Ok, it should not happen but sometimes it happens (specially 
during testing periods). A split-brain occured by one of my 4 test nodes.
(Network went down for a couple minutes and dead-time hit in and 
somehow the three other nodes managed to rejoin (or maybe never left
the group) but management1 failed to rejoin the cluster).

crm_mon shows me:

Node: routing2 (c5e1bda1-b00b-42e8-89e1-702b2d715c76): online
Node: routing1 (a98d68fb-807a-4b22-af3c-82e60064aa95): online
Node: management2 (a69b64a2-4de8-4d4a-b4ba-8107136eec4b): online
Node: management1 (0044b88e-c148-4269-9d39-449324bf65b8): OFFLINE

heartbeat is running on management 1 and the ha-log on that machine shows me:

crmd[1185]: 2006/10/31_13:22:42 WARN: do_dc_join_finalize:join_dc.c join-4: We are \

do_dc_join_finalize:join_dc.c join-4: We are still in a transition.  Delaying until \

Is there a "simple way" to tell node "management1" to rejoin the cluster without
shutting down heartbeat (rebooting) on that machine?

kind regards Max
