I'm considering running Unraid as a VM on Proxmox, mainly to manage Docker containers. I don't plan to use any other Unraid features. However, I have a few concerns and questions regarding how Unraid's reliance on a USB drive might affect Proxmox's High Availability (HA) feature.

 

For some background, I’ve been using Unraid on bare metal for a long time and recently switched to Proxmox. While I enjoy the flexibility of Proxmox, I still miss Unraid’s easy-to-use interface for Docker management.

 

1. Since Unraid runs from a USB, will this cause issues with Proxmox's HA if the VM needs to be restarted or moved to another node? My understanding is that Proxmox HA might struggle with the USB passthrough.
2. Is there any known workaround or best practice to manage this? For example, would it be feasible to run Unraid from a virtual disk instead, while keeping the USB just for licensing?

 

I'd appreciate any suggestions or guidance from those who have experience with running Unraid in a Proxmox VM, especially when it comes to minimizing potential HA issues.

 

Thanks in advance!

Running Unraid as a guest is not officially supported. It's not forbidden, but any issues you encounter will need to be sorted out by collaboration with other like minded users, if you feel there is an issue with Unraid you will be asked to recreate that issue running baremetal before Limetech will look at it.

 

With that in mind, I moved your post to the specific area on these forums where running Unraid as a guest is discussed. Hopefully someone familiar with your questions can help you out, and you can browse around to see what others have dealt with.
