Ich habe einen owncloud Server auf einem Raspberry Pi mit Debian aufgesetzt. Als Massenspeicher verwende ich einenIntenso 500 GB USB-Laufwerkdie an einenLogiLink USB-Hubweil der Raspberry Pi das USB-Laufwerk nicht selbst mit Strom versorgen kann. Wenn ich den Raspi boote, funktioniert alles einwandfrei und er beginnt mit der Synchronisierung meiner Dateien, aber nach ca. 1 Stunde erhalte ich die folgende Fehlermeldung:
Data directory (/media/usb1/owncloud/data) not writable by ownCloud
Permissions can usually be fixed by giving the webserver write access to the ownCloud directory
Wenn ich versuche, über SSH auf das Laufwerk zuzugreifen, erhalte ich
pi@raspberrypi ~ $ ls /media/usb1
ls: reading directory /media/usb1: Input/output error
Und dabei spielt es keine Rolle, ob ich es als Root versuche oder nicht.
Ich schaute in mein Syslog und fand heraus, dass es das Laufwerk mehrmals gemountet und unmountet hat, bevor

Hat jemand eine Idee, was diesen Fehler verursachen könnte? Ich vermute den USB-Hub und das Powermanagement, weiß aber nicht, wie ich das überprüfen soll. Vielleicht ist die Festplatte defekt? Sie ist laut /etc/fstab gemountet
