You should enable PCIe passthrough for Proxmox, so you can passthrough the SATA controllers (assuming nvme boot) directly to TrueNAS (Scale), also you should make maybe 64gb for the boot system, and consider another vm drive for applications separate from your raid drives.Thanks a lot, this works! Where did you get this manual page? I was looking yesterday and did not find anything haha
On a bigger topic: I want to use Proxmox with a VM TrueNAS and some other services (Sonarr, Radarr, maybe Plex). Has anyone experience with this kind of setup? Anything special to look out for?
