/dev/sda, is that your boot device? that will greatly complicate
things... and, your swap is probably not under LVM, /boot certainly
isn't so there's moer on that drive than just part of VolGroup00
I think I'd opt for plan B... install an identical new drive on another
SCSI unit, boot a standalone live CD, and DD image the whole raw
physical drive /dev/sda, then swap this new drive to SCSI unit 0 and
remove the failed one.
