NAME         top

       lvm  lvpoll  - Continue already initiated poll operation on a logical

SYNOPSIS         top

       lvm lvpoll option_args position_args
           [ option_args ]

DESCRIPTION         top

       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

OPTIONS         top

              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
              settings.  The String arg uses the same format as lvm.conf, 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

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

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

              Display help text.

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

              Display long help text.

       --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'.

              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

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

              Display version information.

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

VARIABLES         top

              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.

              See the option description for information about the string

              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: bBsSkKmMgGtTpPeE.
              b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes,
              m|M is megabytes, g|G is gigabytes, t|T is terabytes, p|P is
              petabytes, e|E is exabytes.  (This should not be confused with
              the output control --units, where capital letters mean
              multiple of 1000.)


       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         top

       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         top

       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

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

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