2. dd if=/dev/urandom of=/keys/xvdn.key bs=1024 count=4
3. cryptsetup --verbose -y luksFormat /dev/xvdm /keys/xvdm.key
4. cryptsetup --verbose -y luksFormat /dev/xvdn /keys/xvdn.key
5. cryptsetup luksOpen /dev/xvdm cryptm --key-file /etc/xvdm.key
6. cryptsetup luksOpen /dev/xvdn cryptn --key-file /etc/xvdn.key
7. pvcreate /dev/mapper/cryptm /dev/mapper/cryptn
