You don't need GPT for software RAID unless one of your disks is >2TB. For 
example I am running a 3TB XFS file system directly on /dev/md0. Have you done 
a reboot, maybe the new size has not really been applied? Never tried it with 
LUKS/cryptsetup though, maybe it won't to above 2GB.

# df -h /dev/md0
Filesystem            Size  Used Avail Use% Mounted on
/dev/md0              2.8T  1.5T  1.4T  53% /san1
