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?)?
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
Thanks, I tried googling around a bit, but didn’t find anything until I looked for Hba-passthrought as suggested by antother comment.
I would like to avoid adding in a pci-card for now as I have enough SATA ports on my mobo and idle-power consumption is one of my main switching reasons, so I’ll see if that works: https://forum.proxmox.com/threads/sata-disk-passthrough-with-smart-functionality.65779/post-296310
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).
