NAME
smartd.conf - SMART Disk Monitoring Daemon Configuration File
FULL PATH
/etc/smartd.conf
PACKAGE VERSION
smartmontools-6.2 2013-07-26 r3841
DESCRIPTION
[This man page is generated for the Linux version of smartmontools. It does not contain
info specific to other platforms.]
/etc/smartd.conf is the configuration file for the smartd daemon.
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.
In the absence of a configuration file smartd will try to open all available devices (see
smartd(8) man page). A configuration file with a single line ´DEVICESCAN -a' would have
the same effect.
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 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:
• There should be one device listed per line, although you may have lines that are
entirely comments or white space.
• Any text following a hash sign ´#´ and up to the end of the line is taken to be a
comment, and ignored.
• Lines may be continued by using a backslash ´\´ as the last non-whitespace or non-
comment item on a line.
• 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.
[NEW EXPERIMENTAL SMARTD FEATURE] If an entry in the configuration file starts with
DEFAULT instead of a device name, then all directives in this entry are set as defaults
for the next device entries.
This configuration:
DEFAULT -a -R5! -W 2,40,45 -I 194 -s L/../../7/00 -m admin@example.com
/dev/sda
/dev/sdb
/dev/sdc
DEFAULT -H -m admin@example.com
/dev/sdd
/dev/sde -d removable
has the same effect as:
/dev/sda -a -R5! -W 2,40,45 -I 194 -s L/../../7/00 -m admin@example.com
/dev/sdb -a -R5! -W 2,40,45 -I 194 -s L/../../7/00 -m admin@example.com
/dev/sdc -a -R5! -W 2,40,45 -I 194 -s L/../../7/00 -m admin@example.com
/dev/sdd -H -m admin@example.com
/dev/sde -d removable -H -m admin@example.com
The following are the Directives that may appear following the device name or DEVICESCAN
or DEFAULT 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?, /dev/twl? or /dev/tws?) 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 device (SCSI /dev/sg? on Linux or
/dev/arcmsr0 on FreeBSD) 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[,auto][,N] - 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´.
If ´-d sat,auto´ is specified, device type SAT (for ATA/SATA disks) is only used if
the SCSI INQUIRY data reports a SATL (VENDOR: "ATA "). Otherwise device type
SCSI (for SCSI/SAS disks) is used.
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[,p][,x][,PORT] - 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.
[NEW EXPERIMENTAL SMARTD FEATURE] The Prolific PL2507/3507 USB bridges with older
firmware support a pass-through command similar to JMicron and work with ´-d
usbjmicron,0´. Newer Prolific firmware requires a modified command which can be
selected by ´-d usbjmicron,p´. Note that this does not yet support the SMART
status command.
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. It is possible to set RAID device name as /dev/bus/N,
where N is a SCSI bus number. 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 - [FreeBSD, Linux, Windows and Cygwin 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.
areca,N/E - [FreeBSD, Linux, Windows and Cygwin only] [NEW EXPERIMENTAL SMARTD
FEATURE] the device consists of one or more SATA or SAS disks connected to an Areca
SAS RAID controller. The integer N (range 1 to 128) denotes the channel (slot) and
E (range 1 to 8) denotes the enclosure. Important: This requires Areca SAS
controller firmware version 1.51 or later.
cciss,N - [FreeBSD and Linux only] the device consists of one or more SCSI/SAS or
SATA 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 128 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.
ignore - [NEW EXPERIMENTAL SMARTD FEATURE] the device specified by this
configuration entry should be ignored. This allows to ignore specific devices
which are detected by a following DEVICESCAN configuration line. It may also be
used to temporary disable longer multi-line configuration entries. This Directive
may be used in conjunction with the other ´-d´ Directives.
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. [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] 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. The warning email counter is reset if the number of failed self tests
dropped to 0. This typically happens when an extended self-test is run after all
bad sectors have been reallocated.
offlinests[,ns] - [ATA only] report if the Offline Data Collection status has
changed since the last check. The report will be logged as LOG_CRIT if the new
status indicates an error. With some drives the status often changes, therefore
´-l offlinests´ is not enabled by '-a´ Directive. Appending ´,ns´ (no standby) to
this directive is not implemented on Linux.
selfteststs[,ns] - [ATA only] report if the Self-Test execution status has changed
since the last check. The report will be logged as LOG_CRIT if the new status
indicates an error. Appending ´,ns´ (no standby) to this directive is not
implemented on Linux.
scterc,READTIME,WRITETIME - [ATA only] 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.]
-e NAME[,VALUE]
Sets non-SMART device settings when smartd starts up and has no further effect.
