I recently acquired a 7TB Xserve RAID. It is configured in hardware as 2 RAID 5 arrays of 3TB each. Now I'm trying to configure a RAID 0 over these 2 drives (so RAID 50 in total). I only wanted to make 1 large partition on each array, so I used parted as follows: parted /dev/sd[bc] (parted) mklabel gpt (parted) mkpart primary 0 3000600 (parted) set 1 raid on (parted) q for each of the disks. Then I went to go make the RAID array: mdadm -C -l 0 --raid-devices=2 /dev/md0 /dev/sdb1 /dev/sdc1 Everything seems ok at this point, /etc/mdstat lists the array as active.. I then wanted to put LVM on top of this for future expansion: pvcreate /dev/md0 vgcreate imagery /dev/md0 lvcreate -l xxxxxxx -n image1 imagery (xxxxx is the number of PEs for the whole disk, couldn't remember the number off the top of my head) then a filesystem.. mkfs.xfs /dev/imagery/image1 Everything works fine up to this point until I reboot. after reboot, the md array does not reassemble itself, and manually doing it results in: mdadm -A /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdb1: no RAID superblock Kernel is 2.6.14 mdadm is 1.12.0 Did I miss a partitioning step here (or do something else sufficiently stupid)? Thanks in advance, and please CC me for I am not subscribed. -- James - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
