[Pacemaker] After pacemaker is stopped on DC, it gets fenced because last 'stop' operation is lost

Tue Aug 16 10:21:09 CET 2011

Hi,

I recently discovered that when I stop pacemaker on DC node (for
upgrade), that node is shortly fenced by a new DC.

Fencing is caused by not-stopped (from the PoV of new DC) clone instance
(dlm in my case) which was actually stopped:

Aug 16 08:56:29 v03-a pengine: [2083]: WARN: custom_action: Action
dlm:2_stop_0 on mgmt01 is unrunnable (offline)
Aug 16 08:56:29 v03-a pengine: [2083]: WARN: custom_action: Marking node
mgmt01 unclean
Aug 16 08:56:29 v03-a pengine: [2083]: WARN: stage6: Scheduling Node
mgmt01 for STONITH

Actually, that stop op was correctly done:

Aug 16 08:56:09 mgmt01 pengine: [1465]: notice: LogActions: Stop

dlm stop is one of last operations (or very last) performed during
pacemaker shutdown, so I suspect that result of that operation is just
not propagated over the cluster. So right after lines above I see
following (sorry for many wrapped lines):

This is 100% reproducible in my setup, so I can take hb_report if this
is needed.
