Cannot create CEPH OSD

[impire]

Hello,

I hope someone could help.

I tried to create the OSD for Ceph, it doesn't let me. It doesn't see the disks even the disk are display in the DISKS section.

I also see an OSD already created for one of the disks but I never created one. I have 3 nodes. All 3 behaving same.

Attached are picture for reference. Any help would be much appreciated. Thank you.

This is because Ceph requires the full, bare disk. Your disks contain partitions which seem to be in use already. You will have to format the drives, before using them with Ceph.

I am unsure where this came from, if not from you, but if you like, you can remove it you remove, destroy and zap it (all relevant info is in section 8.5 of the PVE admin guide [1].
