Public bug reported:

Binary package hint: parted

Behavior observed in Ubuntu 6.10 with parted 1.7.1-2.1ubuntu3.

RAID volume created on a 3Ware 9650SE card, partitioned, and OS installed.  
RAID volume then resized.
Rebooted after resizing and ran parted to grow a partition into the newly 
available space.
parted output:

GNU Parted 1.7.1
Using /dev/sda

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)?
