Hi Josef,
I've patched one of our ceph nodes with the stuff in your master repo
(including lxo's patches).
The WARNING in inode.c seems to be gone now, but load is still going
up after a day.
Another thing I've witnessed is that I'm getting a new warning, when I
umount the filesystem (see below).
I just wanted to tell you, hoping that this gives you a hint what's going on.
Regards,
Christian
