MAINTENANCE FOR MAC OS X 10.6 UPDATE
To test it (strongly recommended in case of spam blocks, etc), plug in a couple of disposable drives (USB keychain drives, whatever), mirror them, unplug one, leave the other overnight and see if you have a warning in your mailbox in the morning. The 10.6.1 Update is recommended for all users running Mac OS X Snow Leopard and includes general operating system fixes that enhance the stability, compatibility, and security of your Mac, including fixes for: compatibility with some Sierra Wireless 3G modems. Substitute in your email address, save it as something like /etc/periodic/daily/150.check-raid, make it executable, and it should mail you a warning (at 3:15 the next morning) if the raid ever degrades. Here's a short shell script I whipped up to fix this. I've seen the aftermath of a couple of servers that had one drive drop out of a software mirror for some reason (I suspect not coming ready in time after a reboot) everything works fine off the remaining drive until, several months later, something goes wrong with THAT drive - and it switches back to the drive that glitched the first time, and the last few months have vanished. I'll second SvenW's warning about silent failures if anything, it's a little too good at surviving a drive failure.
