On one of my podcasts, the subject was homelab backup. One of the hosts mentioned that he didn't need high-availability features in his 2-node
Proxmox cluster because he ran his VMs from NFS.

Wait, you can do that?

I run my VMs out of local storage on 2 nodes. I'm not running anything production-like, so if I lost a node (which I did recently) then going
back to a backup or a snapshot onto the remaining node is fine.

Leaving the VM on NFS means if I lost a node, I could just recreate a
node on the remaining node and point to the VM disk in NFS. Interesting.

I have an NFS share on Synology mounted on both nodes (they back up
there) so I tried migrating the disk volume to it, and it works! A
little slower than local, but certainly usable.

The only issue is the noise. My Synology is chattery, and when hitting
the BBS VM over NFS, it makes a lot of noise.

I have a plan to migrate my NFS into a storage area, I'm also thinking
about buying the 10GB ethernet adapter for Synology and connecting it
and my primary node together over 10GBe or 2.5GBe - whichever cost I can stomach for the switch and a couple of PC adapters.

Shared storage for hypervisors is a well-established approach - VMware, Proxmox, etc have been doing it for years. It makes VM migration, HA/failover and moving workloads between hosts much easier since the disks are already accessible from both nodes.

NFS on a Synology is a perfectly reasonable homelab solution. If you're finding it a bit slow or noisy, 10GbE (or even dedicated 2.5GbE for storage traffic) can help a lot. SSD cache / SSD-backed storage can also reduce the chatter.

Ceph is another good shared storage option if you ever want to go more distributed and remove the single NAS dependency, though it's generally a bit heavier to run/manage than simple NFS.

2-node PVE cluster??? But if one goes down you won't have quorum - you have to add a 3rd for sure! I use a Raspberry Pi, unless I have a proper 3rd PVE node... 3 are needed for quorum, baby!!

Leaving the VM on NFS means if I lost a node, I could just recreate a
node on the remaining node and point to the VM disk in NFS. Interesting.

I also didn't realize I could use NFS shares as VM/LXC drives - super cool, but I don't think as fast as proper HA disks...

Unless you're doing proper HA stuff, quorum prolly isn't _that_ important, but yeah you don't need another "node" to make quorum, just a pi will suffice.

Yeah tho you prolly wouldn't wanna use it as the only vm disk source, maybe just a second vm disk to back stuff up in the guest perhaps, unless it was fast NFS with SSD backing it, 10Gb/s fast would probably be ok. If I wanted to make it full on, I would definitely have a ceph cluster for the vm disks and just use the hypervisors for the compute.

Yes, if you mean what I think you do.

I have a Virtualbox instance running an older version of linux. Virtualbox runs on the local machine but the image it fires up lives on my local
network NFS fileserver.

:P I disagree - even if we're not super worried about the systems, I always want to know my PVE won't go offline if one of the nodes dies. :P

Done it for years with VMWare, knew about ceph, didn't think about NFS.

also reduce the chatter.

There's a 10GBe adapter for the Synology, it wouldn't take a lot of work
to create a faster network for the VMs and NAS. What I really need to do
is wire a shelf in my storage area with ethernet and move the NAS out of
my office. It'd be cheaper than replacing the drives nowadays and quiet
my office down a lot.

Ceph is another good shared storage option if you ever want to go more distributed and remove the single NAS dependency, though it's generally
a bit heavier to run/manage than simple NFS.

I've thought about taking my Pi4 and making it a 3rd node. Wish it had
enough horsepower to run PBS.

The one time I had a node failure, I just restored the BBS from backup
to my remaining server. Wasn't a huge effort.

My PVE quorum node is a Pi4 - it happily serves its 'quorum' purpose AND runs a Pi-Hole and Pi-VPN nicely...

For my PBS, I just use some 200X Dell tower - enough SATA to handle large backup drives and I used its GPU card for something else...

The last time I ran PBS, the node it was on crashed. Wasn't sure if all
the metadata was stored in the backup, so if I fired up a vanilla PBS
node and pointed it to the backup repo, if it would be able to restore
the system.

The only thing I really care about backing up is the BBS, and backing up
the files section is where the de-dupe would come in handy.
