Clueless Sys Admin here...
I have no idea how to trace this. But I can duplicate it pretty easily... Here's what I have:
Kernel Version: 2.6.29.3 Vanilla with drbd-8.3.1 module built against that source.
Systems runs heartbeat v.1 to manage drbd fallover.
Both systems run identical hardware.
Crash occurs when a system is moving from primary to standby.
Appears to crash when drbd xfs file system is unmounted.
System never responds to more then a ping after crash.
Functions flawlessly running on 2.6.28.9
Here is the "cut here" stuff:
