How to wipe a disk which was OSD before?

[sherminator]

Hi there,

I did a reinstall of my three node PVE/Ceph cluster, and now I would like to clean up the OSDs so that I can use them again as... OSDs . Lately I found a nice command for this task, but I can't find it anymore. Can you help?

Thanks and greets

I think I found it:

ceph-volume lvm zap /dev/sdX --destroy

Can you confirm that this is a clean way to start from zero?

Thanks and greets

The ceph-volume lvm zap /dev/sdX is enough, to clear the GPT. And with the pveceph the disk is then zapped again on creation.

sdX must be replaced by the "name" of your block device.
