Hi,

I got the following error when I typed this command:
cryptsetup -y -c aes-xts-plain -s 512 create swap /dev/sda2
Cannot use device /dev/sda2 which is in use (already mapped or mounted).

There is nothing similar in either fstab or mount's output.
There is nothing in /dev/mapper except control.

What else should be checked?

Thanks
