Looking for help with RAW/Local Storage


I have a 4 node Elasticsearch Cluster, each node running on a separate hypervisor. For the current setup, I have NFS as the system & image DS. It is not performing well, so I wanted to use some space on the hypervisor’s disk (/dev/mapper/volgrp03-localhdd). I am unclear how I need to set up the DS/Image/Template to achieve this goal. Ultimately I want a new disk in my template ~200GB that maps to local storage on the dev listed above. I have setup a rdm DS and a datablock image, but because it is persistent, I can’t reuse that same image on vm2. I feel like I am close, but just missing some key element.
