a cluster has ms_bind_msgr1 set to false in the config database.

Newly created MONs still listen on port 6789 and add themselves as providing messenger v1 into the monmap.

How do I change that?

Shouldn't the MONs use the config for ms_bind_msgr1?

This config setting for listen, not for a "new mon born" To disable msgr1 for mon completely, you should run command "ceph mon dump", and then use the v2 address and mon name as arg for a command, like this: `ceph mon set-addrs mon1 v2:10.10.10.1:3300` This will set only v2 address for your new mon k
