The documentation very briefly explains a few core commands for restarting things; https://docs.ceph.com/en/quincy/cephadm/operations/#starting-and-stopping-da... but I feel I'm lacking quite some details of what is safe to do. I have a system in production, clusters connected via CephFS and some shared block devices. We would like to restart some things due to some new network configurations. Going daemon by daemon would take forever, so I'm curious as to what happens if one tries the command; ceph orch restart osd Will that try to be smart and just restart a few at a time to keep things up and available. Or will it just trigger a restart everywhere simultaneously. I guess in my current scenario, restarting one host at the time makes most sense, with a systemctl restart ceph-{fsid}.target and then checking that "ceph -s" says OK before proceeding to the next host, but I'm still curious as to what the "ceph orch restart xxx" command would do (but not enough to try it out in production) Best regards, Mikael Chalmers University of Technology
