extnending a logical volume
based on the following information does my lvextend command look ok:
lvdisplay /dev/VolGroup02/u03 shows this
- lv name = /dev/VolGroup02/u03
- vg name = VolGroup02
df /u03
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup02-u03
103212320 77407636 20561804 80% /u03
pv shows
/dev/sdc VolGroup02 2.27T (size) 2.17T (free)
i want to extend the logical volume /dev/VolGroup02/u03 by 100gb
lvextend -r -L +100G /dev/VolGroup02/u03 dev/sdc
and is it necessary to unmount it first ?
