LVM(LVPOLL)                    (8)                    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.

     USAGE
          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 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
          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 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
