All I did was this..... from: f_eval_catch $funcname gpart "$GPART_ADD_LABEL" \ zfs$index freebsd-zfs $disk || return $FAILURE to: f_eval_catch $funcname gpart "$GPART_ADD_LABEL_WITH_SIZE" \ zfs$index freebsd-zfs 800Gb $disk || return $FAILURE The raidz will boot if I pull the other drives and let it boot with just the 4 zfs raidz drives so I know it will boot. Just have to get it to play nice with the other systems (win7 and 10.0) and boot. I just need to configure out how to make it boot with the other drives. Hand holding required.
