Well, I ended up rebooting the Mini without it's external HDD turned on. The Finder app on my MacBooks were then able to see the other shares on the Mini. When I turned on the external FW drive on the Mini, I immediately lost connection via Finder to browse any shares. On a hunch, I left the external HDD on and attached, but unmounted it. I then ran Disk Utility and ran through both Verify Disk and Repair Disk. I noticed a line that I had never seen before on an external drive validation:

Updating boot support partitions for the volume as required.

Odd... so I mounted the volume off the external HDD again to the Mini. Bingo, the external drive is now available to all of my systems again.

My guess is that running the upgrade with the external disk attached caused some sort of errors due to it's content:
Several bootable Windows and Linux Virtual Box images, and the Time Machine backupdb and sparsebundle images of many systems. I'm thinking that in the future, I'll probably unmount my Time Machine volume before doing OS updates. Funny thing is, at work I always umount any NFS or CIFS shares and the like before doing backups and OS updates. Not sure why it never occurred to me to do this at home. I'll post again if it bugs out. So far, my MacBooks are all backing up the external HDD, so I'm hoping the issue is put to rest.

Thanks for the suggestion 6string. I downloaded the combo update .dmg to be safe and have it hanging out in case I need to run it.