[Please see the smartctl --set command-line option.] Valid arguments are:
aam,[N|off] - [ATA only] Sets the Automatic Acoustic Management (AAM) feature.
apm,[N|off] - [ATA only] Sets the Advanced Power Management (APM) feature.
lookahead,[on|off] - [ATA only] Sets the read look-ahead feature.
security-freeze - [ATA only] Sets ATA Security feature to frozen mode.
standby,[N|off] - [ATA only] Sets the standby (spindown) timer and places the drive
in the IDLE mode.
wcache,[on|off] - [ATA only] Sets the volatile write cache feature.
-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.
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 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.
[NEW EXPERIMENTAL SMARTD FEATURE] If a word of the comma separated list has the
form ´@plugin´, a custom script /etc/smartd_warning.d/plugin is run and the word is
removed from the list before sending mail. The string ´plugin´ may be any valid
name except ´ALL´. If ´@ALL´ is specified, all scripts in /etc/smartd_warning.d/*
are run instead. This is handled by the script /etc/smartd_warning.sh (see also
´-M exec´ below).
-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.
If a disk problem is no longer detected, the internal email counter is reset. If
the problem reappears a new warning email is sent immediately.
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]´ on Linux or
´/dev/arcmsr0 [areca_disk_09]´ on FreeBSD. 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_DEVICEINFO
is set to device identify information. It includes most of the info printed by
smartctl -i but uses a brief single line format. This device info is also
logged when smartd starts up. The string contains space characters and is NOT
quoted.
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 $SMARTD_FULLMESSAGE in a bash script you should probably enclose it in
double quotes.
SMARTD_TFIRST
is a text string giving the time and date at which the first problem of this
type was reported. This text string contains space characters and no newlines,
and is NOT quoted. For example:
Sun Feb 9 14:58:19 2003 CST
SMARTD_TFIRSTEPOCH
is an integer, which is the unix epoch (number of seconds since Jan 1, 1970)
for SMARTD_TFIRST.
SMARTD_PREVCNT
is an integer specifying the number of previous messages sent. It is set to
´0´ for the first message.
SMARTD_NEXTDAYS
is an integer specifying the number of days until the next message will be
sent. It it set to empty on ´-M once´ and set to ´1´ on ´-M daily´.
The shell which is used to run PATH is system-dependent. For vanilla Linux/glibc
it´s bash. For other systems, the man page for popen(3) should say what shell is
used.
If the ´-m ADD´ Directive is given with a normal address argument, then the
executable pointed to by PATH will be run in a shell with STDIN receiving the body
of the email message, and with the same command-line arguments:
-s "$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
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//.
[NEW EXPERIMENTAL SMARTD FEATURE] The executable is run by the script
/etc/smartd_warning.sh. This script formats subject and full message based on
SMARTD_MESSAGE and other environment variables set by smartd. The environment
variables SMARTD_SUBJECT and SMARTD_FULLMESSAGE are set by the script before
running the executable.
-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. [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. [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.
The warning email counter is reset if the number of pending sectors dropped to 0.
This typically happens when all pending sectors have been reallocated or could be
read again.
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.
The warning email counter is reset if the number of offline uncorrectable sectors
dropped to 0. This typically happens when all offline uncorrectable sectors have
been reallocated or could be read again.
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.
The warning email counter is reset if the temperature dropped below INFO or CRIT-5
if INFO is not specified.
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 or 190 as Temperature Celsius by
default. This can be changed to Attribute 9 or 220 by the drive database or by the
´-v 9,temp´ or ´-v 220,temp´ directive.
-F TYPE
[ATA only] Modifies the behavior of smartd to compensate for some known and
understood device firmware bug. This directive may be used multiple times. The
valid arguments are:
none - Assume that the device firmware obeys the ATA specifications. This is the
default, unless the device has presets for ´-F´ in the drive database. Using this
directive will over-ride any preset values.
nologdir - Suppresses read attempts of SMART or GP Log Directory. Support for all
standard logs is assumed without an actual check. Some Intel SSDs may freeze if
log address 0 is read.
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.
xerrorlba - This only affects smartctl.
[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 error´ to report
increases in the number of ATA errors, ´-l selftest´ to report increases in the
number of Self-Test Log errors, ´-l selfteststs´ to report changes of Self-Test
execution status, ´-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 (see also smartd(8) man page).
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).
[NEW EXPERIMENTAL SMARTD FEATURE] Configuration entries for specific devices may
precede the DEVICESCAN entry. For example
DEFAULT -m root@example.com
/dev/sda -s S/../.././02
/dev/sdc -d ignore
DEVICESCAN -s L/../.././02
will scan for all devices except /dev/sda and /dev/sdc, monitor them, and run a
long test between 2-3am every morning. Device /dev/sda will also be monitored, but
only a short test will be run. Device /dev/sdc will be ignored. Warning emails
will be sent for all monitored devices.
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.
