Hi,
this was the hint to the right direction.
root@ceph03:~# initctl list |grep ceph
ceph-mon (ceph/ceph03) start/running, process 1266
ceph-osd (ceph/4) start/running, process 1593
and
root@ceph03:~# stop ceph-mon id=ceph03
ceph-mon stop/waiting
did the trick. :)
to start the mon again: root@ceph03:~# start ceph-mon id=ceph03
Many thanks for your help!
Mit freundlichen Grüßen / Best Regards,
