First, raid0 != linear.
To make a running md0 device do:
1.) recompile your kernel if 'dmesg|grep personality' does not display
your raid level.
2.) create /dev/md0 with /dev/MAKEDEV script or look into
/usr/src/linux/Documentation/devices.txt to find out minor and major
numbers.
3.) do a 'mdcreate linear /dev/md0 <list-of-devices>' (or so, look at
manpage).
4.) do a 'mdadd -a'
5.) make a filesystem on it
6.) mount it.
I may have skipped a step. look at the manpages of md... tofind out what
to do exactly.
