Q: Mountain Lion Upgrade with Raid1
I have a Mac Mini OSX Server with a pair of 500 Gig drives in RAID1 as my system partition. The 10.8 install off a bootable USB drive hangs as it's looking for recovery partition to be created if one doesn't exist which in my case it doesn't as the recovery parition is not supported on RAID. When I run the installer inside Lion it gives me a warning:
"Some features of Mac OS X Lion are not supported for the disk, Features such as Filevault and Recovery Mode won't be available etc.."

When I acknowledge the error, the server reboots back into Lion as if the installer never ran. I'm a bit stumped as to how to get my server upgraded to Mountain Lion without doing a fresh install... any advice?
Thanks in advance

Figured out the problem. I was running the installer from a DMG file I pulled down on a different Mac. The server log was showing a problem when it rebooted that it couldn't re-mount the Volume that the ML install was on which is why it booted back into Lion. To fix it I basically opened up the app store and redownloaded the file from there and ran the installer from the Applications menu and it went through.
So to sum it up, if your installing ML on a Lion server with a RAID system volume, just run the app store download and install it from there, don't try to install it via DMG mount or bootable DVD/USB.
