raid-5 de hardware mdadm quebrado após dist-upgrade

Question

Temos intel-raid-5 na placa-mãe, que também foi montada no Ubuntu e montada como home in fstab . Eu li mais tarde em algum lugar que eu não deveria usar o ataque de hardware no Ubuntu. No entanto, estava funcionando. Mas, após dist-upgrade, ele é quebrado.

Quando usamos um servidor live usb , ele pede duas ativações raid, uma para o mdadm e outra para o RAID Serial ATA. O posterior é novo para mim. E então podemos desmontar e mount -a (que usa fstab).

Mas não pode torná-lo permanente. Quando reinicializar no sistema principal , comentando a entrada fstab para /home , não consigo montar o RAID. O mdadm examina os trabalhos, mas o detalhe e a montagem falham:

$ sudo mdadm --examine /dev/sd[b-d]
