Hi,

I am having following problem with ext2online utility under Suse

I have volume group (vg0) of size 80 GB
I have partition /dev/vg0/lvopt of size 6GB
I extended this partition to 30 GB via lvextend.
I cannot somehow extend lvopt beyond 16 GB using ext2online utility.

This is what Suse is telling me to do
a) goto single user mode
b) umount /opt
c) lvexend -L 30 GB /dev/vg0/lvopt
d)e2fsck -f /dev/vg0/lvopt
e) resize2fs /dev/vg0/lvopt
f)mount /opt (make sure its 16 GB)
g) reboot to multiuser mode.

I did steps told by suse and they work. However the problem is I
cannot bring all servers to single user mode just to do it. There must
be easier way while the filesystem is mounted.

I don't think so. Ext2/3 resizing is not very good. It's dependence
upon being fsck'd being one of the biggest problems with it. Even then,
a resize of the size you mention could take many, many, many minutes.

Ext2/3 is not easily resized.... and it really doesn't like to be
resized online. If resizing on the fly is important, use reiserfs.

If somebody knows some kind of magic to make ext2/3 resizing work
reasonably well.... please post. But AFAIK, the operation is really
just beyond the architecture of the filesystem.- Hide quoted text -

Suse is moving off od reiserfs in 10.1 (next month)
