| Only, with different inodes each time.
| 
| After that event, services running on that filesystem are marked
| failed and
| not moved over another node. Any access to that fs yields I/O error.
| Server
| needed to be rebooted to properly work again.
| 
| I did ran a fsck last night on that filesystem, and it did find some
| errors,
| but nothing serious. Lots (realy lots) of those :
| 
| Ondisk and fsck bitmaps differ at block 5771602 (0x581152)
| Ondisk status is 1 (Data) but FSCK thinks it should be 0 (Free)
| Metadata type is 0 (free)
| Fix bitmap for block 5771602 (0x581152) ? (y/n)
| 
| And after completing the fsck, I started back some services, and I got
| the
| same error on another filesystem that is practily empty and used for
| small
| utilities used troughout the cluster...
| 
| What should I do to find the source of this problem ?

Hi,

I believe this is a GFS2 bug we've already solved.
Please contact Red Hat Support.
