Operation not permitted errors

[Dennis McEntire]

A few times when trying to copy a file into an xtreemfs mount, I get
an error "cp: writing `filename': Operation not permitted"

Then the file gets created and then is a zero byte size.

Trying to delete this empty file results in:

rm: remove regular empty file `filename'?

Hitting y and then enter just hangs the console and I have to close
the ssh session and go back in. Then the mount is hosed. Going back in
to the mounted directory works. CD into a sub directory works. But as
soon as I do an LS it fails and hangs the shell. Trying to umount and
remount:

umount: /home/xtreem: device is busy.
(In some cases useful information about processes that use the device
is found by lsof(8) or fuser(1))

It's really stuck. I found a couple LS processes and killed those, but
still no avail. Also, I did find a process for rm but am unable to
kill that one. I think that's what's keeping me from unmounting and
remounting the xtreemfs volume. I guess I'll bounce the box then.

=== UH OH ===

New update. Now the system is dead. Restarting the DIR and MRC box
killed things.

DIR and MRC seem to be running, no errors in the logs. But trying to
mount doesn't work:

Any ideas?

Hi Dennis,

It's hard to tell what the problem is without logfiles. If you can
reproduce the problem, please run the client with the following options
to enable some debug output:

mount.xtreemfs -f -d INFO server/volume /mnt/point &> client_log.txt

You can create an issue in our bug tracker on
http://code.google.com/p/xtreemfs/issues/list and attach the client and
server logs.
