I have some problem with adding a new mon to existing ceph cluster.
Now cluster contains a 3 mon's, but i started with only one in one

OSD. Adding, a new OSD is quiet simple, but adding, a new mon is

Maybe i missunderstood problem, but i see something like this.
My setup is 3 node cluster. 78 osd and 3 mons. At the top of the
