Sounds like your raid-1 went into degraded mode on 1/28 and then it
booted off the old drive.

Maybe.  Try booting with only one drive.  If it doesn't help, boot
with the other one.

I'm really not a fan of dmraid.  My workstation at work was configured
for a dmraid raid-1, and it worked ok until 1 drive failed.  The
machine kept running and the data was safe, but apparently there was
no way to replace the drive and rebuild the array.  If you're going to
raid, I recommend either using a hardware raid controller, or using
software raid in the Linux kernel.  Taking the "fake raid" approach
(at least on Linux) usually seems to turn out to be much more trouble
than it's worth.
