No disk unused for ceph add osd

[Daniel Bidwell]

I have a system with an unused 480GB SSD as /dev/sdb. It has no partitions and I have zeroed the first 200MB of the drive. What do I need to do to it to make it a recognized available disk?

This is my first ceph osd in the system.

Many disks also have some backup partition table. Often its on the end or in the middle of the disk. In any case, destroy and create a GPT partition table to have the disk available in the GUI. The pveceph should be fine with the disk as is.
