For disk encryption to work you'll need to shrink file system on /data partition without shrinking the partition itself by 32 kilobytes

# 8 blocks by 4 kilobytes to make space for encryption footer

# where reduced_size = current_size - 8

resize2fs /dev/block/mmcblk0p49 reduced_size

i.e.

resize2fs /dev/block/mmcblk0p49 13449073

Resizing the filesystem on /dev/block/mmcblk0p49 to 13449073 (4k) blocks.
The filesystem on /dev/block/mmcblk0p49 is now 13449073 (4k) blocks long.
