So, this is a software RAID?  Which device is /home on under 7.2?  From
your ks.cfg file, I'm guessing it's md3 (raid 05/raid 06).

I'm not at all certain you can do an upgrade from 7.2 to ES3 on software
RAID without reformatting.  First, that's one hell of a gear change
(jumping three major releases)  Second, the mechanisms used to support
software RAID changed quite a bit over that time.  I think you're going
to have to back up /home to some media somewhere and let the system
format /home to get past that.

Wish I could help more.
