Virtual NAS

3 years ago by Jason to c/selfhosted

Okay I saw this posted a lot and apparently it is pretty common but why do people virtualize your nas in for example a proxmox server/cluster. If that goes down it gets super hard to get your data back than if you do it bare Metal, doesn't it? Are people only doing it so save on seperate devices or are my concerns unreasonable?

More exciting are the people that host Their firewall/router like OPNSense/PFSense as a VM on their system! 😄

That was me for about 2 weeks until the esxi took a shit. Never again. I basically went "fuck this shit" and bought a ubiquity udm.

I actually did this for a few months until I saved up enough for a decent dedicated firewall appliance. Got a cheap PCIe 2x1GB NIC off Amazon and passed it directly to an OPNsense VM.

Honestly, it wasn’t that bad. The only downside is that that Proxmox server was just an old repurposed desktop PC that was super underpowered, so the VM only had like 2GB of RAM and that ended up being a bit of a bottleneck under load.

I'm doing it with openwrt x86, since I need SQM + wireguard (and at least the former still isn't supported on *sense last time I checked). Works fine in all honesty, and I can reboot the VM much faster than real hardware.

Another vote for virtualized router! I keep set a core VMs on that host where uptime is the highest priority. I've upgraded RAM, downgraded CPU, and eventually switched to an entirely new host with 0 downtime over the past few months. I'd rather not have to wait until everyone else on the network is sleeping before doing any tinkering on the hardware. It's pretty neat to be streaming some video and then live migrate the router to another physical host with 0 interruption.

I'm all for this actually. Though I'd be doing that on a dedicated machine with just pfsense/opnsense on it. Any other way would be kinda dumb right?

I did it for years. The only problem is, if you mess up your opnsense config, you're gonna need to get the keyboard and monitor out.
