Please Ignore my last post.<br>
<br>
I recreated my vg with the --clustered option, now I get:<br>
<br>
Clustered snapshots are not yet supported.<br>
<br>
I read some things like that, but was under the impression that this
was added in a more recent release.<br>
<br>
I think I'll have to change my setup to:<br>
<br>
Disk -> LVM -> DRBD -> OCFS2 (As in Kaloyan's post: DRBD on
top op LVM, not the other way around... :-))<br>
<br>
Cheers,<br>

Hi,<br>
<br>
I've changed my setup, I know have:<br>
<br>
Disk -> DRBD -> LVM -> OCFS2<br>
<br>
I have clvm and lvm2 running (both clones) and things seem to work
fine. (After some fiddeling, I'm new to LVM. I needed cLVM to get
things working smooth).<br>
<br>
I can create a snapshot volume, but I fail to succesfully change
the UUID / volume label:<br>
<br>
root@scan1:~# lvcreate -s -L 50G -n SS /dev/r0/scans<br>
Logical volume "SS" created<br>
root@scan1:~# tunefs.ocfs2 --cloned-volume -L SS /dev/r0/SS<br>
Updating the UUID and label on cloned volume "/dev/r0/SS".<br>
DANGER: THIS WILL MODIFY THE UUID WITHOUT ACCESSING THE CLUSTER
SOFTWARE. YOU MUST BE ABSOLUTELY SURE THAT NO OTHER NODE IS USING
THIS FILESYSTEM BEFORE MODIFYING ITS UUID.<br>
Update the UUID and label? y<br>
tunefs.ocfs2: OCFS2 inode is not a directory while opening device
"/dev/r0/SS"<br>
<br>
Anyone familiar with this setup / error message?<br>
<br>
Thank you in advance,<br>
<br>
Dirk<br>

<pre wrap="">If you are using DRBD on top of LVM you can make use of snapshots and
mount the snapshot with local locking. Here is an example from my backup
script:
lvcreate -s -L 100G -n LVMsnapshot /dev/vg0/lv0
tunefs.ocfs2 -y -L LVMsnapshot --cloned-volume /dev/vg0/LVMsnapshot
mount -o ro,localflocks /dev/vg0/LVMsnapshot /mnt/LVMsnapshot/
rsync -a --delete /mnt/LVMsnapshot/ ${BACKUP_LOCATION}
umount /mnt/LVMsnapshot
lvremove -f /dev/vg0/LVMsnapshot
