I was running Slackware 10.1 and I was required to switch over to
Fedora Core 4. I backed up my /etc/lvm folder because I knew I'd run
into problems. Well, I ran into problems as expected....
Just about any LVM related command will give me the error:
"Couldn't find device with uuid 'k4Px6F-wwSG-mDY6-tne2-RNVx-G3fI-mWUw4r"
Now, according to my volume group (homevg) backup, it is refering to
my second partition in the strip: /dev/sdb1.
Here is the output from pvdisplay.

OK now that I have that out of the way, here is my backup volume
group file I made just before reinstalling.

FINALLY:
Notice the UUID for PV2. Thats the UUID that LVM is complaining about,
but according to pvdisplay, that UUID doesnt exist.
What do I do!?
