[ClusterLabs] RGManager: no migration on kernel panic

[Stanislav Kopp]

Hi all,

I'm testing now "corosync+cman+rgmanager" on Debian Jessie (since
Pacemaker is not in repos), I'm running two nodes cluster with simple
VIP resource. Resource migration work pretty well if I gracefully
shutdown the active node, but if try to kill the node with simulated
kernel panic (echo c > /proc/sysrq-trigger) the VIP resource will not
be migrated even if "clustat" says the node is "offline". I've fome
some errors in fenced.log

"fence rgmanager02 dev 0.0 agent none result: error no method"

So if I understand it right, since fencing is not working rgmanager
does nothing in order to not make it worse, is that correct? If yes,
can I force it do not care about fencing? (I know that is general not
a good idea)

My cluster.conf for more information:
