TrueNAS on Proxmox, good idea?

[Pete5]

Hi,
my initial idea was to configure my F4-424 Max as a new homeserver as following:
- 2 NVME SSDs used for OS, containers and VMs
- 4 HDDs used by a virtualized NAS OS like OMV or TrueNAS via PASSTHROUGH and configured as RAID5

In general, do you think it is a good idea to virtualize a NAS OS + PASSTHROUGH (HDDs) from a technical point of view concerning reliability, maintenance, configuration, failure case, etc?

Regards Pete

As far I know TrueNAS recommends to use a dedicated SATA PCI HBA for passthrough to the NAS vm so the NAS OS has exklusive access to the storage disks.

That's what I do at my TrueNAS Scale VM

This info I found somewhere as well, but I'm not sure if it's valid for the "old" TrueNAS based on FreeBSD or for the "new" FeeeNAS Scale based on Debian.
However, I couldn't find out if my F4-424 has regular PCI controller or an HBA. I don't know what the difference is, but there seems to be i difference.

The guides & HowTos aren't clear concerning this point, some do just a passthrough of the disks against the above mentioned recommendation.

The recomendation is the same for both.

It worked...
I installed TrueNAS as a VM and passed both SATA controller to TrueNAS successfully, all 4 HDDS are shown in TrueNAS.
