after trying to do this the filesystem locks up on the first node also.

Hi Dan,

So apparently it's the mount that's hanging, not clvmd.
By any chance, are you using manual fencing? Because I think this behavior
can be caused when a node is manually fenced, but the
fence_ack_manual script was never run.  If that's the problem, try:

fence_ack_manual -n <fenced_node>

Hey Robert,
thats right, its not really the clvmd but when starting as a service it performs a vgscan wich also freezes. Correct, I'm using manual fenceing for the moment, but I don't want to fence the other node since it hasn't faild, but to have the filesystem mounted by all the nodes at the same time. Just fence when it fails. Maybe I've missunderstood the possibility of this? Though I've used it on previous versions of centos.

Regards, Dan
