Hi,
i switched now debugging to ms = 10
when starting the dd i can see in the logs of osd:

And thats it, nothing more moves. And the dd is stuck.

On another osd's i can see:
2016-01-26 00:11:36.224232 7f9c18596700 0 -- 10.0.0.1:6804/51935 >>

c=0x21bc1760).accept replacing existing (lossy) channel (new one lossy=1)
So for me, this is some kind of bug.
Without loaded rbd/ceph kernel module ceph-fuse will not work.
