                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

                                  Using RAID 10 in names anywhere is very confusing and hard to read. I think several of these issues are partially stemming just from poor naming conventions. Name mount points by purpose, not technology.

                                    You can't mount /dev/md0, because according to the mdadm --examine --scan ouput, the array, is at /dev/md/0

                                      Good eye, that was hard to see.

                                        What is the ouput for:
                                        cat /dev/md/md-device-map
