[Pacemaker] Question about Dual Primary DRBD + OCFS2

[rvm at free.fr]

Hi and thanks for you answer.
Here my hb_report with 2 tests :
* node standby / node online = Inconsistent drbd (resolved by drbdadm verify or reboot of the node)
* ifdown / kill of dlm/corosync = instant reboot => I can't find any trace of this problem exept my screen dump.
I hope you'll see something interresting in my logs.

Thanks you again for your help,
Regards

We'd need a stack trace, that screen dump doesn't help much I'm afraid.
Try using hb_report to grab the logs etc.  It also includes backtraces
from any cores it finds.
