Oh!  Thanks Steve:

[root at host ~]# parted /dev/sdb p
Error: The backup GPT table is not at the end of the disk, as it should 
be.  This might mean that
another operating system believes the disk is smaller.  Fix, by moving 
the backup to the end (and
removing the old backup)?
Fix/Cancel? Fix
Warning: Not all of the space available to /dev/sdb appears to be used, 
you can fix the GPT to use
all of the space (an extra 1952448512 blocks) or continue with the 
current setting?
Fix/Ignore? Fix
