I use PVE 9 with an DELL ME4 iSCSI Storage. This storage is thin provisioned but don't handle unmap command. To avoid data loss zeroing out removed disks is enabled.
storage.cfg
This task don't check if the disk is enabled and writes into RAM until is full.
zero-out data on image vm-28999-disk-2 (/dev/vg_rtx2st001_pve001/del-vm-28999-disk-2)
/dev is a RAM FS and I think before deletion the LV isn't enabled and the fill process needs to avoid creating files.
