https://bugzilla.redhat.com/show_bug.cgi?id=1386766 was released in 3.10, but the latest docs in 2020 are still referencing this 1GB limitation and say it's not something that can be overridden.

> Considering the fact that trash directory is consuming the glusterfs volume space, trash feature is implemented to function in such a way that it directly deletes/truncates files with size > 1GB even if this option is set to some value greater than 1GB.

Please update the docs.
