Hi All, I have question regarding Ceph Nautilus upgrade. In our test environment upgrading Luminous to Nautilus 14.2.8, and after enable msgr2, we seen one of the mon node restarted, my question is this normal process of restart mon service and 2nd question is, we using below mon_host format that can be correct or move to v2? mon_host = 10.44.172.181,10.44.172.182,10.44.172.183 Thanks, AmitG
