mkswap /mnt/swapfile step is missing i guess. I am able to create swap after only this step.

# swapoff -v /swapfile
# chmod 600 /mnt/swapfile
# swapon /mnt/swapfile
# swapon: /mnt/swapfile: read swap header failed: Invalid argument
# mkswap /mnt/swapfile 
# swapon /mnt/swapfile
# free  -m

Sample Output

              total        used        free      shared  buff/cache   available
Mem:          15883        2337        9955          16        3591       13206
Swap:          2047           0        2047
