Hi, I noticed today that I couldn’t upload big files even after changing the appropriate environment variable. So when I logged into the admin page, the following notification came up:
The drive that hosts the mastercontainer volume has less than 5 GB free space. Container updates and backups might not succeed due to that!
I’ve searched this error message and can’t find how to deal with this.
My data is stored in an Unraid server and there’s still plenty of space left. I did see a loop2 drive pointing at / that is almost full, and since the file I’m trying to upload is 11 GB, it makes sense that there isn’t enough space to handle files.
What is stored inside this loop2 drive and how do I purge its files?
