Hmmm. I didn't think it was possible, but evidentally it is; according to the md(4) man page: : KERNEL PARAMETERS : The md driver recognised several different kernel parameters. : : raid=partitionable : : raid=part : : These are available in 2.6 and later kernels only. They indicate that : autodetected MD arrays should be created as partitionable arrays, with : a different major device number to the original non-partitionable md : arrays. The device number is listed as mdp in /proc/devices. ...and the mdadm manpage says: : -a, --auto{=no,yes,md,mdp,part,p}{NN} : : Instruct mdadm to create the device file if needed, possibly : allocating an unused minor number. "md" causes a non-partitionable : array to be used. "mdp", "part" or "p" causes a partitionable : array (2.6 and later) to be used. "yes" requires : : [...] : : For partitionable arrays, mdadm will create the device file for the : whole array and for the first 4 partitions. A different number of : partitions can be specified at the end of this option (e.g. : --auto=p7). If the device name ends with a digit, the partition names : add a 'p', and a number, e.g. "/dev/home1p3". If there is no : trailing digit, then the partition names just have a number added, e.g. : "/dev/scratch3". I just tried this under Qemu (running Ubuntu), and it worked: mdadm --create /dev/mdp0 --auto=mdp --level=5 --raid-devices=3 /dev/hdb1 /dev/hdc1 /dev/hdd1 It creates four partition devices, /dev/mdp0p1, /dev/mdp0p2, /dev/mdp0p3 and /dev/mdp0p4. Might not necessarily work from the Debian installer though. Perhaps you'll have to go into a shell window and do the above by hand...
