.SH DESCRIPTION
|
||
|
|
\fBlvpoll\fP is an internal command used by \fBlvmpolld\fP(8) to monitor and
|
||
|
|
complete \fBlvconvert\fP(8) and \fBpvmove\fP(8) operations.
|
||
|
|
\fBlvpoll\fP itself does not initiate these operations and
|
||
|
|
you should never normally need to invoke it directly.
|
||
|
|
|
||
|
|
.I LogicalVolume
|
||
|
|
The Logical Volume undergoing conversion or, in the case of pvmove, the name of
|
||
|
|
the internal pvmove Logical Volume (see \fBEXAMPLES\fP).
|
||
|
|
.SH OPTIONS
|
||
|
|
See \fBlvm\fP(8) for common options.
|
||
|
|
.TP
|
||
|
|
.BR \-\-polloperation " {" \fIconvert | \fImerge | \fImerge_thin | \fIpvmove }
|
||
|
|
Mandatory option.
|
||
|
|
\fIpvmove\fP refers to a pvmove operation that is moving data.
|
||
|
|
\fIconvert\fP refers to an operation that is increasing the number of redundant copies of data maintained by a mirror.
|
||
|
|
\fImerge\fP indicates a merge operation that doesn't involve thin volumes.
|
||
|
|
\fImerge_thin\fP indicates a merge operation involving thin snapshots.
|
||
|
|
\fBpvmove\fP(8) and \fBlvconvert\fP(8) describe how to initiate these operations.
|
||
|
|
.TP
|
||
|
|
.B \-\-abort
|
||
|
|
Abort pvmove in progress. See \fBpvmove\fP(8).
|
||
|
|
.TP
|
||
|
|
.B \-\-handlemissingpvs
|
||
|
|
Used when the polling operation needs to handle missing PVs to be able to
|
||
|
|
continue. This can happen when \fBlvconvert\fP(8) is repairing a mirror
|
||
|
|
with one or more faulty devices.
|
||
|

.SH EXAMPLES
|
||
|
|
Resume polling of a pvmove operation identified by the Logical Volume vg00/pvmove0:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation pvmove vg00/pvmove0
|
||
|
|
.P
|
||
|
|
Abort the same pvmove operation:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation pvmove --abort vg00/pvmove0
|
||
|
|
.P
|
||
|
|
To find out the name of the pvmove Logical Volume resulting from an original
|
||
|
|
\fBpvmove /dev/sda1\fP command you may use the following \fBlvs\fP command.
|
||
|
|
(Remove the parentheses from the LV name.)
|
||
|
|
.sp
|
||
|
|
.B lvs -a -S move_pv=/dev/sda1
|
||
|
|
.P
|
||
|
|
Resume polling of mirror conversion vg00/lvmirror:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation convert vg00/lvmirror
|
||
|
|
.P
|
||
|
|
Complete mirror repair:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation convert vg/damaged_mirror --handlemissingpvs
|
||
|
|
.P
|
||
|
|
Process snapshot merge:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation merge vg/snapshot_old
|
||
|
|
.P
|
||
|
|
Finish thin snapshot merge:
|
||
|
|
.sp
|
||
|
|
.B lvm lvpoll --polloperation merge_thin vg/thin_snapshot
