The internal controller only has 2 ports, one of which is the system
disk (not in RAID).

I've made 5 file-backed devices with mdconfig (with files on the system
disk) and united them into a RAIDZ to rule out the controller. ZFS seems
to run fine using this configuration (the resulting device is smaller,
of course), e.g. it's still grinding its buildworlds OK.

For testing, I set up the original disks into a GEOM stripe and newfs'd
it into UFS2. This configuration also seems to be working fine, so the
controller and drives are OK also!

Am I stupid or what?

Thanks,
