Hallo Liste / Leute,

Ich glaub ich hab Mist gebaut ... Nach einem Stromausfall war mein RAID5 "weg". (6 Disks, kein Spare) Der Versuch, das wieder zusammenzusetzen schlug fehl.

Wie bekomme ich das RAID wieder zum laufen ? Der rebuild Prozess startet nicht ? Muss ich /dev/sdg noch mal entfernen und erneut hinzufügen ) (--remove / -add) Danke für Eure Hilfe.
