Change Details

This will be the first time that we: * Have a mon running in a different subnet * Have a mon running bullseye (if we reimage) So we will want to be careful. The new IP would be (next free one in https://netbox.wikimedia.org/ipam/prefixes/553/ip-addresses/): ``` 10.64.149.20/24 ``` Things in puppet that might need changing: * hieradata/role/codfw/wmcs/openstack/eqiad1/backups.yaml * hieradata/eqiad/profile/cloudceph/mon.yaml We don't have either a cookbook to rebuild a mon, this might be a good opportunity to create it and test it (including adding functional tests).

This is not so simple, changing the IP of a mon is something **absolutely not recommended** by upstream: https://docs.ceph.com/en/latest/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address Investigating the best way to proceed.
