.SH DESCRIPTION
|
||
|
|
.B pvmove
|
||
|
|
allows you to move the allocated physical extents (PEs) on
|
||
|
|
.I SourcePhysicalVolume
|
||
|
|
to one or more other physical volumes (PVs).
|
||
|
|
You can optionally specify a source
|
||
|
|
.I LogicalVolume
|
||
|
|
in which case only extents used by that LV will be moved to
|
||
|
|
free (or specified) extents on
|
||
|
|
.IR DestinationPhysicalVolume (s).
|
||
|
|
If no
|
||
|
|
.I DestinationPhysicalVolume
|
||
|
|
is specifed, the normal allocation rules for the volume group are used.
|
||
|
|
|
||
|
|
If \fBpvmove\fP gets interrupted for any reason, it will probably be
|
||
|
|
necessary to run \fBvgcfgrestore\fP to restore the volume group's metadata to
|
||
|
|
the state it was before the \fBpvmove\fP began.
|
||
|
|
|
||
|
|
\fBpvmove\fP locks the volume group and other LVM2 commands can't access
|
||
|
|
the volume group metadata until \fBpvmove\fP has completed.

.I \-n, \-\-name " \fILogicalVolume\fR"
|
||
|
|
Move only the extents belonging to
|
||
|
|
.I LogicalVolume
|
||
|
|
from
|
||
|
|
.I SourcePhysicalVolume
|
||
|
|
instead of all allocated extents to the destination physical volume(s).

|
||
|
|
.SH EXAMPLES
|
||
|
|
To move all logical extents of any logical volumes on
|
||
|
|
.B /dev/hda4
|
||
|
|
to free physical extents elsewhere in the volume group, giving verbose
|
||
|
|
runtime information, use:
|
||
|
|
.sp
|

|
|
\ pvmove -v /dev/hda4
