CentOS - Jan 2013 - Share GFS2 partition freezes when new node add in the cluster

Hi all.

I need support about GFS2 and RHCS.

Actually I have cman cluster formed by 9 nodes.

All works whitout problems but when I try to include a new node in the
cluster I must reboot all nodes because share partition GFS2 freezes. 

cman_tool status not show "Blocked activity" in each node and in logs
all apears normally whitout any WARNING or ERROR in /var/log/cluster/*


I have not found solution about this and I'm desperate.


Any ideas?


Thanks in advance
