(create a lun bigger than the real storage size), it can be interesting to discard instead zeroing (to free space on storage side). as snapshots currently use lvm volume with same size than the main volume, it can be interesting to have overprovisioning. btw, blockbridge guys have made a nice article here: https://kb.blockbridge.com/technote/proxmox-qcow-snapshots-on-lvm/
