NAME

       lvm lvpoll — Continue already initiated poll operation on a logical volume

SYNOPSIS

       lvm lvpoll option_args position_args
           [ option_args ]

DESCRIPTION

       lvm  lvpoll is an internal command used by lvmpolld(8) to monitor and complete lvconvert(8) and pvmove(8)
       operations. lvpoll itself does not initiate these operations and should  not  normally  need  to  be  run
       directly.

       lvm lvpoll --polloperation pvmove|convert|merge|merge_thin LV ...

OPTIONS

       --abort
              Stop processing a poll operation in lvmpolld.

       -A|--autobackup y|n
              Specifies if metadata should be backed up automatically after a change.  Enabling this is strongly
              advised! See vgcfgbackup(8) for more information.

       --commandprofile String
              The command profile to use for command configuration.  See lvm.conf(5) for more information  about
              profiles.

       --config String
              Config  settings  for  the  command. These override lvm.conf(5) settings.  The String arg uses the
              same format as lvm.conf(5), or may use section/field syntax.  See lvm.conf(5) for more information
              about config.

       -d|--debug ...
              Set  debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file
              and/or syslog (if configured).

       --devices PV
              Restricts the devices that are visible and accessible to the command.   Devices  not  listed  will
              appear  to  be missing. This option can be repeated, or accepts a comma separated list of devices.
              This overrides the devices file.

       --devicesfile String
              A file listing devices that LVM should use.  The file  must  exist  in  /etc/lvm/devices/  and  is
              managed  with  the  lvmdevices(8) command.  This overrides the lvm.conf(5) devices/devicesfile and
              devices/use_devicesfile settings.

       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.  For testing and debugging.

       --handlemissingpvs
              Allows a polling operation to continue when PVs are  missing,  e.g.  for  repairs  due  to  faulty
              devices.

       -h|--help
              Display help text.

       -i|--interval Number
              Report progress at regular intervals.

       --journal String
              Record information in the systemd journal.  This information is in addition to information enabled
              by the lvm.conf log/journal setting.  command: record  information  about  the  command.   output:
              record the default command output.  debug: record full command debugging.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       --nohints
              Do  not  use the hints file to locate devices for PVs. A command may read more devices to find PVs
              when hints are not used. The command will still perform  standard  hint  file  invalidation  where
              appropriate.

       --nolocking
              Disable locking. Use with caution, concurrent commands may produce incorrect results.

       --polloperation pvmove|convert|merge|merge_thin
              The command to perform from lvmpolld.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on the command.

       -q|--quiet ...
              Suppress  output  and log messages. Overrides --debug and --verbose.  Repeat once to also suppress
              any prompts with answer 'no'.

       -t|--test
              Run in test mode. Commands will not  update  metadata.   This  is  implemented  by  disabling  all
              metadata  writing  but  nevertheless  returning  success to the calling function. This may lead to
              unusual error messages in multi-stage operations if a tool relies  on  reading  back  metadata  it
              believes has changed but hasn't.

       -v|--verbose ...
              Set  verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and
              stderr.

       --version
              Display version information.

       -y|--yes
              Do not prompt for confirmation interactively but always assume the answer yes.  Use  with  extreme
              caution.  (For automatic no, see -qq.)

VARIABLES

       LV     Logical  Volume name.  See lvm(8) for valid names.  An LV positional arg generally includes the VG
              name and LV name, e.g. VG/LV.

       String See the option description for information about the string content.

       Size[UNIT]
              Size is an input number that accepts an optional unit.  Input units are always treated as base two
              values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.  The default input unit
              is specified by letter, followed by |UNIT.  UNIT represents other possible  input  units:  b|B  is
              bytes,  s|S  is  sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB,
              e|E is EiB.  (This should not be confused with the output control --units, where  capital  letters
              mean multiple of 1000.)

ENVIRONMENT VARIABLES

       See  lvm(8)  for  information  about  environment  variables  used  by lvm.  For example, LVM_VG_NAME can
       generally be substituted for a required VG parameter.

NOTES

       To find the name of the pvmove LV that was created by an  original  pvmove  /dev/name  command,  use  the
       command:
       lvs -a -S move_pv=/dev/name.

EXAMPLES

       Continue polling a pvmove operation.
       lvm lvpoll --polloperation pvmove vg00/pvmove0

       Abort a pvmove operation.
       lvm lvpoll --polloperation pvmove --abort vg00/pvmove0

       Continue polling a mirror conversion.
       lvm lvpoll --polloperation convert vg00/lvmirror

       Continue mirror repair.
       lvm lvpoll --polloperation convert vg/damaged_mirror --handlemissingpvs

       Continue snapshot merge.
       lvm lvpoll --polloperation merge vg/snapshot_old

       Continue thin snapshot merge.
       lvm lvpoll --polloperation merge_thin vg/thin_snapshot
