SYNOPSIS

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

DESCRIPTION

17       lvpoll  is  an internal command used by lvmpolld(8) to monitor and com‐
18       plete lvconvert(8) and pvmove(8) operations.  lvpoll  itself  does  not
19       initiate  these operations and you should never normally need to invoke
20       it directly.
21
22       LogicalVolume The Logical Volume undergoing conversion or, in the  case
23       of  pvmove,  the  name of the internal pvmove Logical Volume (see EXAM‐
24       PLES).

OPTIONS

27       See lvm(8) for common options.
28
29       --polloperation {convert|merge|merge_thin|pvmove}
30              Mandatory option.  pvmove refers to a pvmove operation  that  is
31              moving  data.  convert refers to an operation that is increasing
32              the number of redundant copies of data maintained by  a  mirror.
33              merge indicates a merge operation that doesn't involve thin vol‐
34              umes.  merge_thin indicates a  merge  operation  involving  thin
35              snapshots.   pvmove(8) and lvconvert(8) describe how to initiate
36              these operations.
37
38       --abort
39              Abort pvmove in progress.  See pvmove(8).
40
41       --handlemissingpvs
42              Used when the polling operation needs to handle missing  PVs  to
43              be  able  to  continue.  This  can  happen  when lvconvert(8) is
44              repairing a mirror with one or more faulty devices.
45
46       -i, --interval Seconds
47              Report progress at regular intervals

EXAMPLES

51       Resume polling of a pvmove operation identified by the  Logical  Volume
52       vg00/pvmove0:
53
54       lvm lvpoll --polloperation pvmove vg00/pvmove0
55
56       Abort the same pvmove operation:
57
58       lvm lvpoll --polloperation pvmove --abort vg00/pvmove0
59
60       To  find  out  the  name of the pvmove Logical Volume resulting from an
61       original pvmove /dev/sda1 command you may use the  following  lvs  com‐
62       mand.  (Remove the parentheses from the LV name.)
63
64       lvs -a -S move_pv=/dev/sda1
65
66       Resume polling of mirror conversion vg00/lvmirror:
67
68       lvm lvpoll --polloperation convert vg00/lvmirror
69
70       Complete mirror repair:
71
72       lvm lvpoll --polloperation convert vg/damaged_mirror --handlemissingpvs
73
74       Process snapshot merge:
75
76       lvm lvpoll --polloperation merge vg/snapshot_old
77
78       Finish thin snapshot merge:
79
80       lvm lvpoll --polloperation merge_thin vg/thin_snapshot
