NAME         top

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

SYNOPSIS         top

       lvm lvpoll --polloperation {pvmove|convert|merge|merge_thin}

DESCRIPTION         top

       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

OPTIONS         top

       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 pvmove in progress.  See pvmove(8).

              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         top

       Resume polling of a pvmove operation identified by the Logical Volume

       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

       Process snapshot merge:

       lvm lvpoll --polloperation merge vg/snapshot_old

       Finish thin snapshot merge:

       lvm lvpoll --polloperation merge_thin vg/thin_snapshot
