Is it possible to apply vdo on an existing HCI build or does it need to be rebuilt?

The latest gdeploy version is gdeploy-2.0.2-27

I burned the node image yesterday 4.2.5.1 July 31.  I've been playing with Ovirt install for the past week and burned node iso a few times and this image is the first time I've ever seen vdo options in gdeploy.

How do I make sure I have the most recent version of gdeploy, is node behind?

Also can anyone chime in about vdo, is it recommended for use now?  What is its main benefit, does it offer performance boost or more for saving disk space?

Hi,

 Looks like you are using older version of gdeploy. Can you please specify the gdeploy version?
