FW: Kickstart partition woes

[Gordon McDowall]

Thanks for the reply, to answer your questions, yes it's software raid and
yes /home was on md3, I cannot see why I should not be able to do this new
install since if you try a manual install then you can see all the
partitions and raid devices and the only thing that needs done is to relabel
the raid devices to reflect the partitions and tell it whether to format the
raid device or keep the data intact.

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.
