proxmox HA ? (lemmy.world)

I recently installed proxmox on two 7050 micro pcs, and set up a third box with PBS.

I had planned to set up a proxmox HA pair with the PBS providing quorum.

After digging into this now I'm questioning doing this at all.

I have some docker instances that are monitoring things with node-red.

I'm thinking about setting up home assistant for controlling stuff.

Is messing with proxmox HA worth it?

The solution seems like an after thought, at least from an installation and configuration aspect.

Anyone using HA?

Using HA a lot but it always depends on your goal. I'm also running several cluster without any HA at my @BoxyBSD@bsd.cafe project. So, it's always about your setup and goal. Talking about HA, we also need to talk about storage. How do you deal with (shared) storage? I one box dies but the VM is on local storage of the dead node, HA won't help you ;) And if you're only about balancing (in a kind of DRS), it's maybe more about ProxLB (https://github.com/gyptazy/ProxLB).

Why are you questioning it? It's pretty reliable. I also use two hosts plus a QDevice for quorum.

I run a 3-node HA cluster. The extra functionality is really nice - live migrations are amazing, and the ability to move guests around gives you a lot of flexibilty.

If your third box supports it, I'd recommend installing proxmox pve alongside pbs on it (pve and pbs can run on the same node), and then create a cluster out of all 3. You don't even have to run any guests on that machine, if you want, but having the flexibility to is nice, along with having everything unified into one cluster.
