20% of used disk space



I’m trying to achieve having 100% of free disk space for /app in the instance from my app, but I’m unable to find what’s occupying this remaining 20%.

I removed literally everything and command df still shows a disk usage of 20%. Any tips?


Hi @kinduff,

we use btrfs with compression enabled for project storage, so that we can squeeze out the most from the 128MB we provide. The remaining 20% that you get is probably used by the filesystem itself for metadata and other management stuff.

BTW, I was able to obtain 15% instead of 20% by doing this (not really relevant to be honest :smiley: )

rm -rf /app/* /app/.*
sync -f /app
