Proxmox setup with second node

[natharas]

Hi folks,

I've just purchased an Dell Optiplex 3060 SFF with the intention of running Proxmox on it and pfSense to ultimately replace my home modem / router. It has a 256gb m2 (O/S) and a 128gb SSD (VM's / containers) and an Intel 4 port NIC, it isn't massive storage to say the least.

My main server is a Dell that runs my current Proxmox environment with TrueNAS for storage amongst other VM's. This server contains my two storage pools, first is for media / personal files (NAS) 6 TB total, second is my NVR pool 3.6 TB total and then I have one last disk for VM's and that is 600gb.

With the two devices in mind, I know I can't run HA without a 3rd node, can I do ceph or would that not be viable as well.

Ultimately, I would like to be able to manage both nodes from the one instance (if possible) and also be able to migrate a VM from the Optiplex when needed (aka upgrading storage etc) and vice versa.

I'm open to all suggestions about the Dell Optiplex as I haven't started installing Proxmox on it yet.

Better is m2 for guests and SSD for OS.
U can use a mini PC AS 3.node or quorum. Ceph only with 3 nodes.

Thanks for the reply, you can do quorum on a Synology NAS by chance?

Yes. On most of their devices.

You won't find a preconfigured add on for this. But as long as your Synology can run a Debian container or a VM it should be possible. The requirements for a Quorum Device are really low.

Prepare a Debian environment, including static network and unattended-upgrades and so on. Then follow https://pve.proxmox.com/pve-docs/chapter-pvecm.html#_corosync_external_vote_support

Thank you, I shall look into it as I've had a VM on it before
