 |
|
Need to extend an LVM partition (ext3) to save data from a failing drive. Is the below commands the proper way to extend the partition? When I do this does the partition need to be unmounted for both commands?
# lvextend -L+50G /dev/vg/home
# resize2fs /dev/vg/home
must be unmounted to resize the partition

You can resize the volume under the filesystem live -- it has no affect on the filesystem.
ext2 filesystems usually need to be dismounted to reduce, but can (depending on version) be extended on the fly *if* there is sufficient free filesystem space to start.
reiserfs filesystems can be extended on the fly, reduced on the fly, depending on free space.

try | Code: | | lvextend -L +5oG -r /dev/vg/home |
which might well manage to resize the fs at the same time.
if you are unsure - add a -t to the lvextend command and it will TEST the command without doing anything.
