If sda and sdb and if /boot is a mirrorred across the two drives then you need to in most cases hand edit grub so that it will boot from both drives. This is a very good right up on how to make a bootable mirrored pair of drives: http://grub.enbug.org/MirroringRAID. Also though I have not done a lot of benchmarking, you might want to consider moving to MD RAID10 instead of RAID1 as i am assuming that your are using the linux software raid. The MD RAID10 has the advantage of striping reads across the 2 drives, while RAID1 does its read in parallel. http://en.wikipedia.org/wiki/RAID http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
