Восстановить конфигурацию рейда (сервер Ubuntu 8.04)

Потерянный RAID

После перезагрузки AWS я потерял RAID (mdadm), а диски вроде в порядке (по отдельности).

Симптомы

mdadm не работает

После перезапуска машины (остановка и запуск на Amazon AWS) устройство / dev / md0 не работает:

[11:52:17 root :)  ]$ cat /proc/mdstat 
Personalities : 
unused devices: <none>

[12:03:09 root :) ]$ mdadm -A /dev/md0 
mdadm: no devices found for /dev/md0

Диски по-прежнему считаются частью RAID

Но все raid-диски кажутся частью RAID:

[12:05:24 root :) ]$ mdadm -Q /dev/sdk
/dev/sdk: is not an md array
/dev/sdk: device 7 in 8 device undetected raid0 /dev/md0.  
          Use mdadm --examine for more detail.

И:

[11:51:40 root :) ]$ mdadm -mdadm --create /dev/md0 --level=0 --raid-devices=8 
              --chunk=1024 /dev/sd[defghijk]
mdadm: /dev/sdd appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sde appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdf appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdg appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdh appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdi appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdj appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
mdadm: /dev/sdk appears to be part of a raid array:
    level=raid0 devices=8 ctime=Wed Oct 27 10:38:53 2010
