I'm thinking about getting started using Docker and an older Raspberry Pi. I'm already hosting a grafana service on it, so It can't be fully dedicated to ha. So curious what everyone is using.

So my plan had been to set up a pair of ProxMox hosts, use Ceph to do the shared storage and use HA so VMs could magically move around if a host died. However, I discovered Ceph and HA need a minimum of 3 hosts. HA can be done if you set up a Pi or some other 3rd host that can act as the 3rd vote in the event of a failure but as I didn't have Ceph I've not bothered trying.

I've read Ceph can work on 2 but not well or reliably.

I might setup a 3rd host some day but it seems a bit of a waste as I just don't need that amount of resources for what I'm running.

And I should have known really, I've a bit of a background in VMware, albeit at the enterprise level so I've never had to even think about 2 or 3 node clusters.

Ah, ok.

Yep, I'm in a similar situation... I have a few VMs, but not enough for lots of failover infrastructure... (redundant switches, etc)

I was thinking you might be just cloning 1 device to the other or something.

Oh I have a pair of D-Link switches (again off ebay) that are stacked together. My router, NAS and both ProxMox hosts have LACP connections to both. And my home WiFi is a couple Aruba IAPs, one on each switch. So if I lose a switch then most things will keep running.

You can do HA in Proxmox with ZFS replication instead of Ceph. Third device something else as you said. It's what I'm doing.

Thanks, I'll look into it.
