Thank you for taking your time thanis, and others who reading this reply right now! I've followed your how to (step for step) again and again with a new installation on both servers. But whatever I do after a reboot of the two servers drbd0 isn't mounted. Not even when I run /etc/init.d/drbd stop/start/restart.
When I try to mount it again (mount -t ext3 /dev/drbd0 /var/vm) I get the following: mount: block device /dev/drbd0 is write-protected, mounting read-only mount: /dev/drbd0 already mounted or /var/vm busy
I have no idea what I'm doing wrong, I hope you do!!
