I’m currently planning to build a new server after I discovered what my system uses in Idle. As I have to set up a new system anyways I would like to add a NAS to it to manige my storage. Currently I just have a zfs-Pool in proxmox for my Data-Drives and all VMs/Containers that need access have escalated rights and can directly access the pool (and all other storage on proxmox) which is a bit janky and definetly not best practice security-wise. Another negative side effect is that the drives are barely spun down. Thats why I now want to have a Nas as the only System controling the Drive pool. Here’s where my question comes up: Should I run TrueNas (scale?) in a VM and pass the drives through somehow (is that possible without mounting them in Proxmox, as I would like them fully controled by the Nas, including running the zfs pool, etc. ?)? Or do I install TrueNas scale and then run Proxmox as a VM inside, would my performance penalty be huge here, would I still be able to pass throught USB/PCI devices (maybe even the cpu’s igup to forward that to jellyfin if that’s even possible in Proxmox?)?
The best way to do this is to run a truenas VM within proxmox and passthrough your HBA into the truenas VM. That will give truenas full control over any drive connected to that HBA. The performance overhead isn’t that much so don’t worry about it.
In a pinch passing through drives also works with ZFS, but obviously you lose SMART etc. I ran that for a few weeks before I managed to get ACS override working and my ZFS pool got picked up when TrueNAS started.
ZFS not have access to smart only works up until a drive starts acting up. Without SMART ZFS can’t accurately determine if a drive is failing and lock the pool in order to prevent further data loss.
I’m aware, but I’m saying in a pinch it will work and when you pass your HBA fully you won’t need to reconfigure anything, at least I didn’t
