Adding new disk to LVM + crypt

Hi.

I have currently disk setup like this:

sda1:boot

sda2:lvm-swap

sda2:lvm-root

sda2 was encrypted prior to lvm.

I need to increase lvm-root size with new disk, but I'm unsure how to do that properly. Suppose my new disk is sdb, I guess it's just something like

fdisk sdb, add new partition of type 8e

mkfs.ext3 sdb1

pvcreate sdb1

vgextend lvmgroup sdb1

lvextend -L 100%FREE lvm-root

Is this correct? And what about encryption, do I just encrypt sdb1 before doing the above, like I did with sda?

I'm just looking forward to do this without any dataloss from lvm-root.
