When using iSCSI with Proxmox, it is generally used as LVM over iSCSI.
In this case, LVM is provisioned using Thick provisioning, not Thin provisioning.
Note that Snapshots are provided as snapshot-as-volume-chain, which differs from typical Snapshots.

Hi @Jianming , also note that your backend storage may provide some level of thin provisioning at the SAN layer, independent of the iSCSI and LVM.
