[Linux-cluster] HELP! Diapered block device

[Jon Scottorn]

Ok, so I am rerunning gfs_fsck again.  I have everything unmounted and
the storage server not even in the cluster.  It has been running now for
30 mins again and it gets to this point and just doesn't look like it is
doing anything.  This is where is stayed after running it for 24 hours
yesterday:  Here is what the verbose output from gfs_fsck:

Scanning filesystem for inodes containing duplicate blocks...

Once it gets to this point it just sits there.  gfs_fsck is using 99% of
the CPU for the whole time it runs.  What else can I do to get this fixed?

Thanks,

Jon
