Online resize of mounted ext3 logical volume

Question

I am on SLES10 and am trying to extend the size of /usr I did:

lvextend -L +5G /dev/vg00/vol03

which seemed to work. Now when I try to do:

resize2fs /dev/vg00/vol03 11G

I get:

an ... is mounted; can't resize a mounted filesystem

I also tried:

ext2online /dev/vg00/vol03 11G

which results in:

warning - device size 157...., specified 288.... error invalid argument: seeking to 11811155968

The host is an VMWARE SLES9 so I can't boot from CD and therefore can not unmount /usr

Please Help.

Solution 1

Don't specify the size of the new partition when you run ext2online, just let it run and auto-detect.

You've probably specified a size that's slightly larger than the actual LV.

Solution 2

Grab a linux boot CD like the Gparted live CD iso or the ubuntu desktop distro iso and resize your volume from there. You can mount the iso in the virtual cd-rom drive for your virtual machine.

I am such a noob - I followed this thread forums.debian.net/viewtopic.php?t=29143 last post - and now I got lost 5 GB somewhere. I Resized /home from 10GB to 5GB and now I can not increase my /usr where could the 5 GB be???
