I have a problem mounting GFS2 in my test setup:

I try to create a cluster with RHEL6.2 according to "Clusters from the 

I have cman with the proper cluster name "cluster".

cman starts without problems.

My cluster config is:

primitive resFS ocf:heartbeat:Filesystem \
	params device="/dev/sdb1" fstype="gfs2" directory="/mnt"
clone cloneFS resFS

Staring this on both cluster nodes work smooth.

But when I want st start this when only one node is available I get:

Aug 15 14:43:35 node1 kernel: dlm_new_lockspace error -512
Aug 15 14:43:35 node1 kernel: GFS2: fsid=: Trying to join cluster "lock_dlm", 
Aug 15 14:43:35 node1 kernel: dlm: Using TCP for communications
Aug 15 14:43:35 node1 dlm_controld[17757]: process_uevent online@ error -17 
errno 2
Aug 15 14:44:33 node kernel: dlm: store: group join failed -512 0

When I try to mount the FS manually

mount -t gfs2 -o locktable="cluster:store" /dev/sdb1 /mnt

I get a timeout.

Any ideas?
