Hi, I have recently add a new host to ceph and copied /etc/ceph directory to the new host. When I execute the simple ceph command as "ceph -s", get the following error.

When I looked at the syslog on the ceph cluster node, I saw that message too.

Anyone can help me out or assist to the right direction or link?

Hi Cem, I take it that you upgraded to one of 14.2.20, 15.2.11 or 16.2.1 releases and then set auth_allow_insecure_global_id_reclaim to false? What version of ceph-common package is installed on that host? What is the output of "ceph -v"? Thanks, Ilya
