Hi, Using ceph-volume is absolutely *NOT* mandatory, this is only a way to setup your ceph cluster, but that's really not the only one.
I've been using ceph-osd without it, and the ceph-osd@.service is really enough, provided that you know how to set it up properly. Therefore, this bug is *NOT* of severity grave, because the definition is: "makes the package in question unusable by most or all users, or causes data loss, or introduces a security hole allowing access to the accounts of users who use the package." There's no security hole or data loss, it is just maybe a little harder to use ceph-osd. It would still be desirable to get this fixed ASAP though, and probably deserving a fix before Buster is out.
