NAME

       lvpoll — Internal command used by lvmpolld to complete some Logical Volume operations.

SYNOPSIS

       lvm   lvpoll   --polloperation   {pvmove|convert|merge|merge_thin}   [--abort]   [-A|--autobackup  {y|n}]
       [--commandprofile ProfileName] [-d|--debug] [-h|-?|--help] [--handlemissingpvs]  [-i|--interval  Seconds]
       [-t|--test] [-v|--verbose] [--version] LogicalVolume[Path]

DESCRIPTION

       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  you  should  never  normally  need  to
       invoke it directly.

       LogicalVolume  The  Logical  Volume  undergoing  conversion  or,  in  the case of pvmove, the name of the
       internal pvmove Logical Volume (see EXAMPLES).

OPTIONS

       See lvm(8) for common options.

       --polloperation {convert|merge|merge_thin|pvmove}
              Mandatory option.  pvmove refers to a pvmove operation that is moving data.  convert refers to  an
              operation that is increasing the number of redundant copies of data maintained by a mirror.  merge
              indicates  a  merge  operation  that  doesn't  involve thin volumes.  merge_thin indicates a merge
              operation involving thin snapshots.  pvmove(8) and lvconvert(8) describe  how  to  initiate  these
              operations.

       --abort
              Abort pvmove in progress.  See pvmove(8).

       --handlemissingpvs
              Used  when  the  polling  operation  needs  to handle missing PVs to be able to continue. This can
              happen when lvconvert(8) is repairing a mirror with one or more faulty devices.

       -i, --interval Seconds
              Report progress at regular intervals

EXAMPLES

       Resume polling of a pvmove operation identified by the Logical Volume vg00/pvmove0:

       lvm lvpoll --polloperation pvmove vg00/pvmove0

       Abort the same pvmove operation:

       lvm lvpoll --polloperation pvmove --abort vg00/pvmove0

       To find out the name of the pvmove Logical Volume resulting from an original pvmove /dev/sda1 command you
       may use the following lvs command.  (Remove the parentheses from the LV name.)

       lvs -a -S move_pv=/dev/sda1

       Resume polling of mirror conversion vg00/lvmirror:

       lvm lvpoll --polloperation convert vg00/lvmirror

       Complete mirror repair:

       lvm lvpoll --polloperation convert vg/damaged_mirror --handlemissingpvs

       Process snapshot merge:

       lvm lvpoll --polloperation merge vg/snapshot_old

       Finish thin snapshot merge:

       lvm lvpoll --polloperation merge_thin vg/thin_snapshot
