[Gluster-users] increase qcow2 image size

I'm doing some tests with proxmox.
I've created a test VM with 100GB qcow2 image stored on gluster with sharding
All shards was created properly.

Then, I've increased the qcow2 image size from 100GB to 150GB.
Proxmox did this well, but on gluster i'm still seeing the old qcow2
image size (1600 shard, 64MB each)

What happens when qemu has to write the 150GB to disk by incresing the
qcow2 image (it's a COW, thus it expand only when needed)

Shouldn't gluster increase the image size?
