Kan niet meer opstarten, md0 raid 0

[Verwijderd]

hello,

Ik krijg mijn ubuntu server niet meer opgestart, hier gaat het over een server waar ik 4 schijven van 500 GB in heb en die in RAID 0 staan. Die server makt iedere nacht een backup (dat dacht ik toch). Maar nu krijg ik dit te zien bij opstarten server.
hier wat ik al heb geprobeerd :

Dit vind in ook raar !!

code:

root@backup2T:/etc/init.d# cat /proc/mdstat
Personalities : [raid0]
md0 : inactive sda4[0](S) sdd1[3](S) sdc1[2](S)
      1453432384 blocks

unused devices: <none>

Ik kan niet meer op mijn home partitie
Hoe komt het dat mijn sdb niet meer in de array zit?
En wat kan ik doen om deze terug erin te smijten ?

Heb je deze al gezien: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/188392 ?

ja,

al gezien

is toch vervelend

Als je mdadm eens zonder --scan probeerd, maar met de device namen.

[laurencevde]

Allereerst: raid0 over 4 schijven? je bent gek! je hebt een kans van ~20% dat je binnen een jaar een stukke array hebt (uitgaande van een faalkans van 5% op jaarbasis voor behoorlijke schijven). Waarom geen raid5?

mdadm --add /dev/md0 /dev/sdb1 om hem weer toe te voegen. Als je het durft. Als de schijf nog goed werkt, niet corrupt is, en herkend wordt als zijnde bij de array, zou dat moeten werken. Als het niet werkt ben je je data toch kwijt...

Maar voordat je dat gaat doen zou ik eerst de status van de schijf bekijken. smartctl --all /dev/sdb.

enne, hoe ziet je /etc/mdadm.conf eruit?

sidenote: Als je bios ahci ondersteunt, kan je dat beter gebruiken...

[Demo]

Ik zou dan mdadm -re-add proberen, "re-add a device that was recently removed from an array." volgens de manpage. smarttools installeren en je schijven uitlezen met smartctl kan inderdaad ook geen kwaad.
* Demo heeft deze week een RAID5 array afgeschreven
