Hello Sage,
Thank you al lot for answering. Ideed this was the problem. But it was
strange as I told it booted from update without problems until the
ceph-disk command on boot.
I was updating from Ubuntu 14.04 so quite old ceph. Yes.
I posted what I did just in case another one has the same problem.
Thank you a lot.
