[PLUG] Ninja repair of a XFS volume

[Julien Vehent <julien@linuxwall.info>]

Hi list,

One of my hosted server has some XFS problems. after the last crash, 
some of my RRD folders got corrupted.

example (sorry, it's in french):

---
# rm *
rm: impossible de supprimer « create_rrd.sh »: La structure a besoin 
d'un nettoyage
rm: impossible de supprimer « old »: est un dossier
rm: impossible de supprimer « tcgraph.log »: La structure a besoin d'un 
nettoyage
rm: impossible de supprimer « tcgraph.rrd »: La structure a besoin d'un 
nettoyage
---

The normal move would be to restart the system in single user, or using 
a live cd, and run a xfs_repair on /dev/sda.
Unfortunately (it would be too easy), the hosting company provides a 
option to restart on a live cd that doesn't work. Since the machine is 
hosted in France, and I'm in King of Prussia, visiting the datacenter is 
not an option.

It seems that I can't touch the inodes at all, I get that "structure 
needs a cleanup" message everytime.

So, question is: does anyone know a way to repair/fix that XFS 
filesystem by hand ?
Any low-level XFS manipulation tool that could help ?

Thanks,
Julien
