NOW 10.7.3 Raid0 SSD, yes, finally I got it!
First Off, This Forum Rocks! After an evening of tinkering I now have Lion 10.7.3 running in Raid0 on two corsair SSD's.
I installed a little differently and I think I should share....however this is a very quick down & dirty run thru....not for the faint hearted.
Step 1. Prepare working copy of 10.7.3 on separate HD from raid hd's
-In my case I had Chimera setup with options to boot Win7/linux on the same HD(in diff partitions). Chimera boot loader w/options will still work in raid0 array after this install.
-Finalize any additional tweaks, kext edits, etc. for Lion 10.7.3 partition.
Step 2. Prepare SSD's in Raid0 from within existing lion partition.
-write down/copy/screen-capture UUID of raid array
Step 3. Use Carbon Copy Cloner to Clone 10.7.3 onto newly created raid array.
Step 4. Follow Neilhart's steps on pg 1. section 2 (THANK YOU neilhart!)
-Copy /Extra's folder to Desktop, modify boot.plist for kernel cache/RAID UUID strings
-Use Fdisk, DD, CP commands to prepare/move boot0 & extra's on disk(s) partitions
Step 5. modify "com.apple.Boot.plist" by adding key/string for UUID of raid array.
-This is very similar to Coupz post located bottom pg 4 (Thank you Coupz!)
-I had to unmount then mount raid0 array not individual partitions...
-find: com.apple.boot.S/Library/Preferences/SystemConfiguration/com.apple.Boot.plist file
-Copy to desktop and add UUID string same as Coupz post.
-enable Super User Do in separate command line: sudo su
-Go to that same directory/folder and replace the com.apple.Boot.plist file with the one you just modified. I simply busted out some nasty command line kung-Fu but you could also simply drag and drop these locations/files into the command line....WA POW!
-Lion will prompt you to over-ride this file/admin password, do it!
Step 6. Ensure that your raid0 array is first in mb boot priority.
Step 7. Test to ensure you can use Chimera "F10" to load either win7, linux, or newly created Lion 10.7.3(Raid). If you have all that... If all goes well you can now delete the previous 10.7.3 non-Raid partition.
Hope this helps anyone who had issues w/10.7.3 Raid0.
-Enjoy!
