Wait, let me get this straight- you have 6 drives, and you're using RAID level 1 through LVM? You know what that means, right? You've just lost 5 disks worth of space. Why not just give the 5 disks to me? I could put them to good use. :) Unless you need that extreme redundancy, I would suggest starting over using Linux software RAID beneath LVM. With 6 drives, I would do RAID level 6 with all active in the array. Then, you're utilizing a decent amount of disk space for your 6 drives, and should a drive fail, you'll deprecate to RAID 5, which works well. Just a thought. -- . O . O . O . . O O . . . O . . . O .
