RAID lets you cat disks together in a variety of ways: for redundancy, for extending the sizes, &c. softraid is a new feature just released in 4.2 that supports on of these ways: 'mirroring'. Mirroring writes every piece of data to multiple disks, so that if any of them fail the data is not lost, and the disk can be replaced more or less transparently. You'll need to get a bunch of harddrives of different and the same sizes, and plug them all in. Then follow the instructions here: http://www.openbsd.org/cgi-bin/man.cgi?query=softraid&sektion=4 It would help to read this too: http://www.openbsd.org/cgi-bin/man.cgi?query=bioctl&sektion=8 -Nick
