Can you check the following 1) what does /etc/mdadm.conf say for /dev/md3? it should have a line like: ARRAY /dev/md3 level=raid1 num-devices=2 UUID=1bcb5496:c7d158e6:14c0bbc3:de3ed72e 2) what does "blkid | grep sd[ab]x" say? (x is the partition number) both should have the same UUID number: /dev/sdb3: UUID="1bcb5496-c7d1-58e6-14c0-bbc3de3ed72e" TYPE="linux_raid_member" /dev/sda3: UUID="1bcb5496-c7d1-58e6-14c0-bbc3de3ed72e" TYPE="linux_raid_member" 3) what does /etc/fstab show for your boot (root?) partition? should be: UUID=61a11dc6-b7b7-4fb0-893c-83ce87be9324 / ext4 defaults 1 1 4) what does "blkid | grep md3" show? should be like: /dev/md3: UUID="61a11dc6-b7b7-4fb0-893c-83ce87be9324" TYPE="ext4" notice the UUID's match for items 1 & 2, they also match for 3 & 4 mdadm.conf says build the array out of the partitions with the devices with UUID 1bcb5496:c7d158e6:14c0bbc3:de3ed72e, which in my example are /dev/sda3 and /dev/sdb3 Line 3 says that the / (root) partition is on UUID device 61a11dc6-b7b7-4fb0-893c-83ce87be9324 this UUID is the RAID device UUID, make sure it is not pointing to the UUID of the disk. line 4 shows the UUID for the md3 partition. Hopefully its this simple and not something else going on.
