Abstract

Use the Virtual Data Optimizer (VDO) feature in Logical Volume Manager(LVM) to manage deduplicated and compressed logical volumes. You can manage VDO as a type of LVM's Logical Volume (LV), similar to LVM thin-provisioned volumes.
You can deploy VDO on LVM (LVM-VDO) to provide deduplicated storage for block access, file access, local storage, and remote storage. You can also configure a thin-provisioned VDO volume to avoid the physical space of the VDO volume being 100% used.
You can manage the VDO volume by using the LVM tools after importing the VDO volume into LVM.
