[dm-crypt] "not a valid LUKS device" after distro change

Guys,

I have an odd problem. I had two luks partitions...both created upon
install on Fedora 20.

Last week, I switched to Ubuntu 14.04. However, anticipating problems, I
*made sure Ubuntu did nothing with these partitions*. No mounting, nothing.

Now, when I boot into Ubuntu, I can mount one manually and my data is
there. However, the other partition tells me "not a valid LUKS device". So,
thinking it might be a problem with Ubuntu, I downloaded the Fedora 20 live
cd, booted up and tried it there. Shockingly, in Fedora 20, *both*
partitions give the "not a valid LUKS device" error, and neither can be
mounted.

The partition I can mount from Ubuntu is MORE_VG-MORE_LV in the output
below. The partition I can't mount from either distro now is
FINALFRONTIER_VG-HOME_LV.

Here's what things like like from Ubuntu (note, /dev/MORE_VG-MORE_LV is
mounted successfully on /home...this is one of the partitions in question):

I do note that Ubuntu uses 1.6.1, while Fedora 20 uses 1.6.2 (see below
output).

Did the Ubuntu 14.04 install somehow corrupt my FINALFRONTIER_VG-HOME_LV
partition? Could the version differences be causing this? Is all my data
there lost? I do have backups for the *really* important stuff, but there's
about 72 hours of coding in there I'd really like to get back if possible.

Any help is greatly appreciated. I'm pasting similar output from the Fedora
20 live session below for your reference as well.

Thanks,
John
