Oh, you use rsync on filesystems, not on raw disk. For RedHat and Fedora 
recently, you would do something like:

    mount /media/dev/sdb1   # the spare disk with the partition in place
    rsync -avH --delete --exclude sdb1 / /dev/sdb1/

By their device names: those are usually in /media automatically with 
recent distributions. Admittedly, I haven't had a chance to play with 
this with LVM partitions, but am looking into it now. It works just fine 
with primary and extended partitions, however.
