Bug 17776

I've been having trouble with my filesystems becoming corrupt and wanted to
verify if it was vinum RAID5 or R4.0.

Four disks in RAID5 configuration (VINUM config included)
vinum start
vinum init myraid.p0
newfs -v /dev/vinum/myraid
mount /dev/vinum/myraid /release
cd /release
restore -rf /dev/rsa0
