.SH EXAMPLES
|
||
|
|
|
||
|
|
Move all physical extents that are used by simple LVs on the specified PV to
|
||
|
|
free physical extents elsewhere in the VG.
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1
|
||
|
|
|
||
|
|
Use a specific destination PV when moving physical extents.
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1 /dev/sdc1
|
||
|
|
|
||
|
|
Move extents belonging to a single LV.
|
||
|
|
.br
|
||
|
|
.B pvmove \-n lvol1 /dev/sdb1 /dev/sdc1
|
||
|
|
|
||
|
|
Rather than moving the contents of an entire device, it is possible to
|
||
|
|
move a range of physical extents, for example numbers 1000 to 1999
|
||
|
|
inclusive on the specified PV.
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1:1000\-1999
|
||
|
|
|
||
|
|
A range of physical extents to move can be specified as start+length. For
|
||
|
|
example, starting from PE 1000. (Counting starts from 0, so this refers to the
|
||
|
|
1001st to the 2000th PE inclusive.)
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1:1000+1000
|
||
|
|
|
||
|
|
Move a range of physical extents to a specific PV (which must have
|
||
|
|
sufficient free extents).
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1:1000\-1999 /dev/sdc1
|
||
|
|
|
||
|
|
Move a range of physical extents to specific new extents on a new PV.
|
||
|
|
.br
|
||
|
|
.B pvmove /dev/sdb1:1000\-1999 /dev/sdc1:0\-999
|
||
|
|
|
||
|
|
If the source and destination are on the same disk, the
|
||
|
|
\fBanywhere\fP allocation policy is needed.
|
||
|
|
.br
|
||
|
|
.B pvmove \-\-alloc anywhere /dev/sdb1:1000\-1999 /dev/sdb1:0\-999
|
||
|
|
|
||
|
|
The part of a specific LV present within in a range of physical
|
||
|
|
extents can also be picked out and moved.
|
||
|
