Are they LVM based?
The keyring files should be just the filenames, yes.
Here's a recent list I saw which was missing the keyring step but is
reported to be complete otherwise.
- Stop RGW services
- Set the flags (noout,norecover,norebalance,nobackfill,nodown,pause)
- Stop OSD/MGR/MON services
- Moves the folder under /var/lib/ceph/mon/<old cluster name> into
the the <new cluster name >
- Moves the folder under /var/lib/ceph/mgr/<old cluster name> into
the the <new cluster name >
- Copies the .conf and keyrings with the new cluster name
- Edits systemd unit files for MON and MGR to reflect the new cluster
name at CLUSTER env variable
- Edits /usr/share/ceph-osd-run.sh file to reflect the new cluster
name at CLUSTER env variable
- Changes the lvm tag to the new cluster name for all OSD LVs
- Reloads the systemd daemon
- Starts the MON/MGR/OSD services
- Unset the flags
- Starts the RGW service
