Move UnRaid from metal to Proxmox (lemmy.ml)

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?

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

It's the production vs development issue. My advice is the old tech advice. "If it's not broken don't try to fix it"

Modified into a separate proxmox development environment. Btw proxmox is perfect for this with vm and container snapshots.

When you get a vm or container in a more production ready state then you can attempt migrations. That way the users don't kill you :)

That is true, I mean I mostly only use my homelab except some game servers that I am running. And you are totally right. Only reason why I want to run proxmox or in general why I have a homelab is to learn more about servers and self hosting. I am currently in the first year of my apprenticeship and I have learned so much since I got my server up and running 😄 and I think I can learn a lot more when I am using proxmox

Yup. I think I'm going to go the 2 servers way after all, but not before I try doing it in one, because, we'll, why not? Isn't that what home labs are about? 🤣🤣🤣

[–] Mixel@feddit.de 0 points 6 months ago

Please keep me up to date what you try and how you are trying to migrate it over! :D and obviously good luck

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?

[–] jjlinux@lemmy.ml 0 points 6 months ago (1 children)

Yeah, UnRaid does all of that, but from my very basic testing of ProxMox in an old computer, the VM management is much better than in UnRaid. The same goes for VLAN awareness with just 1 nic.

I'm in no way unsatisfied with UnRaid, but I watched a video by Christian Lempa doing something similar, only with TrueNAS instead of UnRaid, which is what got my brain thinking about all these potential options.

[–] just_another_person@lemmy.world 0 points 6 months ago (1 children)

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.

[–] jjlinux@lemmy.ml 0 points 6 months ago (1 children)

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?
