Hi Clay,
This can be accomplished at runtime if done right,
take a look at this thread I opened a while ago.
https://forum.proxmox.com/threads/ceph-changing-public-network.119116/
In the meantime other users did such a migration succesfully including myself.
Kind regards
David der Nederlanden

I have Promox and Ceph running on 5 servers.
I currently have 2 NICs in each server, a 1Gb NIC that's configured as the
Ceph "public network", 192.168.75.0/24; and a 2.5Gb NIC that's configured as
the Ceph "cluster network, 192.168.70.0/24. The .75 net is also what
connects the servers to the "rest of the world", including some Synology NAS
servers.
I have a 1Tb SSD drive on 4 of the 5 servers configured as Ceph OSDs.
I'd like to get better performance out of Ceph, so I added a 3rd 2Gb NIC to
each server, 192.168.71.0/24.
I took down all my VMs; and in ceph.conf, changed the mon entries and the
public_network entries from 192.168.75.xx to 192.168.71.xx; then did a
"restart ceph-target" on each of the Proxmox servers.
That was a complete disaster! Ceph never came back up and I had to reverse
the process in order to restore.
Is there a "correct" way to do this; or did I just miss a step. Is there a
config file for the OSDs that I need to change?
Thanks in advance!
