IIRC you can't convert a single-disk (or striped) pool to raidz. You can only convert it to mirror.

There must be an easy way to do this. Nope. -- Fajar _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
