[Ocfs2-users] Pb with ocfs2 & dlm on Fedora 13

[Alain.Moulle]

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
10.197.189.218:7777
o2net: no longer connected to node selfxl-5 (num 1) at
10.197.189.218:7777

-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.

Alain
