For a while now I have a old spare Intel Madrona server. It has in
current configuration one SCSI backplane with 5 SCA plugs and four
Seagate Cheetah disks (old model: 4.3GB 10000rpm). The SCSI
controller is onboard Symbios 875. I did some vinum raid-5 tests in
November, all what I got was massive filesystem corruption and
panics after the degraded volume got rebuilt. I'll probably have
this box for yet two weeks or so and my time isn't so limited now,
so.. What I can do to help you besides installing latest -stable? Do
you have some formalized test procedures or anything to prove the
stability of raid-5 configuration?

Thanks
