Using RAID-5 under vinum was always a somewhat tricky business
for me, but in many cases I could get it to work reasonably well most
of the time. But if I enabled softupdates on that filesystem, I was
toast. Softupdates enabled on filesystems that were not on top of
vinum RAID-5 logical devices seemed to be fine.
So, the interaction that I personally witnessed was specifically
between vinum RAID-5 and softupdates.
