Hi @ all,
über Ostern ging mein NAS Storage mit Raid 6 (8 Disks) kaputt. 2 Defekte Festplatten wurden gemeldet. Daraufhin hab ich es remote ausgeschaltet und 2 Festplatten bestellt. Als ich es jetzt recovern wollte lief zwar ein recover an aber leider nicht die wichtige Datenpartition sondern md8, md13, md9 und nicht md0.
Ich hab schon recht viel versucht, komme aber nicht weiter. Kann mir jemand helfen, ich hab zwar von einigen Daten Backups aber nicht von allem und ich würde gerne alles versuchen bevor ich die Flinte ins Korn werfe.
2 Neue Platten liegen hier (hatte sie jetzt erstmal wieder ausgebaut und geschaut ob ich mit den alten Disks noch was retten kann, aber bisher leider nein).
Kann man hier mit mdadm und missing parameter arbeiter oder ähnliches?
# BIN FÜR EURE HILFE AUF JEDEN FALL SCHON MAL SEHR DANKBAR
Hier ein paar CLI Outputs:
cat /etc/mdadm.conf
ARRAY /dev/md0 devices=/dev/sda3,/dev/sdb3,/dev/sdc3,/dev/sdd3,/dev/sde3,/dev/sdf3,/dev/sdg3,/dev/sdh3
mdadm assemble geht leider nicht ... auch --force hilft nichts (sind ihm zu wenig platten, da er von sdb und sdd die superblocks nicht lesen kann)
mdadm -S /dev/md0
mdadm: stopped /dev/md0
umount /dev/md0
umount: /dev/md0: not mounted
