Ummm, there is NO mirroring in RAID 5.

No. LVM is at a completely separate (and "higher) level than the h/w RAID controller. > Do I need to do anything specific when creating a LV? I plan on striping > my LV to create extra spindles.

The tenor of your questions and comments indicates that you *really* need to learn more about the different types of RAID. If you want: - - best R/W speed and no redundancy, use RAID 0 (striping), - - best R/W speed, full redundancy, use RAID 10 or RAID 0+1. - - worst W speed, great R speed and low "RAID overhead", use RAID 5. - -- Ron Johnson, Jr. Jefferson LA USA "Kittens give Morbo gas.
