At the time I created the RAID array I thought it had superblocks, however if I use mdadm I get these results: # mdadm --query /dev/md0 /dev/md0: 230.08GiB raid5 4 devices, 0 spares. Use mdadm --detail for more detail. /dev/md0: No md super block found, not an md component. If the array really shouldn't have a superblock, is it possible to add one (maybe marking a device faulty and readding it and repeating this for each device)?
