Hallo zusammen,
ich habe ein größeres Problem.
in einer TS469U mit Firmware 4.20 als Raid 5 mit Hotspare ist anscheinend eine Platte kaputt gegangen und die QNAP war nicht mehr erreichbar.
Nach aus und einschalten kam die qnap mit der meldung:
Code

"603","Error","2018-11-26","21:52:01","System","","localhost","[RAID5 Disk Volume Host Drive: 2 3 4] Volume is unmounted."Hab ich gemacht, dann:

"607","Error","2018-11-26","22:12:49","System","","localhost","[RAID5 Disk Volume Host Drive: 2 3 4] Examination failed."Dann war die Idee, ein Reboot tut gut ...

nur noch 2,1 TB in Lost+found ...
Was kann man noch tun?
Bzw. wie bekommt man sinnvoll die Daten aus Lost+found wieder zurück?
Ist professionelle Datenrettung eine Option?
Hier noch ein paar Infos:
Die defekte Platte ist noch nicht getauscht ...
