I was told by my distributions Wiki page that Grub doesn't support RAID 5 or RAID 6 so I would need to create a volume with three disks and set the level to RAID 1: # mdadm --create /dev/md1 --level=1 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1 --spare-devices=1 /dev/sdd1 Is this possible to mirror three identical drive partitions? I was talking to some co-workers and was told that I could only pair two drives on RAID 1. Can anyone please help me understand this? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
