Hmmm, well it was bootable the last time I tried.

Guessing that's the problem, or that they have the same name? They do
have the same name,
lvm lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
LogVol00 VolGroup00 -wi-ao 230.66G
LogVol01 VolGroup00 -wi-ao 1.94G
and the man page says that is bad.

So... define 'carefully'. How do I make sure I am renaming the thumb
drive, not my hard drive, since they have the same name?
Okay, vgrename gives a hint, I need to figure out the UUID.
sudo lvm lvs -v
Finding all logical volumes
LV VG #Seg Attr LSize Maj Min KMaj KMin Origin
Snap% Move Copy% Log Convert LV UUID
LogVol00 VolGroup00 1 -wi-ao 230.66G -1 -1 253 0
MI5Snb-QA02-67Ny-IK4t-iOg9-DPrT-SHlGEw
LogVol01 VolGroup00 1 -wi-ao 1.94G -1 -1 253 1
7uMx6B-KfGU-m9nk-Vqvw-JMnw-3s0m-LhwwBZ
[tburns@cod ~]$ sudo vgrename 7uMx6B-KfGU-m9nk-Vqvw-JMnw-3s0m-LhwwBZ VolGroup01
Volume group 7uMx6B-KfGU-m9nk-Vqvw-JMnw-3s0m-LhwwBZ not found.
Seems like that should've worked, here's the example from the man page:
"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
So I am stumped. Maybe the thumb drive is goofy.
If I did manage to rename it, would that screw it up next time I boot from it?
