I just rsynced everything on one fs to another of the same type and size. Both underlying disks arw partitioned the same, and of the same model number. What could be causing this discrepancy in availiable space?

Check the reserved block count. This is the count of filesystem blocks reserved for the super-user.
tune2fs -l /dev/mapper/crypt tune2fs -l /dev/mapper/crypt2
or
dumpe2fs -h /dev/mapper/crypt dumpe2fs -h /dev/mapper/crypt2
At a guess, I'd say that crypt has a reserve of 0%, and crypt2 has a reserve of 5%, which is the mke2fs default.
