Changing tagline to something more descriptive...

Patch in description looks sane -- have you actually tested it? Can you give a
bit more detail on how to reproduce this? When I do a ls in nfsv4 directory it
works fine for me...

Comment 3 Brian Pontz 2007-11-05 17:55:42 UTC

We have a couple of nfs servers. One of them I'm trying to change from NFSV3 to
NFSV4. I made the exports to look like

/data/sptemps           *(rw,fsid=0,insecure,no_subtree_check,async)
/data/sptemps/sptemp2   *(rw,insecure,no_subtree_check,async,nohide)


automount options are
-fstype=nfs4,rw,rsize=8192,wsize=8192,timeo=600,retrans=6

for some reason we get the error stated above after the mount and we do a "ls".
We have a RHEL 5 nfs server setup like this RHEL 4.5 one but it doesnt have
these issues when using the same options and same clients.

Let me know if you need more info.  I havent tried the patch I pointed to earlier.

I've posted some test kernels with this patch on my people page:

http://people.redhat.com/jlayton

..could you test them and confirm that the problem is resolved?
