Something else odd has = started happening though, will make a new email for it - usb keyboard no = longer functioning at the beastie menu, but functions when boot = completes. >=20 >=20 The size related problem is entirely about luck - to read the pool, we = get pool config from label, and then read MOS (meta object set), and if = we can not read MOS, we are busted. if we can read MOS, the zfs probe in = boot loader is happy (actual file reads is still different story). = However, whenever the pool is changed, the MOS will get updates and its = location can (and will) change. rgds, toomas
