[Gluster-devel] ESTALE / "Stale NFS file handle"

[Dan Parsons]

I'm getting the below error messages in rc4. Like my previous email, there
doesn't seem to be any pattern as to which server/client it's happening on,
though the errors are occurring fairly frequently.
2009-03-09 17:32:26 E [unify.c:585:unify_lookup] unify: returning ESTALE for

As you can see, there are two separate sets of errors for two different
files, though both errors are troubling. This problem has persisted from rc2
to rc4, though I can't say for certain that it was introduced in rc2 (I
think it was there prior to that as well). No matching errors in server
logs.

Any suggestions? My configs are below. Thanks!
