Hello. I have also just resized a RAID volume and too experienced this
problem.
Reading through the debian bugreport ExplodingLemur posted it seems that
it's fixed in latest gparted version.
Here is the output of parted:
[EMAIL PROTECTED]:~# parted /dev/sdb
GNU Parted 1.7.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print
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)?
