Hi, I have ubuntu installed on my nuc and hassio running well in portainer. I would like to add features of a Nas with additional HDD on usb. I was looking at OMV but can o ly find ways of installing Hassio on that not the other way around. I don’t really want to mess with my hassio install as it’s working well at the moment. Is it possible to add nas to the current config or do I need to start again?
Thanks in advance
I think the easiest would be to go with proxmox way.
Before of course, you have to backup your hassio and restore it later.
So there is no real way to add any nas software into a docker container in portainer to save messing with it all? I have other things on the ubunto install like retropie so I can use it for retro gaming as well as hassio to make the most of the nuc

Well, you can try to run docker image with ubuntu image and try to install the OVM there. Might work, but I have never did this way.
