I have some additional questions: 1. I managed to create a new pool, but whenever I tried to import it, the system stopped responding. Did you have similar problems? 2. After the stability problems are solved, do you think it makes sense to run ZFS on a rather low-end board? Is it going to be usable? 3. Is there a way to enable module compilation with the crochet script? Why is it disabled? 4. Is it better to ask such naive questions here (freebsd-arm mailing list) or at the FreeBSD forum <http://forum.freebsd.org>; in the future? Cheers Henryk
