No LVM over the two RAID 1's is more like RAID 1c which is just a concatenation of RAID 1's. You don't get the striping that you get in RAID 10. -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Ruslan Sivak Sent: Friday, May 04, 2007 11:22 AM To: linux-raid@xxxxxxxxxxxxxxx Subject: raid10 on centos 5 I am trying to set up raid 10 and so far with no luck. I have 4 drives, and Anaconda will not let me do raid 10. mdadm doesn't have the raid 10 personality loaded. When I create the array manually like so: 2 drives in /dev/md11 as raid1 2 drives in /dev/md12 as raid1 md11 and md12 in /dev/md10 as raid0 Everything looks fine from the shell, but anaconda only sees md11 and md12. The only choice I see is to set up LVM over md11 and md12. Is this really raid10?
