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.

USAGE

       lvm lvpoll --polloperation pvmove|convert|merge|merge_thin LV ...
           [ -A|--autobackup y|n ]
           [ -i|--interval Number ]
           [    --abort ]
           [    --handlemissingpvs ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config String ]
           [    --driverloaded y|n ]
           [    --longhelp ]
           [    --profile String ]
           [    --version ]

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 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.

       --longhelp
              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'.

       -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:
              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

       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
