2) the devices in /dev/ufsid/ are associated with partitions on the adN

ataraid or geom/glabel is responsible for this).
This is a long-standing bug in ataraid. It should not be possible to
open the individual members of a RAID set for writing, and the
existence of the ataraid should spoil other consumers of the
individual disk providers. (The same thing happens with regular UFS
labels. I think the actual problem is that ataraid works behind
GEOM's back, but doesn't withdraw the disk providers so GEOM thinks
they are separate devices.) The only workaround that I have found is
to disable the poor-man's-RAID and use gmirror instead.
In general, having used both ataraid and gmirror systems since 5.x, my
impression is that gmirror works better and is more manageable.
