   parted /dev/vdb1 mkpart swap1 linux-swap 2048s 601MB
   mkswap /dev/vdb1
   swapon /dev/vdb1

   #With lsblk -fs get uuid

   #on /etc/fstap
   UUID=”***” swap swap defaults 0 0

3. # cat /proc/partitions –> to know which partition you will use the fdisk on
   # fdisk /dev/???
   p –> n –> p –> default –> default –> +600M –> t –> 82 –> p –> w
   # partx /dev/????
   # partprobe
   # mkswap /dev/????
   # swapon /dev/????
   # swapon -a
   # blkid –> to get the new swap partition ID
   # vim /etc/fstab
