Sorry, forgot the list ... ---------- Forwarded message ---------- From: Anselm Strauss <amsibamsi@gmail.com> Date: Fri, Jan 8, 2010 at 4:50 PM Subject: Re: Booting from ZFS raidz To: Sergiy Suprun <sergiy.suprun@gmail.com> I've done some experiments with the 8.0 stable branch and the head branch from SVN. I just recompiled /boot/loader but didn't have any luck. The version from the stable branch gives me the exact same error, the head version fails with a new error. Doesn't seem this is really ready at the moment. I think I'll go with a separate mirror pool for now.
