Use either proxmox or unraid. Don't stack.

They are both great in their own respects but you need to choose what works for you and your hardware.

Up until recently I liked unraid due to being able to use multiple disks with different capacities. You don't really have that freedom with proxmox.

If you virtualize unraid, unraid wont have direct drive access - you can get around this by getting an HBA card and forwarding that to the unraid VM. Others have mentioned that proxmox doesn't have docker support, I personally run docker containers within lxc boxes on proxmox. There are solutions to make managing containers easier, like portainer, if you want to go down that route.

Oof. No.

Wouldn't do it for a litany of reasons, but the main being that it's not meant for such things. You want it to be as close to the OS and drivers as possible. Anything getting between Unraid managing the disks is overly complex, and asking for trouble. What happens if the container dies? What happens if the container gets OOMkill'd?

If you're not going to use it to manage your disks, then I guess no issues, but there's better suited software for such things.

Isn't Unraid also a VM host of sorts?

It's understandable that you want to take your virtualization-capabilities to the next level but I also don't see the appeal of containerizing unraid like many others here. I started using unraid last autumn and to me it really is about being able to mix drive sizes. It's a backup to my main server's ZFS pool so (fingers crossed) I don't even really worry about drive failures on unraid. (I have double parity on ZFS and single parity on unraid.)

Anyways my point is I started out with 8 SATA slots plus an old USB-based enclosure with i set to JBOD mode and that was a pretty stupid idea. unraid couldn't read SMART data from those USB drives. Every once in a while one of the drives would suddenly show up as having an unsupported partition layout. Couple weeks ago all 5 drives in the enclosure started showing up as unusable. So as you can imagine I dropped that enclosure and now am working solely off the 8 internal slots. I'd imagine that virtualizing unraid's disk access might potentially yield similar issues. At least the comments of people here remind me of my own janky setup.

I've been running Unraid on top of Proxmox for over 3 years. No problems whatsoever. I initially bought a RAID controller to directly pass the drives to the UnRAID VM. Another option is to passthrough the SATA controller of your motherboard (only possible if you don't use them on the host).

I documented the process on my blog (it's quite straightforward): https://simplyexplained.com/blog/howto-virtualize-unraid-on-proxmox-host/

Proxmox doesn't run docker containers. You can probably install docker to make it run them, but it's not supported.

I also wouldn't run unraid on a virtual disk just to provide storage. Personally, I have one almalinux VM running on Proxmox that runs all my containers and has a big virtual disk to store my media.

I am in the same boat currently and thinking about how I can migrate my stuff over without having a 1 month downtime EDIT: after reading all the comments I'm still not sure if I should do it or like I said even how. I love my unraid it fits me well however I think I also have fallen in love with proxmox

I wouldn't, you'll lose a lot not having it manage the disks such as using dissimilar disks for the array and having it spin down unused disks. You might be able to pass disks through so the unraid VM can manage them directly, but it might be harder than I'd personally want to deal with.

If you aren't running VMs much. Truenas scale I believe can do docker well. I've seen a lot of people put that in a VM on proxmox with disks passed through to be used as the NAS portion.

If you want to move to Proxmox then I say give it a go.

Maybe just keep what you have running and set up another machine to have a play. If you like it, then stick it on your main machine and work out how to replace everything, could be a fun project for you.

I use Proxmox and have Open Media Vault as my NAS. I use SMB/CIFS to share the drives and have a share that Proxmox can use for daily backups, as well as having backups on the main SSD every week. I need to off-site backups but I haven't researched that yet.

I have a Debian VM that runs Docker and have everything running on that except OMV and Home Assistant. I have another Debian VM that I spin up to try things out.

RAM-wise I'm hitting about 12gb so if you have something with 16 lying around you can easily try out most of what you have running already, and if you don't have anything to run it on you're talking under £100 for a mini PC.

Give it a go, I'm sure you can come up with something to run on a mini pc anyway

If you want to just use it exclusively as a Nas, then why not truenas?

I have a unRAID server but the nas part is nowhere as good as truenas (slower, worse ad integration)

Main issue with virtualization is the bootable USB with the serial number that's used as DRM
