Hi Vitaly,

Most frequent use cases from disk config perspective are:

A) Ceph storage (dedicated nodes) - your approach works fine, nodes are
recommended to be uniform
B) LVM storage (dedicated or co-located w/ Compute nodes) - storage
configuration is per-node, your approach doesn't work
C) Enterprise SAN/NAS - disk config is mostly irrelevant

Leaving per-node configuration in CLI only is not good - it will limit
trial/pilot/playing around users. I would suggest exposing group
configuration on main screen with all nodes list as default option,
allowing individual node's config to be reachable via individual node's HW
screen.
