Add an OSD on controller-0 for ceph:

system host-disk-list controller-0
system host-disk-list controller-0 | awk '/\/dev\/sdb/{print $2}' | xargs -i system host-stor-add controller-0 {}
system host-stor-list controller-0

There's only one hard disk so there's no /dev/sdb.

How to configure it?

Thanks a lot.
