Не удается подключить диск под сервером Ubuntu 18.04

Я обновил свой домашний сервер с Ubuntu 12.04 до 18.04. Система содержит 2 диска по 2,0 ТБ в Raid 1. Когда я пытаюсь смонтировать их на 18.04, я получаю следующую ошибку.

mount -t ntfs / dev / md126 / mnt / media

У меня также безуспешно пытается смонтировать -t ntfs-3g.

NTFS signature is missing.
Failed to mount '/dev/md126': Invalid argument
The device '/dev/md126' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Выход из fdisk -l /dev/md126 является

Partition 1 does not start on physical sector boundary.

И вывод gdisk -l будет

И наконец, когда я проверяю mdadm --detail /dev/m126, я получаю следующий результат

Когда я переключаюсь обратно на 12.04 (я установил 18.04 на новый диск) все работает нормально.

У кого-нибудь есть идеи, что происходит не так?

Когда я пытаюсь смонтировать раздел, у меня возникает похожая ошибка mount /dev/md126p1 -t ntfs-3g /mnt/media

Failed to read last sector (3907023047): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
