Hello, is it possible or will it be possible to use dev-mapper devices within devmapper tables (recursion) ? (for software raid 1+0, 5+0 or 5+1 etc.) Example: A stripe over mirrored disks (raid 1+0) as: m = size of physical disk n = size of LV table_mirr_1: 0-m mirror /dev/sda1 0 /dev/sdb1 0 table_mirr_2: 0-m mirror /dev/sdc1 0 /dev/sdd1 0 table_stripe: 0-n/2 linear /dev/device-mapper/mirr_1 n/2+1-n linear /dev/device-mapper/mirr_2 Thanks, Robert Heinzmann
