Please push this into the logger

Changes are in-progress

[PraveenPenguin]

if we have given single disk is this work?

[priyama2]

When single disk, as of now install fails, since raid requires at least 2 disks.
As discussed if user specifies one disk then it will be considered as default 'plain' mode of install
Changes are in-progress.
