Hello! I am novice in Ceph and I in the desperation. My problem in the fact that I cannot obtain keys from the nodes. I found similar problem in maillist (http://www.spinics.net/lists/ceph-users/msg03843.html), but me did not succeed in solving it. There Francesc Alted writes about the fact that " I tracked down my problem. It turned out that I was setting different names for the ceph servers in /etc/hosts than their own `hostname`." I rename all hostnames on all my nodes but it did not help. My admin server and nodes are: adm ceph-vm01 ceph-vm02 ceph-vm03 ceph-vm04 Below my ceph.conf, log and hosts file.
