Is iptables running on node3? If so, stop it.

   Hi,
The three cluster.conf are exactly the same on the 3 nodes.
The errors messages are :

Note that once a mount is refused for example on node3, if
I umount the FS on node1 for example, then I can mount it
on node3.
 

Oh, so do you have enough slots for all these 3 nodes to mount?

What's the output for the below command?

Note also that when the mound is refused for example on node3,
I've check that this node3"pings"  successfully both other
nodes on IP addr given in cluster.conf.

With a 3 nodes ocfs2 cluster, I can't mount FS on the three nodes at the same

It doesn't look like a dlm problem, but a network problem. ;)
So your first error is o2net_connect_expired.
So it seems that the 3rd node can't connect with node 2.
Could you please check the error message in node 2?

btw, I would deem that the cluster.conf is the same among the 3 nodes,
and you you can connect to (which is used by ocfs2) of node 2 from
node 3.

Hi,
The three cluster.conf are exactly the same on the 3 nodes.
The errors messages are :

-nodes1:
o2net: accepted connection from node selfxl-5 (num 1) at
10.197.189.218:
o2net: no longer connected to node selfxl-5 (num 1) at
10.197.189.218:

-nodes2:
(1457,1):o2net_connect_expired:1656 ERROR: no connection established
with node 1 after 30.0 seconds, giving up and returning errors.

Note that once a mount is refused for example on node3, if
I umount the FS on node1 for example, then I can mount it
on node3. 
Note also that when the mound is refused for example on node3, 
I've check that this node3 "pings" successfully both other

nodes on IP addr given in cluster.conf.
