外部硬盘驱动器上出现 I/0 错误(owncloud 服务器)

外部硬盘驱动器上出现 I/0 错误(owncloud 服务器)

我在装有 Debian 的树莓派上设置了一个 owncloud 服务器。作为大容量存储,我使用Intenso 500 GB USB 驱动器插入一个LogiLink USB 集线器因为 Raspberry pi 本身无法为 USB 驱动器供电。当我启动 Raspi 时,一切正常,它会开始同步我的文件,但大约 1 小时后,我收到以下错误:

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

当我尝试通过 ssh 访问驱动器时,我得到了

pi@raspberrypi ~ $ ls /media/usb1
ls: reading directory /media/usb1: Input/output error

无论我是否以 root 身份尝试它都没有关系。

我查看了我的系统日志,发现它之前曾多次挂载和卸载过该驱动器

但当时它还能正常工作。大约 1 小时后出现以下错误:

有人知道是什么原因导致此错误吗?我怀疑是 USB 集线器和电源管理,但我不知道如何检查。也许是硬盘有缺陷?它是根据 /etc/fstab 安装的

UUID=915a8f36-5c7d-40e3-a451-a3babb0fa610       /media/usb1     ext4    defaults          0       0

提前感谢您的帮助!
