Connecting the LVM storage


An LVM storage provides a very high level of flexibility because logical volumes can be easily created or moved around between physical storages attached to a node. We can only store a .raw virtual disk image on an LVM storage. It is not possible to store any OpenVZ templates or containers on an LVM storage.

Getting ready

LVM can be configured using both locally attached disk storage or iSCSI attached devices from a different node. A locally attached LVM must be configured using a CLI. As of Proxmox VE 3.4, it is not possible to configure a locally attached LVM through the GUI.

Note

Note that, by default, the Proxmox installation creates an LVM storage on a local operating system disk to store Proxmox itself.

How to do it…

The following sections show how to add the LVM storage with local devices and create LVM with shared storage as a backend.
