Yes, you shold use the MDP devices... look in /proc/devices to find
the major number.

md: fdisk(pid 2486) used obsolete MD ioctl, upgrade your software to use

my fdisk version is 2.11.
should I use another tool for partitioning?

fdisk, cfdisk, sfdisk all work fine.

who is responsible for making the device special files?

You.  (or devfs).

The second 16 minors for mdp correspond to md1
