Hi,

I have configured two machines for testing gfs filesystems. They are
attached to a iscsi device and centos versions are:
CentOS release 5.4 (Final)
Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009
i686 i686 i386 GNU/Linux

The problem is if I try to mount a gfs partition it hangs.

[root at node2 ~]#  cman_tool status
Version: 6.2.0
Config Version: 29
Cluster Name: gfs-test
Cluster Id: 25790
Cluster Member: Yes
Cluster Generation: 4156
Membership state: Cluster-Member
Nodes: 2
Expected votes: 2
Quorum device votes: 2
Total votes: 4

Node name: node2.fib.upc.es
Node ID: 2
Multicast addresses: 239.192.100.35
Node addresses: 147.83.41.130

[root at node2 ~]# cman_tool nodes
Node  Sts   Inc   Joined               Name

   1   M   4156   2010-03-24 17:08:36  node1.fib.upc.es
   2   M   4132   2010-03-24 14:46:09  node2.fib.upc.es

[root at node2 ~]# group_tool
hangs...

[root at node1 ~]# mount -t gfs /dev/home2/home2 /home2
hangs...

If I cancel the command I can return to the terminal and I don't see
anything in log files.
The resource /dev/home2/home2 is accessible by the two nodes and if I
try to mount /home2 with lock_nolock there is no problem.

cluster.conf is:

</cluster>

Any help will be welcomed.
Thanks,
