Eu tenho o novíssimo Asustor AS7008T NAS com 8 X 8TB HDD, em RAID6. Depois de escrever sobre 20 TB, o volume fica indisponível.
Depois:
mdadm --assemble --force /dev/md1 \
/dev/sdc4 /dev/sdf4 /dev/sde4 /dev/sdh4 \
/dev/hdg4 /dev/sdb4 /dev/sda4 /dev/sdd4
Eu recebo:
root@BigBrain:/ # mdadm --detail /dev/md1

Não consigo montar md1 :
root@BigBrain:/ # mount /dev/md1 /volume1
mount: mounting /dev/md1 on /volume1 failed: Invalid argument
Qualquer recomendação será muito apreciada.
