Hi, I believe I need to create a Storage Block which I was unaware of as I thought one would be able to use part of the free space on the disks automatically provisioned by the node installer, I believe this requires a reinstall and creation of a new volume or reduce the current size of the volume used and create a new volume on the live system. Additionally on another note how do I remove my email address from showing on posts this is not great to have it showing. that file you wanted is below...
