Sure, but that's transparent, mounting localhost:/VMs should still work
fine if I'm right. It'll ask localhost for the bricks then talk to them

That's really no big deal. I was already pretty sure of it but since I've
started graphing read and write speeds on our gluster volumes it's very
clear that VMs basically don't read from disk, everything is in cache in ram.
I sometimes litteraly have hours without any actual read operations on the
volumes even with 20 VMs running on it. So I really don't mind the remote
access there :)

And writting won't benefit much in having data on the local drive since
you have to write to all the bricks at once. I'll lose 1/3 of the
bandwith for the machines running on those new proxmox nodes, but that's
really not a bid deal, bandwith never was the problem, latency is, and
this solution won't change latency at all.

Or am I missing something key here ?
