Hallo,
ich habe ein QNAP TS-439 mit encrypted file system, das plötzlich das RAID5 als "unmounted" zeigt und keine Zugriffe mehr ermöglicht. Es war kein Stromausfall oder unsicherer Shutdown vorher, allerdings am Tag vorher Firmware-Update auf 4.1...
Der QNAP Support kann/darf nichts machen, da es sich um ein encrypted volume handelt... 
Weiß hier jemand Rat, was ich noch tun kann, um das Volume zu mounten und an die Daten heranzukommen?
Vielen vielen Dank!
Beste Grüße
Manfred
