I'm having a problem getting RAID 1 configured and working with a new RedHat
6.0 install, kernel 2.2.5-15.  I have created all of my partitions on
/dev/sda then
installed the OS on /dev/sda[n].  Then I created the same partitions on
/dev/sdb using
fdisk.  Next I configured /etc/raidtab to include
##########
        raiddev /dev/md0
            raid-level 1
            nr-raid-disks 2
            nr-spare-disks 0
            chunk-size 4
            persistent-superblock 1
            device /dev/sda5
            raid-disk 0
            device /dev/sdb5
            raid-disk 1
##########

note: /dev/sda5 is just a big filesystem (6.0GB) to be used for www pages
and db's

When I do a
$ mkraid /dev/md0 I get:
    /dev/sda5 is mounted
    mkraid: aborted
Then
$ umount /dev/sda5
$ mkraid /dev/md0 I get:
    /dev/sda5 appears to contain an ext2 filesystem -- use -f to override
    mkraid: aborted

I went ahead and did a --really-force on /dev/md0 and cat /proc/mdstat
showed a mirror being made for /dev/md0.  I did a shutdown -r and then on
boot the 'Auto Detecting raid...' showed nothing?  After the boot finished a
cat /proc/mdstat showed nothing about my /dev/md0?  In the Software-RAID
HOWTO Autodetection section the 3rd rule states the partition types must be
set to 0xfd 'fd' by using fdisk, I don't see a type 'fd' when I go into
fdisk?

I've read the Software-RAID HOWTO over and over again, but I am still lost?
Did I start this process all wrong or could it be something simple?

Thanks for any help.
