ceph-disk or ceph-volume ?

[Alex_HH]

today I added some new HDDs to our storage nodes. All HDDs are Seagate IronWolf 8TB.
As you see attached, the new HDDs are shown with a different size.
Only difference I know is I created the old OSD with cep-volume by myself, not within the GUI.

I used cep-volume because cep-disk is deprecated ( http://docs.ceph.com/docs/mimic/ceph-volume/ )

Is the GUI still using ceph-disk to create the OSD?

In the Mimic release, yes. PVE uses Luminous and it still uses ceph-disk.

Old thread, hopefully this is informational to others:

Hard disk manufacturers correctly use the term Tera Bytes, eg 8TB which is 8,000,000,000,000 bytes. The storage term everyone else has miss used, is a multiple of 2 and called Tebi Bytes (TiB).

8 TB = 8,000,000,000,000
/ 1024 / 1024 / 1024 / 1024 = 7.276 TiB
