Hi

I'm hamed.

We're using rook to deply a Ceph cluster. Rook periodically check empty disk and when it found one it prepare to be used as a ceph osd. Ceph uses Atari partition table to create bluestore for it osds.

The problem happens when they use parted to check if disk is partition or have a partition table.

They use the following command:

parted  --machine --script /dev/sdX print             

And the desired response should be this:

$parted  --machine --script /dev/sdX print            
BYT;
/dev/sdX:xxxxGB:scsi:512:4096:atari:xxxxxxx:;

But we get this output:

$parted  --machine --script /dev/sdX print            

BYT;
/dev/sdX:xxxxGB:scsi:512:4096:unknown:xxxxxx:;

Which is definitely wrong, as the output of blkid show the partition table is atari:

$blkid /dev/sdX

/dev/sdX: TYPE="ceph_bluestore" PTTYPE="atari"

We are using latest version of parted on ubuntu 20.04 with kernel 5.4.0-77:

$ parted -v
