Bug#599823: NFS duplicate filenames



Title: Re: NFS duplicate filenames
No registration for Debian tickets - just send an email to 599823@bugs.Debian.org  -- I've CC'd this email to the ticket so it can be part of the tracking

So this might be a client side issue that dates back quite a way..

I'm going to see if I can test on some older kernels.

So far we've seen it on:

Debian: 2.6.36-rc6-686-bigmem
Fedora: 2.6.34.7-56.fc13.x86_64
Ubuntu: 2.6.32-22-generic

Regards,
Jason

I’m not registered on the Ubuntu support site, I found your issue via google.

Damnit.. That means its no longer my Drobo causing the issue.

Could you layout the clients with kernel versions please? I'd like to go back to tracking this down. Maybe send it to me and the ticket. Your the first person to come forward with the same issue.

Varies actually, we’ve seen it on Fedora 13 clients connecting to a CentOS 5.5 server via nfsv4 and those same clients connecting to RHEL 5.5 server via nfsv3

Did you ever find an answer for this issue?  I'm running into the same thing on Fedora 13 and yours is the only report of it I've seen.  Same situation, I have an incoming directory with thousands of files that users attempt to mv, resulting in duplicate filenames showing up then disappearing eventually on their own.  One difference I've seen is that if I mv/rename a file, it is listed singular, but if I rename it back, it's once again duplicate, at least temporarily.

If you got any further diagnosis or answers on this, I'd appreciate any info you have.
