[SOLVED] Proxmox and TrueNAS on HP DL380P G8

[Kanze]

Hello,
I'm struggling to understand the best way to configure disks for TrueNAS VM on my HP server that has one physical array controller .
I have 4 disks in raid 1+0 (created using the HP smart array tool) were is installed Proxmox and all the VMs, I have also another 1+0 raid (also this created using the HP smart array tool) that uses the other 4 disks that I want to dedicate to TrueNAS, but I can't understand how to configure Proxmox to allow TrueNAS VM to see this raid.
Is it possible? Am I missing something?

Thanks in advance!

Bad idea. ZFS shouldn't be run on top of hardware raid controllers. See here: https://openzfs.github.io/openzfs-docs/Performance and Tuning/Hardware.html#hardware-raid-controllers

I personally would buy a HBA card (LSI SAS2008 or SAS2308 are commonly used) exclusively for those 4 disks, then use PCI passthrough to passthrough the whole HBA into your TrueNAS VM so TrueNAS can directly access the real physical disks without any abstraction layer in between.

Got it @Dunuin, thanks to point this out!
