here the patch series:
https://lists.proxmox.com/pipermail/pve-devel/2024-August/065201.html
The idea is to create a lvm volume smaller than the real qcow2 size,
qemu is sending an event when the used space reach a threshold,
then a daemon should resize the lvm volume by increment.(1GB for
example),
until the next threshold reach....
The only complex thing is to manage some kind of queue in this daemon
and manage
lvm cluster lock, as we can't resize multiple lvm volume at the same
time.
(Not sure if it need a central daemon, or a distributed daemon on each
node with a shared queue in /etc/pve ...)
