I recently purchased a Dell R730. My plan was to run a few VMs, and use the 8 drive bays as a a large RAID array. I have been getting to know Proxmox, which i dont really have any complaints about, over the past few months. I currently have 4 8TB drives set up in a ZFS pool in a TrueNAS core VM. It has become full. Last night I went to expand the pool capacity and I find out that its not possible to just add a drive. So now ive been reading about UnRaid, which has that capability. I think i know the right thing to do, but i wanted to hear other peoples opinions on the matter. Should i start fresh with a bare metal unraid install, or should i run unraid as a VM in Proxmox? Im kind of disappointed that truenas pools cannot be easily expanded as i just spent a few months working kinks out with proxmox and truenas
