Hi,
I would like to share how I fixed USB 0size issue on my device (MyCloud Gen1).
First of all I want mention that my device has v04.05.00-342 firmware. I was using USB backup (SafePoints) function for many years. Couple of days ago I was playing with the Share where SafePoint is saving backups and switched off public access and Media Serving. I noticed the message saying the Share is not availabe and when I checked USB it displayed 0Kb size.
First, I thought I had to unplug USB drive and plug it back. The size was still 0Kb after.
I tried to reboot the device - no luck.
In fact, I spent a week digging into various bits and pieced and found some interesting thing.
When USB is plugged into the device, it mounts this storage twice (i noticed it by looking into /etc/mtab via SSH connection).
The following bits are purely about the issues observed via SSH connection to the derive.
Actually there were 2 entries in /etc/mtab. One entry - mounting usb to /var/media/… folder, other - to /nas/…
The device expects USB storage to be mounted as /var/media only.
I have unmounted /nas/… by running umount /nas/… command and my problem was fixed. I can see the real size of USB drive in the UI as well as keep running my SafePoint backups.
I still don’t understand why USB drive is mounted twice.
I will keep my investigation going.
Hope this post will save time and emotions to others experiencing the same issue.
