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

NAME         top

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

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 directly.

OPTIONS         top

       --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
              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
              configured).

       --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.

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

       --longhelp
              Display long help text.

       --nolocking
              Disable locking.

       --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         top

       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: 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.)

ENVIRONMENT VARIABLES         top

       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.

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