With 3.16.3 kernel it seems to be stable but I've discovered one new issue.
If I take down one of the two osd node all the client stop to respond.
Here the output of ceph -s
ceph -s

When I take UP the node all clients resume to work.
Thanks,

Ok, I'll update kernel to 3.16.3 version and let you know.
Thanks,

Hi Lincoln,
I'm using the kernel client.
Kernel version is: 3.13.0-53-generic?
That's old by CephFS standards. It's likely that the issue you're seeing is
one of the known bugs (which were actually the motivation for adding the
warning message you're seeing).
