Creating MD Devices with Red Hat 5
By default, Red Hat 5 has only one MD device file (/dev/md0) and it is
available in the /dev/ directory. With this file only one MD device can be
started at any time. To use multiple MD devices you need to create
multiple MD device files in the /dev/ directory. To create an MD device
file, use the following command:
# MAKEDEV -x /dev/md*
Where * is the MD device number you need to create.
For example, to use an MD device such as md1, you need to create the
following file /dev/md1 using the command # MAKEDEV -x /dev/md1.
