Re: fh_verify: permission failure (?)

[Darrell Michaud <dmichaud@xxxxxxxxxxx>]

I see this same problem with our test XFS / NFS server.

We're testing this setup:

SMP Linux kernel 2.4.6pre5-xfs (from CVS), compiled with kgcc

XFS volume on a software RAID 0 across two IBM 7200 75GB IDE disks 
shared via NFS

NFS (mostly v2, some v3) Clients using Irix 6.5.9m on SGI O2's.

We've seeing strange NFS behavior to any writeable exports. All clients 
can successfully mount the export filesystem and read from it. Not all 
clients can write to it, however, even though they all have identical 
access.

Some clients get a "access denied: read only filesystem" message when 
they try to touch new files or make new directies. They get this message 
repeatedly. Sometimes unmounting the nfs share and reloading the 
server's nfsd fixes this problem, but not always. Different clients have 
this problem on different days. It's quite annoying.

I was going to try either a different kernel version, or a simple scsi 
disk share (no software raid), and hope for better luck.

There is another NFS server in house that uses a 2.2.19 Linux kernel and 
ext2, and it does not have this problem with the same clients.
