Hello,
I have some trouble gettins drbd to sync properly, it run for some
days good, but than the server rebootet,
we dont know why jet and i cant get my second drbdb device to go into
primary/secondary mode

Im also using heartbeat to do a failover, can there be the problem?
I not 100% sure if the failover will work, i always errors about the
ucast device is not up.

This is the output of /proc/drbd, i tried to disable and connect he
2nd device, but it goes standalone after 2 seconds.
