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.

    There have been many posts about people running truenas as a VM in proxmox. There are a few things to consider that I’m not well versed on, so I suggest doing some more in depth research, but it’s definitely possible (I did it myself up until the end of last year).

    One of the easiest ways to get the hard drives into truenas is to connect them to a raid card running in IT mode, which allows the OS to directly control the drives (do not raid them, truenas wants the raw disks), and then pass the raid card to the truenas VM

        Oh my home NAS I started this way and it worked great. I only bought an HBA card because I needed more ports. Your mobo probably exposes your SATA controller as a PCI-E device that can be used via pass through in a VM. In my case I booted Proxmox off of NVME drive and passed my SATA controller to a Debian VM where I just use simple NFS and Samba for sharing and SnapRAID for drive parity (but TrueNas should work just as well).

        I had zero issues with it and when I upgraded to an HBA card I just switched the drives to those ports and switched the PCIE device I was passing through and everything just worked (helps I always mount using partition UUIDs).

    You might want to look into all-in-one zfs, which exports your pool as an NFS share internally and externally. In case you use spinning rust, L2ARC and ZIL are your friends.

    My current setup is TrueNAS Scale in Proxmox, drives connected to HBA. Proxmox has ACS override enabled, HBA is passed to the VM.

    Please, do yourself a favor and get an HBA. Do not get a PCIe SATA card, they are unreliable.

    You may take this video from apalrd’s adventures as a good reference. It is using a container instead of a VM so you can leverage Proxmox mount point to mount file system entities (e.g. ZFS datasets) to the container.

    I am using a similar setup so I don’t have to bother passing through all my HBAs or storage devices. My ZFS pools can live in the root OS, i.e. Proxmox, wtihout much hassle.
