Description andrewz 2006-04-12 01:58:20 UTC
If /home is on NFS, then ltpfs fails with an error about a stale NFS handle. 
The attached patch mounts in /mnt/localdev and links ~/Drives to /mnt/localdev/$USER

I'd need more info to help with this.  I do know that ltspfs works just fine
mounting under NFS on Debian Sarge, and Ubuntu Breezy, as this is how I use it
at work.  Which NFS server are you running?  A userspace server, or kernelspace
server?  The kernelspace one ties in with VFS just fine, and should interact
with ltspfs no problem.

I use the systems' default NFS servers, and I assume those are kernelspace.  

NFS Server: Trustix 2.2, Linux 2.4
NFS Client: Fedora Core 5, Linux 2.16

Perhaps the problem is when I tested it, the NFS server did not having nfslock
running.  (Now nfslock is running, but right now, I don't have time to test.)

Hi Guys,

I have the same issue. If the users home dir is on NFS, we host our home folders
on a IBM AS/400 V5R3 system, then we get the following error "Unable to make the
fifo: Unknown error 524" but if the user's home dir is on the local system it
works great.

Thanks
Richard Houston

Turning on nfslock did not help, but enabling no_root_squash fixed the problem.
 However, no_root_squash is not always good, so I'm still hoping the patch (or
something like it) will be merged.

Also, I now believe my NFS servers are actually kernelspace.
