[Linux-cluster] Nodes are getting Down while relocating service

[jose nuno neto]

Hello

Took a quick look on the messages and see no fence reference, there's a
break in token messages, recovering, cluster.conf change, comunication
lost again....
could be the service shutdown, after cluster.conf update, forcing shutdown

do you have drbd running too?

Cheers
Jose Neto
