The issue you are facing:
I’ve been uploading a lot of photos to my Nextcloud server. Now, suddenly, I can’t upload any more. Neither from web interface or app on android phone. All I get i Bad Request. I know for a fact, that my external storage has plenty of available space.

reading through your error I noticed this:

maybe it really is just a full disk?

Thanks for your reply Sackla
It’s a ‘yes’ and a ‘no’ to your suggestion:
I found out, that /dev/root on my banana pro device was full, and this was causing the problem. The Nextcloud server does not use the sd card as storage, however, but a mounted external hdd, /dev/sda, which has 277G of free space. When I freed up some space on /dev/root everything worked again.
I don’t know why /dev/root is important, when Nextcloud data files aren’t stored there, but if someone has an explanation, I’d love to learn about it.

I’m now going to find out, how to keep /dev/root from clogging up. Could it be log files? Anyone know of packages, I can safely remove - perhaps the gui (as I don’t need it).

Thanks

best guess: something is writing it’s logs into /dev/root. php, apache, mysql,…

Makes sense. Thanks very much :slight_smile:
