Upgrade: It is NOT safe to stop mon.vx-rg23-rk65-u43-130 - ceph-users

2 Jun 2020

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.

Debug log:
