LVM(LVPOLL)                                 Red Hat, Inc.                                LVM(LVPOLL)

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.

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 infor‐
              mation 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 sep‐
              arated 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) de‐
              vices/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  de‐
              bugging.

       --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  infor‐
              mation 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 informa‐
              tion.

       --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 read‐
              ing 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 in‐
              cludes 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
