Hi,<br>
I'm using ocfs2 cluster in a production environment since almost 1
year. During this time i had to run a fsck.ocfs2 few months ago due
to some errors but they were fixed.<br>
Now i have a big problem: I'm not able to mount the volume on any of
the nodes. I stopped all nodes except one. Some output bellow:<br>
<b>mount /mnt/ocfs2</b><b><br>
</b><b>mount.ocfs2: I/O error on channel while trying to determine
heartbeat information</b><b><br>
</b><b><br>
</b><b>fsck.ocfs2 /dev/mapper/volgr1-lvol0</b><b><br>
</b><b>fsck.ocfs2 1.6.3</b><b><br>
</b><b>fsck.ocfs2: I/O error on channel while initializing the DLM</b><b><br>
</b><b><br>
</b><b>fsck.ocfs2 -n /dev/mapper/volgr1-lvol0</b><b><br>
</b><b>fsck.ocfs2 1.6.3</b><b><br>

<br>
<br>
Can you give me some hints on how to debug the problem?<br>
<br>
Thank you,<br>
Laurentiu.<br>
