Hi,

I just caught unexpected fencing of a node because (as I see from a very
quick analysis, but I may be wrong) stonith resource running on it
(fence_ipmilan) failed to start and then stop.

Excerpt from logs:

I would expect stonith resources failures not to cause fencing. Am I wrong?

mgmt01 is running merge of latest ClusterLabs and beekhof trees
(ClusterLabs/pacemaker/master 98aca50 + beekhof/pacemaker/master
86b339c), v03-a was running 2518fd0 when that happened (I was rebooting
it in order to upgrade to the above version).

Sure, reason of the failure of the fence_ipmilan requires investigations
too, but that is not important for the above issue I think.
