action "debugfs-like" through nfs?

action "debugfs-like" through nfs?

[Rosario Turrisi]

Hi,
I have a fileserver from Raidtec which uses ext2 filesystems.
Due to a double (!!!) disk failure, I had the strange behaviour that
a directory is seen as a whole file, with strange attributes,
like "?r--r-sr-T" and changed owner/group.
I believe that an operation like "debugfs" could fix the problem,
but it cannot be done (it seems) on an nfs-mounted filesystem
(I cannot enter the fileserver system as it is "raidtec-copyrighted").
Any suggestion very very welcome.
Cheers,
       Rosario

Errr... Why is fixing it on the server itself (where "debugfs" is more
likely to work) not an option?

The NFS protocol has no support for doing low-level disk ioctls on the
server so you can forget doing this sort of thing on the client.

... because raidtec does not give the password to customers...
I am afraid, and you confirm, that the only choice is their  intervention...
Thanks,
