...but is there a good way to arrange for cephadm to use the
already-downloaded image without having to remember to specify --image
each time?
You could create a shell alias:
alias cephshell="cephadm --image docker-registry.wikimedia.org/ceph shell"
* OS reimages
We do OS upgrades by reimaging the server (which doesn't touch the
storage disks); on an old-style deployment you could then use
ceph-volume to re-start the OSDs and away you went; how does one do this
in a cephadm cluster?
[I presume involves telling cephadm to download a new image for podman
to use and suchlike]
cephadm osd activate HOST
would re-activate the OSDs. Before doing maintenance on a host run
ceph orch host maintenance enter HOST
and the orchestrator will stop the OSDs and set them to noout and will
try to move other services away from the host if possible.
