I think you are not understanding what drbd does.
It is network RAID1 ... you can't mount and use the DRBD device on
both
machines at the same time. It is designed so that if the first
machine
fails, the second machine / partition is used instead.
Jonny,
Thanks for the info. I understand that point. However, with DRBD not running or mounted on shorty, Fs1 still gives the same error.
You are correct. The "lower device" in this message is the physical disk. Specifically, /dev/hde1 (as configured).
I have no idea why you are getting this message, but that Invalid Argument error doesn't look to good for me.

Thanks Rodrigo,
I'm still having problems with this. 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.
