I'm trying to join a new node into an existing 5 node CLVM cluster but I just can't get it to work.
When ever I add a new node (I put into the cluster.conf and reloaded with cman_tool version -r -S) I end up with situations like the new node wants to gain the quorum and starts to fence the existing pool master and appears to generate some sort of split cluster. Does it work at all, corosync and dlm do not know about the recently added node ?
