+WARNING: The `zero` property for the thin pool must be set or certain 
operations
+for VM images may lead to data corruption! The property is controlled via the
+`allocation/thin_pool_zero` LVM configuration option and is enabled by default.
+Check with `lvs pve/data -o lv_name,zero` which should indicate `zero` in the
+output below the `Zero` heading.
