Just a post to try to figure out if what I am doing is correct, or if I am trying to force something that is weird. I have 3 nodes that are identical, each with 500Gb hard disks, which I will later switch to SSD. I would like to install Proxmox and local things on a 100Gb section of the disk and use 400Gb for Ceph storage. When I did the installation, I chose EXT4, and put 100Gb into the box for local. Now, I am trying to set up Ceph, where do I go to select the other 400Gb of space that is unclaimed on the disk?
