This is huge thing (called "Slop Space") that I noticed after I bought all ZFS NAS parts! It wastes much capacity by default if drive count is not ideal. IIRC

It wastes much capacity by default if drive count is not ideal. IIRC use larger recordsize (1MB or above) and enable compression almost solves issue. I use default 128K recordsize for small files zvol for performance, and use larger recordsize for the rest of zvols.
