[Gluster-users] Weird Glusterfs problem

Hello Gluster gurus,

I'm experimenting with Gluster and I've run across a problem that I
don't understand.

I have Ubuntu 12.04 with Gluster 3.2.5.  I created a volume and filled
it with data.  Then I left an rm -fr going to wipe it out over night. 
When I came in this morning, I found a lot of stuff like this:

rm: cannot remove `old/old.5/test-host/20130707/etc/init.d/apport':
Stale NFS file handle

The log file data-testvol.log shows:

[2013-07-09 10:13:37.229796] W [stat-prefetch.c:2632:sp_unlink_helper]
0-testvol-stat-prefetch: lookup-behind has failed for path
(/old/old.5/test-host/20130707/etc/init.d/apport)(Stale NFS file
handle), unwinding unlink call waiting on it

0-glusterfs-fuse: 105965: UNLINK()
/old/old.5/test-host/20130707/etc/init.d/apport => -1 (Stale NFS file

The interesting thing is that if I delete
old/old.5/test-host/20130707/etc/init.d/apport by hand, it works:

root at gluster-server-a:/data/testvol# cd
root at gluster-server-a:/data/testvol/old/old.5/test-host/20130707/etc/init.d#
rm apport

This seems to have worked for files, and for some directories.  But for
other directories there's still a problem.  Gluster seems to think that
some directories are not empty, even though there is nothing inside:

root at gluster-server-a:/data/testvol/old/old.5/[...stuff...]/Maildir# ls -al
total 72
drwxr-xrwx 3 root root 16384 Jul  8 23:46 .

-fr .Old\ Mail.Mailbox12092004_end/
rm: cannot remove `.Old Mail.Mailbox12092004_end': Directory not empty

Next I rebooted every node in the cluster.  The problem persists.

Anyone have an idea what's going on?  Or how to fix it?
