Description Glen 2005-09-21 20:39:57 UTC

User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Description of problem:
I've switched a couple nfs servers over to Red Hat Enterprise Linux 4, and now I've been noticing some strangeness.  At first I figured it was my older Fedora clients, but I get the same thing when I use RHEL 4 as the client.

What happens is that files seem to up and disappear from directories every so often.  For example I might type "ls", and it spits back the message "ls: .:No such file or directory", or some times a similar error for a file that resides in that directory.  Then, if I wait a few minutes ls lists the files as normal.

If it's any help, here's what an /etc/exports entry will typically look like:
/export/home/foo @trusted-servers(rw,no_root_squash,sync) @suspect-servers(rw,sync)

And here are the options I'm passing to the mount command on my clients:
-rw,bg,hard,intr,rsize=8192,wsize=8192

Version-Release number of selected component (if applicable):
kernel-smp-2.6.9-11.EL

How reproducible:
Sometimes

Steps to Reproduce:
1. Run ls in a directory inside an nfs share
2.
3.
  

Actual Results:  Sometimes ls acts strangely.

Expected Results:  I'd expect ls to just list files as normal.

This is almost certainly an instance of a problem already found and fixed; the
fix will be released as part of the U2 kernel.  Please reopen if the U2 kernel
does not solve the problem.

The patch we are using to fix this problem is attached to bug 150759.  For
