two local non-proxmox disks

Experimenting with 2 nodes (+ QDevice) in my homelab. Old PCs, no enterprise-grade hardware. I have an LXC with a bindmount to a local disk (500GB, no shared storage available) on node1. The disk is not setup as a proxmox data store. Data rarely changes on this disk. Similar local disk available in node 2. Hmmm, need to sync those somehow. PVE-zsync can't use recursion, so I can't use that one. Also, I need to reverse the direction of the sync, when I move the container to node2. Perhaps not automatically though, or without deletions...

My idea is to keep the disks in sync using rsync node1->node2, as long as my LXC is running on node1. Of course, the container is unaware of the underlying proxmox host. I'd like to get your feedback on this idea:
Have some kind of file on node1/disk/direction.txt that is excluded from the sync.
Have the same kind of file on node2/disk/direction.txt, also excluded from the sync.
In my LCX, read the file and sync based on the direction read.

I admit it's wacky idea, but I strongly feel that gluster, CEPH and so on would be far too over the top.
What do you think? How did / would you solve this?

I also thought about syncthing installed directly on the proxmox nodes, but I'd prefer to not mess around with them.
Other ideas are welcome.
