It's only listening on v2 because the mon map says so. How it got into the mon map like this is hard to guess, but that's the place where you have to fix it. Simplest way to change the IP of a mon is destroy and re-create, but you can also edit the monmap manually following these instructions: https://docs.ceph.com/docs/octopus/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address-the-messy-way Specify both v1/v2 addresses explicitly using the same syntax as you've used in the config file. Speaking of your config file: your mon_host config line is unnecessarily complex, trying both v1 and v2 is the default. You can simply write it like this if you are running on the default ports: mon_host = 10.144.0.2, 10.144.0.3, 10.144.0.4 This has the advantage of being backwards-compatible with old clients.
