Hello again, after a while the setup stopped working completely. Even though the status (cat /proc/drbd) showed that everything was ok on both nodes the following message was issued when trying to mount the device on the first node
root@node1:[/tmp] # mount -t ocfs2 /dev/drbd2 /var/www/ mount.ocfs2: Unable to access cluster service while trying to join the group After rebooting both nodes things still did not work out. The attempt to mount the device manually ended up with the message root@node1:[~] # mount -t ocfs2 /dev/drbd2 /var/www/ mount.ocfs2: Device or resource busy while mounting /dev/drbd2 on /var/www/. Check 'dmesg' for more information on this error. I was not able to see anything related in dmesg. I suspect that the problems might have to do with the fact that I used the device in a master/ slave setup before and the device was formatted with ext4. After getting the master/master setup to work I simply reformatted the device using ocfs2. I reinitialized the device completely using the commands Both nodes drbdadm create-md r2 drbdadm attach r2 drbdadm syncer r2 Second node: drbdadm -- --discard-my-data connect r2 First node: drbdadm -- --overwrite-data-of-peer primary r2 drbdadm connect r2 Afterwards I formatted the device again using ocfs2. Let's see whether things are working reliably now...
