TrueCrypt está destoying volume mdadm

Estou configurando um novo servidor de arquivos usando a mesma configuração de armazenamento do meu servidor existente, mas o procedimento está falhando e não consigo entender o motivo. Meu objetivo é criar um volume TrueCrypt em cima de um volume RAID 10. no entanto, quando eu inicio truecrypt -c , ele destrói o volume RAID. O mesmo procedimento funcionou para o meu servidor anterior, então não tenho certeza do que está acontecendo.

Meu procedimento:

# create a data partition on each disk (/dev/sdb, /dev/sdc, /dev/sdd, /dev/sde):
fdisk /dev/sdX
new, p, 1, 4096, 2930273071, type, da, write

# combine data partitions into raid10 array:
mdadm --create /dev/md0 -v --raid-devices=4 --chunk=512 --level=raid10 --layout=f2 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

# create a truecrypt volume on the new data partition /dev/md0:
truecrypt -c /dev/md0

logo após o início do truecrypt, recebo uma falha de componente do mdadm para um ou mais discos:

$ cat /proc/mdstat; echo; mdadm --misc --detail /dev/md0

Esta não é uma falha real do disco porque a) o smartd não vê nenhum problema com os discos eb) eu posso criar um volume TrueCrypt completo em cada um dos discos individualmente.

Eu também tentei criar uma partição em / dev / md0 (ambos os dados 83 / Linux e da / Non-FS) e então criar um volume TrueCrypt na partição / dev / md0p1 (de onde veio essa saída do dmesg), mas isso também não funciona.

Estou assumindo que o TrueCrypt está de alguma forma destruindo metadados importantes do mdadm. Mas o que é estranho é que esse procedimento exato funcionou bem antes. O que está acontecendo aqui?

EDIT: quando este procedimento funcionou, provavelmente foi usando TrueCrypt 6 - eu vou tentar com 6 para ver o que acontece. Eu vou atualizar com os resultados ...

Essas mensagens de erro realmente são lidas como erros de disco, não como corrupção de metadados. Eles estão vindo da libata, não mdraid.

Eles podem não ser problemas com o disco atual. Por exemplo, pode haver um erro de driver SATA, um controlador SATA defeituoso, um conector defeituoso, um cabo defeituoso, etc.

Você pode vê-lo somente ao criar sobre o array mdraid devido a diferentes padrões de E / S. Mas tenho certeza de que, mesmo que você consiga alguma outra coisa para funcionar, não será estável, porque na verdade você tem drivers ou hardware escamosos.

BTW: o que diz smartctl -x ou smartctl -a ? Tem um contador de erros SATA?
