Help, /usr will not mount!

I just lost /usr. Please someone tell me it can be restored.

The thing is, I am attempting to move my drives to another system. My two SCSI drives
are smaller and older and the new system has no SCSI adapter yet, so I thought it best
to remove the two scsi drives from the volume group before moving the 2 IDEs to the new
box. Here's what I did:

pvmove /dev/sda1

Well, pvmove gave me an error message (I can not remember the exact message) and returned
me to the command prompt, so I assumed nothing was done. Afterward, I ran another,
non-destructive command (i think vgscan or something like that) and the process just froze.
Since I was at the console in single-user mode and could not get back to the shell, I
rebooted. Well, on reboot the system could not mount my /usr or /var/video (not important)
because the superblock could not be found. Both partitions were logical volumes.

It really sucks not having /usr as you can imagine. I've managed to get a basic /usr working
that I copied from a CD onto my / partition (that's not a LVM volume).

Running pvmove again, just gives me the same error as before. Running pvmove --abort freezes
again. When I run ps after the pvmove --abort, I see the process status for pvmove is D<L
but it doesn't appear to be doing anything (it's been "running" for over 6 hours now).

Please tell me I can get /usr (and /var/video) back and how.
