Hi All, I am trying to upgrade ceph 15.2.1 to 15.2.3. I've two node setup on small environment for test only. I ran the following commands: $ ceph mon ok-to-stop mon.vx-rg23-rk65-u43-130
quorum should be preserved (vx-rg23-rk65-u43-130,vx-rg23-rk65-u43-130-1) after stopping [mon.vx-rg23-rk65-u43-130]
$ ceph orch upgrade start --ceph-version 15.2.3 However, Ceph says it is NOT safe to stop mon.vx-rg23-rk65-u43-130.
