[SOLVED] can we create bunch of lvm-thin pools with individual drives and then attach that to unraid vm?

TLDR: I am a noobie and learning Proxmox

Usecase: Plex media, games storage, other random stuff

I am curious about this pattern. I want to let Unraid manage the pool or array, but I simply want to pass the drives on along as lvm-thin. These LVM-Thin pools seems to only consist of one drive, at least thats how i can select it in the gui.

I assume this method is essentially passing on the virtual drives and not the full drives correct?

What are the pros/cons to this approach?

Besides the HBA or bare metal approach, what would be a better setup compared to passing in lvm-thin pools

I am ordering a HBA card, so ideally I'd want to use that or just simply move Unraid to bare metal (another server that iam going to rebuild into a NAS). But this won't have for few weeks and I just want to learn few things before then.

If PCI passthrough of a HBA won't work I would passthrough the individual disks as virtual disk like described here instead of working with LVMThin:

Any additional abstraction layer like LVM-Thin would just add unneccessary overhead reducing life expectation of SSDs and performance and makes stuff harder to predict and maintain.

Thank you for linking the correct doc. I was in a bit of a google rabbit hole. I have it all attached now. Going onto my next steps. We can close this as SOLVED!
