A bit late, but...
There was a bug in raidtest that it printed wrong file name. What it
wanted to say was:

	raidtest: Cannot open '/dev/da0' device: Operation not permitted

Which means it cannot open /dev/da0 for reading and writing, because it
is already open for writting. If you only want to test reading
performance try 'raidtest test -r'.
