For years, TrueNAS and Proxmox have been seen as two different tools for two different jobs. TrueNAS is the operating system you install when storage is the priority, with ZFS underneath and a feature set built for keeping data intact across drive failures, bitrot, and everything else that can go wrong with spinning drives. Proxmox, on the other hand, is the hypervisor of choice for running virtual machines and LXC containers, backed by a clustering and high availability story that’s quietly been the backbone of countless homelabs. It’s not uncommon to run TrueNAS inside of a Proxmox VM, so long as you do your drive passthroughs correctly.
