Hello,
I had OSD 23 on one of my hosts but the drive failed so we stopped the services and removed it. We did not need to replace it immediately (lots of OSDs in the cluster so not a lot of capacity lost) so I didn't pay much attention to it...
I wanted to set up the same and discovered what is wrong here... I think the Proxmox Team has not adjusted the package to work with their management of ceph and this is the bone-stock default file paths/service names it is trying to use.
It is...
