Ensure the array always get mounted on boot

echo '/dev/md0 /mnt/nas ext4 defaults,nofail 0 0' | sudo tee -a /etc/fstab

returns: 

/dev/md0 /mnt/nas ext4 defaults,nofail 0 0

NOTE: This adds an entry into the /etc/fstab file.

The x-gvfs-show option can also be used, which will let you see the RAID in the sidebar of the gnome file manager. 

/dev/md0  /mnt/nas ext4 defaults,x-gvfs-show 0 0
