Hi, I am fairly new to linux but I'm building one of the backblaze storage pods:

blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build-cheap-cloud-storage/

I have followed the specs they give exactly and i have almost completed it but I am stuck trying to mount the raids. There are 3 RAID6 and i recieve the same error for each one
Code:
mount /dev/md0 /mnt/raid0
mount: wrong fs type, bad option, bad superblock on /dev/md0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
This is what i have done(ill just show one since they are identical except for which drives make the raid of course)
Code:
    mdadm --detail /dev/md0
    /dev/md0:
