I have a trusty UnRaid server that has been running great for almost 3 years now, with some kinks and headaches here and there, but mostly very stable. Now I'm entertaining the idea of setting that box up with ProxMox, and running UnRaid virtualized. The reason being that I want to use UnRaid exclusively as a NAS and then run all dockers and VMs on ProxMox (at least that's how I'm picturing it). I would like to know your opinion on this idea. All I have is Nextcloud, Immich, Vaultwarden, Jellyfin, Calibre, Kavita and a Windows VM I use to update some hardware every now and then. I mainly want to do that for the backup capabilities in ProxMox for each instance. Storage is not a concern, and I have 64GB of ECC Ram running in that box. What are the Pros and Cons, or is it even worth it to move all this to ProxMox?
There's the question of "CAN I do this?" vs "SHOULD I do this?". I don't think abstracting your main storage handling software away from where it definitely needs to be is going to net you anything positive, but add more issues and complications.
I'm sure you can find videos of people running drivers out of containers just because it's possible. Should you though? Nope.
I do have the advantage of having a mirror of my server 2.5K miles away in my brother's house. That's probably why I'm thinking about being so candidly careless.
I appreciate the great advise. But now I'm willing to take one for the team and come back with either am horror story or an epic win.
BRB.
Have you considered the increase in disk io and that hypervisor prefer to be in control of all hardware? Including disks...
If you are set on proxmox consider that it can directly share your data itself. This could be made easy with cockpit and the zfs plugin. The plugin helps if you have existing pools. Both can be installed directly on proxmox and present a separate web UI with different options for system management.
The safe things here to use are the filesharing and pool management operations. Basically use the proxmox webui for everything it permits first.
Either way have fun.
That sounds like a great idea.
At the moment I am using Openmediavault as a VM within proxmox - I pass my HDDs through to this VM. Openmediavault let's me do all the stuff I want to: Share folders via SSH, NFS and raid-management.
Do you know if I can do the same with proxmox directly? Do you maybe have a link where this way is described in detail?
At its core cockpit is like a modern day webmin that allows full system management. So yes it can help with creating raid devices and even lvms. It can help with mount points and encryption as well.
I do know it can help share whatever with smb and NFS. Just have a look at the plugins.
As for proxmox it's just using Debian underneath. That Debian already happens to be optimized for virtualization and has native zfs support baked in.
