          Yes Yes, you're too quick some times sir. I corrected it.

            So with the above 3 pictures and the Array missing.

            I'd obviously have to rebuild the array, and remap items. Additionally, I'll have to recreate my "backup" USB (which isn't a huge deal)

                We need to find the missing array before we can do anything else. As @romo mentioned we need to scan and see if the array is out there somewhere.

                            Should not be there, right?

                                I added an entry into fstab. It may have a typo...

                                    fstab corrected, entry reversed.

                                         mount raid10
                                    mount: /mnt/raid10 is not a block device

                                      Your could run

                                      mdadm --examine --scan >> /etc/mdadm/mdadm.conf

                                      To recreate the conf and see if it fixes the problem. /dev/md/0 should be a symbolic link to /dev/md0
