There's a 32 bit overflow in the growfs code (and transaction code
on 32 bit systems) so you can't grow by more than 2TB at a time.
I've got a fix under test for this at the moment.
Can you see if you can grow using:
# xfs_growfs -D <current size + (2TB / FSB) - 1> </path/to/mntpt>
FSB = filesystem block size, and the current size is also in FSB.
You can get both the current size and the FSB from xfs_growfs -n <mtpt>
Cheers,
Dave.
