This is what is supposed to happen; when the hardware winds are blowing in the right direction and the software recognizes everything, it even really does happen.
Chris,
I suspect that what happened is that the array was in the process of re-syncing when I powered off the box because it had frozen because of an ATA timeout error.
When I re-booted, the RAID1 root partition was dirty and wouldn't re-sync while the RAID 5 array was re-syncing.
Whatever, I got it back up and running by disconnecting the failed drive.
Cheers,
