First, look out for snapshots, an old one can eat a lot of space.
Second, just enable compression for the rpool (lz4), that will
affect newly written stuff and helps to just lift you over the
fence. It's also even a bit faster as less has to be drawn from the
platter, and CPUs are fast enough nowadays to easily cope with the
compression overhead.
