Re: [linux-lvm] lv extend

[Tom Dawes-Gamble <tmdg@uksr.hp.com>]

Hi,

	This seems a Frequent problem we get it on HP-UX LVM too.
People do an lvextend and then wonder why the filesystem has not grown
to fill the lvol.

	Perhaps a message like.

[root@ocalhost /root]# lvextend -l 256 /dev/vg01/lvol2
lvextend -- extending logical volume "/dev/vg01/lvol2" to 1 GB
lvextend -- doing automatic backup of volume group "vg01"
lvextend -- logical volume "/dev/vg01/lvol2" successfully extended

Note:  You need to run a resize utility such as ext2resize before
	the space is available in the file system.

[root@localhost /root]#

Or lvextend could check the mount table and offer to run ext2resize
for you.  If that seems like a neat idea I would be willing to write
the code.

Regards,
Tom.
