Hi! How/where can i change the image configured for a service?
I tried to modify /var/lib/ceph/<fsid>/<service_name>/unit.{image,run}
but after restarting
ceph orch ps shows that the service use the same old image.

Hi Adrian,

Hi!

Try “ceph config set <target> container_image <your image>” where <target> can be global, osd, osd.1, etc. Then redeploy

yup, i did

it with “ceph orch” series commands.

well, already tried .. unfortunately because this is a test "cluster" on my 
desktop
i have a single mgr, and it seems that there is a requirement of having a 
second standby mgr.

i tried to start a second mgr, but because of listening port clash i can't... 
and i see not such option
in ceph config show

so, i was hopping to be able to make the service (podman) to restart with the 
new image ..
and no joy so far ..

Thanks a lot!
Adrian

What other configuration locations are there for the ceph components
beside /etc/ceph (which is quite sparse) and /var/lib/ceph/<fsid> ?

Monitor configuration database.
