Hi Craig, > ZFS: i/o error - all block copies unavailable > > I don't fully understand all this logic. Is there a bug that can be fixed here? Yes - a flag needs to be passed to userboot to tell it to ignore ZFS filesystems. This is analogous to the decision to use boot2 (implicit UFS) vs zfsboot (explicit ZFS) as the 2nd-stage loader on a real disk. It didn't look possible to do this without changing the userboot ABI, but, it's probably time to bump that. later, Peter.
