do you use resize2fs to do this. If so can you give an example so I make sure I do the syntax properly (man page doesn't show)
thanks,

hello all,
I am trying to expand my /var file system which resides on a logical volume. I successfully issued the lvextend command. However when I try to issue the ext2online command I receive a return code of 3 which the man pages indicates:
ext2online /var ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: group 0, block 7 not reserved
ext2online: unable to resize /dev/mapper/root_vg-lv_var
echo $? 3
3 Error in pre-resizing (user space) operation
Can someone tell me what I'm doing wrong. I would prefer doing this online...
thanks,
James
I think it would be much safer to do it offline. Online resizing only came to be in kernel 2.6.7 somewhere, and I haven't seen anything saying it was real safe yet.
resize2fs /dev/volgroup/volname should resize the filesystem to fill the extended space. You could try it with the trial run parameter to check. But this is offline... Next time look at e2fsadm. It can resize the logical volume and the ext2/3 filesystem in one command. Look at http://www.tldp.org/HOWTO/LVM-HOWTO/extendlv.html
