Hi Tao,<br>
<br>

<pre wrap=""> 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

-nodes2:

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.

<pre wrap=""><!---->Oh, so do you have enough slots for all these 3 nodes to mount?
What's the output for the below command?
echo 'stats'|debugfs.ocfs2 /dev/sdx|grep Slots

I've check that this node3"pings" successfully both other

<pre wrap=""> Hi,
I have a problem on Fedora13 with releases :
ocfs2 1.4.3-5.fc13.x86_64
dlm_tool 3.0.17
With a 3 nodes ocfs2 cluster, I can't mount FS on the three nodes at the same time
but only on two nodes among the 3 nodes , whatever the two nodes are among the 3 nodes.
The errors are :
"(1475,0):o2net_connect_expired:1656 ERROR: no connection established

It seems to be a lock management problem
Is it an already known issue ?
Is there an available patch ?

<pre wrap="">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 7777(which is used by ocfs2) of node 2 from
node 3.

Tao
