Can you share the following information?
- Kernel version
- Ceph version
- "ceph -s" output
The ceph filesystem is running on 3 debian wheezy boxes:

The machine that is trying to mount the filesystem is ubuntu 12.04

ceph version 0.47.2 (commit:8bf9fde89bd6ebc4b0645b2fe02dadb1c17ad372)
Did not see this when running everything on ceph 0.46, so I will try to
upgrade the debian boxes.
The MDS / POSIX filesystem hasn't been tested very well at the moment,
in the next sprint (starting soon) the developers will start focusing on
the POSIX filesystem.
That's good news. Thanks a lot!
