what is the output of the following:

cat /etc/raidtab or equivalent
	- maybe a syntax problem ??

	- note that your devices /dev/sda  cannot be used in /dev/md0
	as you have shown

cat /proc/mounts
	- presumably no /mnt/md0 since you have a superblock problem

cat /proc/mdstat
	- presumably nothing since you have a superblock problem

- to fix the super block problems:
	mdadd  --assemble /dev/md0 /dev/hda1 /dev/hdc1
	(or whatever you're using )

	- what are the error messages on the console or logfiles

	- what is the partition type of each disk referenced in 
	/etc/raidtab

	- mkreiserfs /dev/md0
	- mount -t reiserfs /dev/md0 /mnt/md0
