The other half is placed at the top of the vdev slices in the pool. There were few reports recently that such 'orphan' ZFS uberblocks were messing up boot on recent FreeBSD versions. Considering lack of details on how exactly your boot fails, this may or may not be the issue in your case. do "zdb -l /dev/ada0" (and all other slices on ada0) and check whether it reports anything unexpected. --Artem
