Is this a copy and paste from the actual output? If not, posting the actual
output may help.

There's nothing wrong with your raidtab, unless those semi-colons are
actually part of the file and not garbled HTML.
Are the partitions mentioned under the device section of the raidtab in use
when you try to make the raid array? What is their partition type? What
drive did you boot from to issue the mkraid command? What is the current
contents of your /etc/fstab?
What is the contents of /proc/mdstat?
