I've currently got the machine running stand alone (no network connections). I have changed the hard drives just in case with no change. I have also moved drives around so that there is a diffent drive running as hdc instaed of hde, again the same error occours. Adding more (smaller) partitions gives the same result. One thing I have found is that /dev/drbd0 was missing, but on the other, working machine it was created presumably when I installed drdb etc. Perhaps the installation was messedup in some way. The only other thing I can think of is that Centos is reporting the drive as being mounted when it isn't. Rob
