What ? really?  Is this something I should worry about? I have a 30gig
partition on boot disk, 40gig disk, and a 45 gigs disk, they seemed to
raid0 together beautifully, but haven't been used much yet. Will they
fall over later on?

Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/raid0e 102053179       27 96950493     0%    /disk01

START disks
/dev/wd0f
/dev/wd1e
/dev/wd2e





While I'm on the subject, thinking of a simple way of doing on disk
encryption (crypt filesystem) and RAID looked to be fairly promising. 
Do all READ and WRITE requests go through one set of functions in it? 

The rf_netbsdkintf.c file looks promising, it has raidread() and
raidwrite() which both call raidstrategy().
