Not from Inktank, but here we go. When you add a OSD again it has to match the OSDs UUID as in the OSDMap. So when running mkfs for the OSD run it like this: $ ceph-osd -i <id> --mkfs --mkjournal --keyring /path/to/keyring --osd-uuid <uuid> You can find the UUID in the OSDMap: $ ceph osd dump|grep osd\.<id> At the end you'll find the UUID of that OSD. Without a matching UUID the OSD will refuse to start. The OSD stores it's UUID in the datadir in the 'fsid' file.
