That's the part that everyone jumps right over.  How do you change the volume
name on the second volume when both volumes have the same name?  I have not
found a way to specify "rename the volume on sdb2" or anything similar to that.

This issue is now moot for the moment.  I decided that the path of least-likely
screw-up would be to simply disconnect the "main" hard drive in this computer
and attempt to boot off of the drive that I took out of the other one.  This
actually worked and, after running fsck for a couple of hours, everything
seemed to work well enough to copy the data over to the new computer that I got
to replace the one that the hard drive came out of.

Now that the job has been completed, I re-connected the "main" hard drive in
this machine again and I'm now back to the same setup that I had when I wrote
the original inquiry:

[root at mutt ~]# pvscan
PV /dev/sdb2   VG VolGroup00   lvm2 [279.25 GB / 32.00 MB free]
PV /dev/sda2   VG VolGroup00   lvm2 [465.56 GB / 32.00 MB free]
Total: 2 [744.81 GB] / in use: 2 [744.81 GB] / in no VG: 0 [0   ]

At this point, since the second hard drive seems to be in good condition, I
think I would like to re-format it and either add it to the existing volume on
sda2 to make one big logical drive, or just reformat it and make a second lvm
on it again and add it my directory tree.  Which approach would be better?  And
how do I extend a lvm to cover both drives if that's what I end up doing?
