LVM-Cache on fresh Ubuntu server install

[Stephen Partington]

I have set myself a project and am building a server. It has a 1T spinning
disk and 128G SSD installed. I wanted to explore the various options for
SSD caching and its a toos up betweeen LVM-Cache and bcache. I am working
on going with LVM-Cache but i am not seeing many options on building such a
configuration from fresh install.

Sadly the Ubuntu server installation does not have the option of setting up
LVM for anything other than its most basic configuration out of the get go.
What I understand about LVM is that you can build your LVM group and then
migrate/expand it without a full install/wipe or 3rd disk device to host
your core os installation. Can this be done for LVM cache as well?
