You're raidtab looks mostly ok, not sure about the chunk-size and
persistent-superblock, you're missing hte nr-spare-disks that I have otherwise
looks the same.

I suspect this is your problem, use mke2fs.  From the mkraid manpage:
     those  arrays.   mkraid  only  works for RAID1, RAID4, and
     RAID5 devices; linear and striped md arrays  do  not  need
     initializing.

Try doing mke2fs -c -m0 /dev/md0 then mounting it.
