I did some more research by running a fsck -fn. Basically it is one
inode that is wrong and needs to be cleared. Is there a way to do
that via debugfs? If I can delete that one inode, then all the
doubly-linked clusters will not be doubly linked any more and all of
the errors will go away.<br>
<br>
Isn't that quicker than cloning a bad inode?<br>

<br>
I am running a two-node Oracle VM Server 2.2.2
installation. We were having some strange problems
creating new virtual machines, so I shut down the systems
and unmounted the OVS Repository (ocfs2 file system on
Equallogic equipment).<br>
<br>
I ran a fsck -y first, which replayed the logs and said
all was clean. But, I am pretty sure there are other
issues, so I started an fsck -fy<br>
<br>
One of the messages I got was:<br>
<br>
Cluster 161213953 is claimed by the following inodes:<br>
<76289548><br>
/running_pool/450_gebidb/System.img<br>
[DUP_CLUSTERS_CLONE] Inode "(null)" may be cloned or
deleted to break the claim it has on its clusters. Clone
inode "(null)" to break claims on clusters it shares with
other inodes? y<br>
<br>
I then watched with an strace -p <fsck process> to
see what was happening, since it was taking a long time
with no messages. I see:<br>

<br>
This is going on and on. It looks like it is writing lots
of entries to fix one duplicate inode???<br>
<br>
At this point, I have aborted the fsck, as I am worried
that it is completely trashing our OVS repository disk.<br>
<br>
Can anybody shed some light on this before I restart the
fsck? We need to be back up and running ASAP!<br>
<br>
Thanks in advance!<span class="HOEnZb"><font
