Setup description
I am running nextcloudpi on a Raspberry Pi 3.
I configured it to use external storage, which is two merged (via mergerfs) SSDs.
My system broke down after a power outage yesterday and I set it up anew, with the specs below.
Now I tried to upload photos from my mobile phone to the external storage using the nextcloud client (auto upload option). In the previous setup, this went flawlessly for several months. Now my raspberry pi did not report increased storage usage on the external storage, but instead recently reported too high storage usage (28GiB) on the local SD card, which is hosting the OS and nextcloud.
Closer inspection yielded that all uploads seem to be stuck in /var/www/nextcloud/data/ncp/uploads (24GiB).
How could this happen? Is it safe to preliminarly delete the contents of this folder?
NextCloudPi version v1.35.0
Nextcloud version (eg, 20.0.5): 20.0.8.1
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 10 (buster)
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.38 (Debian)
PHP version (eg, 7.4): PHP 7.3.27-1~deb10u1 (cli) (built: Feb 13 2021 16:31:40) ( NTS )
The issue you are facing:
Gigantic amounts of data stuck in /var/www/nextcloud/data/ncp/uploads, even after reboots
