edited October 2019 in Personal Cloud Storage
I had a power failure and had te reset my NSA325 in order to get it back on the network. I had entware setup previously.

Now there seems something wrong. 
When I check for firmware update the popup  says: Connection to the server hung.
There are no packages on the packages tab and the buttons are greyed out. The message bar at the bottom says: 
This feature is not available for there is no volume.

The volume section mentions my two disks (jbod), 70% used, message bar at the bottom says: Ready.

In the log section I see 13 comments. The last one, from today reads:
Volume is FULL. It is recommended to reserve freespace for operating system to work properly.

I would like to get my system back to where is was:
- running entware
- sharing my files on the network through nfs
- etc.

I think there is something wrong, but don't know where to start.

Regards, Bobby

    Start with the Telnet Backdoor. If you have managed to get access over telnet, post the output of
    ls -l /i-data/<br>ls -l /etc/zyxel/storage/<br>cat /proc/mounts

    /etc/zyxel/storage/sysvol is supposed to be a symlink to the volume. In your case it's a directory. /etc/zyxel/ is the mountpoint of a flash partition, so I think your error
    Volume is FULL. It is recommended to reserve freespace for operating system to work properly.
    is caused because that directory is now treated as volume, and the flash partition is tiny.

    Solution:
    <div>rm -rf /etc/zyxel/storage/sysvol</div><div>ln -s /i-data/58e75e09 /etc/zyxel/storage/sysvol</div><div>reboot</div>

    rm -rf /etc/zyxel/storage/sysvol
    took a while to complete, but no error.
    
    ln -s /i-data/58e75e09 /etc/zyxel/storage/sysvol
    reboot
    
    After reboot the device is not on the network anymore. It hasn't receiver an IP from my gateway. Tried manual reboot with the button on the device, but same result.
    
    Should I reset it, or would I then be back where I was?

    Don't know. How did you reset it last time? Keeping the button pressed until the 3th beep? If not, it was no full reset. AFAIK a full reset puts a new filesystem on the flash, and then I wouldn't expect a timestamp in 2015 on the sysvol symlink.

    Anyway, when the device doesn't show up in network you don't have much choice, do you? Unless you have a suitable serial cable.

    Well a couple of extra resets (one beep) worked!

    Thanks!
