What is the overall process of reinstalling (e.g., for going from
enterprise linux 7 to 8) and getting my OSDs back afterwards.

- reinstall operating system on system disk
- install cephadm binary
- ... now what? ;-)

You need to add the cephadm SHS public key to /root/.ssh/authorized_keys. After that you should be able to run

ceph cephadm osd activate $HOSTNAME

to have the orchestrator start the OSD containers on $HOSTNAME.
