That ran without errors.. but sadly did not solve my problem of the UEFI not recognizing it as a bootable disk.     I think the problem is my particular UEFI doesn't recognize GPT drives that don't have an EFI partition on them. 

So I gave up.  My server has been down for too long.   I took half the zfs mirror, created it with a MBR partition and installed FreeBSD 9.2 on it, and my UEFI can boot it in legacy mode.   From there I can mount the other half of the mirror and copy files off.   A painful process but at least I have a way forward.   

Thanks for the suggestions.
