According to this FAQ entry this is just by chance, they are not using
Atari partition tables (nor should they!) -

If you are not using partitioned disks you cannot expect parted to
properly identify the disk, even if it randomly works more often than
not. If someone is depending on this as a method for detecting Ceph or
not Ceph they need to find a better way.

My suggestion would be to use GPT partition tables and a ceph related
UUID for the partition type. Or names for the partitions.
