So now df agrees with the webif regarding free space but AFAIK reserved space shouldn't affect humax operations since it runs as root.
Also I am not sure why reserved was 20%+
edit: Obviously didn't reset reserved after experimenting https://hummy.tv/forum/threads/undelete-package-deletes-files-too-early.10653/post-163209
