EXAMPLES
Split the mirrored logical volume
/dev/vg00/lvol1
into two copies. Call the new logical volume
/dev/vg00/lvol1backup
:
lvsplit -s backup /dev/vg00/lvol1
Split the mirrored logical volume /dev/vg00/lvol1
into two copies. The offline logical volume will be
created using the mirror copy on the physical volumes contained in the physical volume group
pvg1
.
lvsplit -g pvg1 /dev/vg00/lvol1
Split an online logical volume which is currently mounted on /usr so that a backup can take place:
lvsplit /dev/vg00/lvol1
fsck /dev/vg00/lvol1b
mount /dev/vg00/lvol1b /usr.backup
Perform a backup operation, then:
umount /usr.backup
lvmerge /dev/vg00/lvol1b /dev/vg00/lvol1
Split two logical volumes at the same time:
lvsplit /dev/vg01/database1 /dev/vg01/database2
Perform a backup operation on the split logical volumes, then rejoin them:
lvmerge /dev/vg01/database1b /dev/vg01/database1
lvmerge /dev/vg01/database2b /dev/vg01/database2
