Chapter 22 Switch back crypted swap

Ilonka

Hi all,

I did the excercise in a VM and everything was fine.

Now I try to switch back swap into uncryted status. But when I try $mkswap /dev/dm-1 my system tells me that it can't be opened because the device or ressource are reserved.

But actually there isn't a swap active. 

Can somebody tell me what I'm doing wrong??

Thanks in advance 

Regards

Hi Ilonka,

Did you deactivate the swap device, and used the luksClose operation with the cryptsetup command before trying to format the partition?

Regards,

Luis.
