No need, restart by yourself.

No need to stop. Just upgrade osd server one by one and restart each osd daemons.

Hi,
I would like to upgrade my ceph cluster from hammer to infernalis.
I'm reading the upgrade notes, that I need to upgrade & restart the
monitors first, then the OSDs.
Now, my cluster has OSDs and Mons on the same hosts (I know that should
not be the case, but it is :( ).
I'm just wondering:
* Do the packages (Debian) restart the services upon upgrade?
In theory it should work this way:
* install / upgrade the new packages
* restart all mons
* stop OSD one by one and change the user accordingly.
Another question then:
Do I need to actually stop all OSDs, or can I upgrade them one by one?
I don't want to take the whole cluster down :(
Thanks very much,
udo.
