Thanks again for all of your help Sean! I thought I'd ask the rest of the folks here if there was a way for the MD driver to notify my process that something bad occurred or of a status change? So instead of me polling for status from the driver directly(using ioctls) or the mdadm(using ioctls & mdstat), can I register with the driver or and OS interrupt to catch something when changes occur?

You have the following basic options: 1) /proc/mdstat 2) mdadm (from Neil Brown - should be many references to it on the mailing list archives) 3) ioctl (if you want to query from a C program) The ioctl interface is missing the ability to query raid rebuild status. If that is something which interests you, let me know as I created a small patch to add a new ioctl to query raid rebuild information.
