I changed this with rev 1.55, among other things. The source to the raidctl util is available, so once I'm done fixing the management interface (there is a lot more work to go on this, btw), I'll fix raidutil and make it into a new port. > > I've done a bunch of dd to and from disk with success, > and the postgres' seem to be ok. > > > The performance is nothing to write home about, about > 22MB/s on write (to filesystem from /dev/zero), and > only about 10MB/s on read (from /dev/da0 to /dev/null). > I don't know how to tell if i'm getting errors or anything > with this driver.

The generated assembly for the changed functions is nearly the same as before. The big benefit is that the driver should have a better chance of working on non x86 systems, possibly even amd64. Thanks again for testing this. Scott
