According to this FAQ entry this is just by chance, they are not using Atari partition tables (nor should they!) - https://rook.io/docs/rook/v1.6/ceph-common-issues.html#unexpected-partitions-created > The problem happens when they use parted to check if disk is partition or > have a partition table. 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. Brian -- Brian C.
