Pending
              Sector  Count)  is  not  reset  if  uncorrectable  sectors   are
              reallocated.   This sets '-C 197+' if no other '-C' directive is
              specified.

              198,increasing - Raw Attribute number 198 (Offline Uncorrectable
              Sector   Count)   is  not  reset  if  uncorrectable  sector  are
              reallocated.  This sets '-U 198+' if no other '-U' directive  is
              specified.

       -P TYPE
              [ATA  only]  Specifies  whether  smartd  should  use  any preset
              options that are available for this drive.  The valid  arguments
              to this Directive are:

              use  -  use any presets that are available for this drive.  This
              is the default.

              ignore - do not use any presets for this drive.

              show - show the presets listed for this drive in the database.

              showall - show the presets that are available for all drives and
              then exit.

              [Please see the smartctl -P command-line option.]

       -a     Equivalent  to  turning on all of the following Directives: '-H'
              to check the SMART health status, '-f'  to  report  failures  of
              Usage (rather than Prefail) Attributes, '-t' to track changes in
              both Prefailure and Usage Attributes,  '-l selftest'  to  report
              increases  in  the number of Self-Test Log errors, '-l error' to
              report increases in the number of ATA errors, '-C 197' to report
              nonzero values of the current pending sector count, and '-U 198'
              to report nonzero values of the offline pending sector count.

              Note that -a is the default for ATA devices.  If none  of  these
              other Directives is given, then -a is assumed.

       #      Comment: ignore the remainder of the line.

       \      Continuation  character:  if  this is the last non-white or non-
              comment character on a  line,  then  the  following  line  is  a
              continuation of the current one.

       If  you  are  not sure which Directives to use, I suggest experimenting
       for a few minutes with smartctl to see what  SMART  functionality  your
       disk(s)  support(s).   If you do not like voluminous syslog messages, a
       good choice of smartd configuration file Directives might be:
       -H -l selftest -l error -f.
       If you want more frequent information, use: -a.

       If a cciss controller is  used  then  the  corresponding  block  device
       (/dev/cciss/c?d?) must be listed, along with the '-d cciss,N' Directive
       (see below).

       ADDITIONAL DETAILS ABOUT DEVICESCAN
              If a non-comment entry in the configuration  file  is  the  text
              string  DEVICESCAN  in  capital letters, then smartd will ignore
              any remaining lines in the configuration file, and will scan for
              devices.

              [NEW  EXPERIMENTAL  SMARTD  FEATURE]  Configuration  entries for
              devices not found by the platform-specific device  scanning  may
              precede the DEVICESCAN entry.

              If  DEVICESCAN  is  not  followed by any Directives, then smartd
              will scan for both ATA and SCSI devices, and  will  monitor  all
              possible SMART properties of any devices that are found.

              DEVICESCAN  may  optionally be followed by any valid Directives,
              which will be applied to all devices that are found in the scan.
              For example
              DEVICESCAN -m root@example.com
              will  scan for all devices, and then monitor them.  It will send
              one email warning per device for any problems that are found.
              DEVICESCAN -d ata -m root@example.com
              will do the same, but restricts the scan to ATA devices only.
              DEVICESCAN -H -d ata -m root@example.com
              will do the same, but only monitors the SMART health  status  of
              the  devices,  (rather  than  the default -a, which monitors all
              SMART properties).

       EXAMPLES OF SHELL SCRIPTS FOR '-M exec'
              These are two examples of shell scripts that can  be  used  with
              the '-M exec PATH' Directive described previously.  The paths to
              these scripts and similar executables is the  PATH  argument  to
              the '-M exec PATH' Directive.

              Example  1:  This  script  is  for  use with '-m ADDRESS -M exec
              PATH'.  It appends the output of smartctl -a to  the  output  of
              the smartd email warning message and sends it to ADDRESS.

              #! /bin/bash

              # Save the email message (STDIN) to a file:
              cat > /root/msg

              # Append the output of smartctl -a to the message:
              /usr/sbin/smartctl -a -d $SMART_DEVICETYPE $SMARTD_DEVICE >> /root/msg

              # Now email the message to the user at address ADD:
              /bin/mail -s "$SMARTD_SUBJECT" $SMARTD_ADDRESS < /root/msg

              Example  2:  This  script is for use with '-m <nomailer> -M exec
              PATH'. It warns  all  users  about  a  disk  problem,  waits  30
              seconds, and then powers down the machine.

              #! /bin/bash

              # Warn all users of a problem
              wall 'Problem detected with disk: ' "$SMARTD_DEVICESTRING"
              wall 'Warning message from smartd is: ' "$SMARTD_MESSAGE"
              wall 'Shutting down machine in 30 seconds... '

              # Wait half a minute
              sleep 30

              # Power down the machine
              /sbin/shutdown -hf now

              Some  example  scripts  are  distributed  with the smartmontools
              package, in /usr/share/doc/smartmontools/examples/.

              Please note that these scripts typically run  as  root,  so  any
              files  that  they  read/write should not be writable by ordinary
              users or reside in directories like /tmp that  are  writable  by
              ordinary users and may expose your system to symlink attacks.

              As  previously  described,  if  the  scripts  write to STDOUT or
              STDERR, this is interpreted as  indicating  that  there  was  an
              internal error within the script, and a snippet of STDOUT/STDERR
              is logged to SYSLOG.  The remainder is flushed.
