I can't assign Ceph Journal to single HDD.
UI blocks the "Apply" button and give warning that Ceph partiotion is too small.
But I don't need Ceph partition on that disk. I need Ceph Journal only
(see the screenshot)

Actually, I'm not suera that's a bug.. As far as I remember, it was implemented by design to deploy ceph on a separate partition.

[Dmitry Borodaenko (angdraug)]

According to the screenshot, the UI is complaining about Virtual Storage, not about Ceph. The fact that Virtual Storage is present in the list indicates that this is a ceph-osd + compute node, and Virtual Storage is needed for compute nodes. If my assumption is true, this bug is invalid. If it's a pure ceph-osd node without compute role, that's a real bug.

[Gleb (gleb-q)]

Dmitry, you are right.
I tested compute+ ceph on the same nodes and it's definitly about virtual storage.
Sorry for invonvenience
