Saya memiliki pengaturan server owncloud pada raspberry pi dengan debian. Sebagai penyimpanan massal saya menggunakan a Intenso drive USB 500 GB yang dicolokkan ke dalam a LogiLink hub USB karena pi Raspberry tidak dapat menyalakan drive USB itu sendiri. Ketika saya mem-boot Raspi semuanya bekerja dengan baik dan itu akan mulai menyinkronkan file saya, tetapi setelah sekitar. 1 jam saya mendapatkan kesalahan berikut:
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
Ketika saya mencoba mengakses drive melalui ssh saya dapatkan
pi@raspberrypi ~ $ ls /media/usb1
ls: reading directory /media/usb1: Input/output error
Dan tidak masalah apakah saya mencobanya sebagai root atau tidak.
Saya melihat ke syslog saya dan menemukan, bahwa itu dipasang dan dilepas drive beberapa kali sebelumnya

Adakah yang tahu apa yang bisa menyebabkan kesalahan ini? Tersangka saya adalah hub USB dan manajemen daya, tetapi saya tidak tahu bagaimana memeriksanya. Mungkin hard drive rusak? Sudah terpasang sesuai dengan / etc / fstab

Terima kasih atas bantuan Anda sebelumnya!
hdparm
karena mungkin disk Anda sedang berputar ...hdparm -S 0
harus menonaktifkan spindown ...
