This is FC SAN on QLogic HBAs.

Fencing normally works (e.g. when I manually reboot a node, it gets
restarted again after 10 seconds). With this problem showing up, fenced
is not interacting as far as I see it.

The cluster generally works well. Only if I increase the I/O load to a
certain level, the problems appear.
