The array is still not being recognised at boot, with the same 'cannot read superblock' error. I also tried re-running mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1 I get the error mdadm: device /dev/sdb1 not suitable for any style of array. What is going on here?
