Hi,

we've fixed the problem.

We configured our hostname in /etc/hostname to "px1.cluster.local",
"px2.cluster.local" and "px3.cluster.local".

It seems that DRBD won't work with a FQDN in /etc/hostname - as we changed
it to the short name like px1, px2 and px3 and rebooted, everything worked
immediately. This is strange and I think it's a bug in DRBD, huh?

Mit freundlichen Grüßen,

Dominic Pratt
