I'll do as soon as I can. I finish the migration of services running on the server so 
I can switch to the new server if it doesn't come back fine.....

No. Maybe I didn't explain clearly. I wondered if the fact that I used a 2.4.26 (with a different 
XFS version I gues) at a time could have changed the XFS partition in a problematic way 
(if it hadn't been unmounted cleanly eg).

I'll send an update when I have more info.
