This is a Nautilus cluster.
ceph health reports everything is OK


Fetch the key from the OSD's datastore on the machine itself. On the OSD machine you'll find a file called keyring.

Get that file and import it with the proper caps back into cephx. Then all should be fixed!

The magic incantation there would be:

ceph auth add osd.<n> osd 'allow *' mon 'allow rwx' keyring
