Installing Proxmox on RAIDZ1 with Shared TrueNAS VM Datasets

I was wondering if this is a do-able thing on proxmox. My motherboard has 3 NVME slots. I was thinking of setting up proxmox on 3x2TB NVME drives in RAIDZ1 ZFS.

If run a TrueNAS VM, passthrough the 3 NVME drives to TrueNAS, would I be able to detect that ZFS pool and create datasets on it?

Therefore I can have proxmox storage, as well as datasets for other Shares for VM/LXC's to connect to for shared fast storage.

Currently I have one NVME for proxmox install and 2x2TB NVM on Truenas as a Mirror. Would like to combine these functions so I have redundancy for Proxmox as well as the Truenas Storage Pool.

Just wondering if this is possible, or if it's just a dumb idea.. Just trying to see if i can get the best of both worlds.

Thanks!

You can't share a disk between two OSs. If you do that you will corrupt the data on it unless you use some cluster-aware filesystem (which ZFS isn't). So don't try to mount a disk on the PVE host that you already passthroughed into a VM.

Thanks, fairly new to proxmox, was just wondring if this was possible. Guess ill just stick to my proxmox backup server and backing up host configs and hope I get many years out of my current setup.
