Adding new disk to LVM + crypt
I have currently disk setup like this:
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
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.
