Потерянные диски RAID6 при перемещении в новый ПК (mdadm) (недостающий суперблок)

Заранее спасибо за любую справку Вы смогли давать.

Ранее я пытался переместить свой массив mdadm с Сервера Ubuntu на виртуализированный Сервер Ubuntu, работающий на хосте ESXI.

Я соединил их и видел диски в ESXI, затем используемая передача для получения их к экземпляру Сервера Ubuntu, но это не работало, и я мог только видеть трех из них.

Затем я положил обратно диски в старый сервер и загрузил его, где ему не удалось видеть массив на начальной загрузке, и он все еще перестал работать.

Массив должен быть RAID6 на/dev/sd {a-f}.

У меня есть резервные копии самых важных 2 ТБ, но существует много данных, для которых это - единственная копия (который я могу позволить себе потерять, но надо надеяться не буду иметь к).

Я попробовал:

mdadm - собираются - сканирование - подробный:

mdadm: looking for devices for /dev/md0
mdadm: no RAID superblock on /dev/sdg1
mdadm: no RAID superblock on /dev/sdg
mdadm: /dev/sdf requires wrong number of drives.
mdadm: /dev/sde requires wrong number of drives.
mdadm: no RAID superblock on /dev/sdd2
mdadm: no RAID superblock on /dev/sdd1
mdadm: no RAID superblock on /dev/sdd
mdadm: no RAID superblock on /dev/sdb2
mdadm: no RAID superblock on /dev/sdb1
mdadm: no RAID superblock on /dev/sdb
mdadm: no RAID superblock on /dev/sdc2
mdadm: no RAID superblock on /dev/sdc1
mdadm: no RAID superblock on /dev/sdc
mdadm: /dev/sda requires wrong number of drives.

Который дает это в/cat/mdstat:

Disk /dev/sdf doesn't contain a valid partition table

Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table.
However, it does not have a valid fake msdos partition table, as it should.
Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
partition tables.  Or perhaps you deleted the GPT table, and are now using an
msdos partition table.  Is this a GPT partition table?
