We found a kind of solution ourselves. We had caching values set in our ceph.conf. Apparently, this is what Ceph has become stricter about since version 18.2.7 or higher (we are now on 19.2.3). The startup checks have become more picky with this...

# mkdir /etc/systemd/system/ceph-mgr@.service.d
# cat...
Hi,
after running the latest apt dist-upgrade and rebooting one of our storage servers, all OSD's on this node refuse to start.

Any help appreciated :)
Setup: 7 x CEPH Storage...
