Maybe you have the same issue?
https://tracker.ceph.com/issues/44102#change-167531

In my case an update(?) disabled osd runlevels. 
systemctl is-enabled ceph-osd@0

Hi,

which ceph release are you using? You mention ceph-disk so your OSDs are 
not LVM based, I assume?

I've seen these messages a lot when testing in my virtual lab 
environment although I don't believe it's the cluster's fsid but the 
OSD's fsid that's in the error message (the OSDs have their own ID, too, 
take a look in /var/lib/ceph/osd/ceph-<ID>/fsid). When I did several 
re-installs of the whole cluster I had to make sure to properly wipe the 
disks but sometimes only a reboot did the trick. Of course, this is not 
an option in your situation.

If your OSDs are systemd units check for orphaned units that need to be 
to disabled before restarting the correct ones. Did you re-deploy some 
of those disks?

Regards,
Eugen
