Thanks a lot, Lindsay! Appreciate the help.
It would be awesome if you could tell us whether you
see the issue with FUSE as well, while we get around
to setting up the environment and running the test ourselves.

Yes, you need to add a full replica set at once.
I don't remember, but according to my history, looks like I've used this :
gluster volume add-brick VMs host1:/brick host2:/brick host3:/brick force
(I have the same without force just before that, so I assume force is needed)
Ok, I did a:
gluster volume add-brick datastore1 vna.proxmox.softlog:/tank/vmdata/datastore1-2 vnb.proxmox.softlog:/tank/vmda ta/datastore1-2 vng.proxmox.softlog:/tank/vmda ta/datastore1-2
I had added a 2nd windows VM as well.
Looked like it was going ok for a while, then blew up. The first windows vm which was running diskmark died and won't boot. qemu-img check shows the image hopelessly corrupted. 2nd VM has also crashed and is unbootable, though qemuimg shows the qcow2 file as ok.
I have a sneaking suspicion its related to active IO. VM1 was doing heavy io compared to vm2, perhaps thats while is image was corrupted worse.
rebalance status looks odd to me:
root@vna:~# gluster volume rebalance datastore1 status
Node Rebalanced-files size scanned failures skipped status run time in h:m:s
--------- ----------- ----------- ----------- ----------- ----------- ------------ --------------
localhost 0 0Bytes 0 0 0 completed 0:0:1
vnb.proxmox.softlog 0 0Bytes 0 0 0 completed 0:0:1
vng.proxmox.softlog 328 19.2GB 1440 0 0 in progress 0:11:55
Don't know why vng is taking so much longer, the nodes are identical. But maybe this normal?
When I get time, I'll try again with:
- all vm's shutdown (no IO)
- All VM's running off the gluster fuse mount (no gfapi).
cheers,
