Ok so i am tired of compiling packages on gentoo so with the great documentation i have arch installed almost. I have a
raid 1 for my boot drive and a raid 0 for my root (2 SSD's). I installed grub2 and am using metadata 0.90 to stay away from
any issues i decided. Ok, when i boot up i get the error "Unable to determine major/minor number root device UID ...."
I have browsed and browsed and i have no idea where to begin. New to Grub2. Im using a MBR and the install went fine.
heres : GRUB.CFG

paulb787, please edit your post.

AFAICT grub2 does not support partitioned raid0...there may be a workaround but it isn't well-described.
Prediction...This year will be a very odd year!

When I ran raid0 I just used a small /boot partition that wasn't in an array.
This wiki helped me figure it out https://wiki.archlinux.org/index.php/So … stallation
Don't forget this step, I think it's essential

Used the referenced command and have a partition id for the boot separate from the array partitions.
Refuses to boot in linux3.0

I wish I could be of more help lilsrecho but I no longer have an installation on Raid0. The minimal performance improvement didn't outweigh the increased difficulty in backing it up (Couldn't figure out how to do it with Clonezilla).
It is possible though so I'm sure you'll get it figured out.

Thanks for the comments...my use of raid0 is ongoing and I have no backups for any since the backups would fail as well in Linux3.0.
I have a two drive raid0 in kernel26 mode that runs very fast and boots fast even though kde4 is included in the array(not the DE however). Boots in 13 secs and with jumanji runs the internet in super-fast mode.
I find it advantageous using CF cards as pseudo SSD's. Had five in raid 0 but no longer do they boot in Linux kernel.

My boot partition is in a raid 1 my root is a raid0 this has worked for me in grub1 in gentoo. so is the problem the raid0 root partition? I could get rid of raid on the boot not to nessacary
