I'm close. I had a 2.7TiB RAID5 array using genkernal, comprising three 1.5TB disks, using the commands mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1 mdadm --detail --scan >> /etc/mdadm.conf I formatted this array as an xfs filesystem. After reboot, however, /dev/md0 is still there, but I get a 'can't read superblock' error. What am I missing?
