Yes, I'm doing this as root ..=20 I did the following: $> gpart backup ada0 | gpart restore -F ada1 $> gpart backup ada0s1 | gpart restore -F ada1s1 $> zpool attach bootpool ada0s1a ada1s1a $> zpool attach zroot ada0s1d ada1s1d $> gpart bootcode -b /boot/mbr ada1 $> sysctl kern.geom.debugflags=3D0x10 $> dd if=3D/boot/zfsboot of=3D/dev/ada1s1 count=3D1 $> dd if=3D/boot/zfsboot of=3D/dev/ada1s1a iseek=3D1 oseek=3D1024 (last two steps failed) I'm wondering if this is because ZFS is involved ..?
