Linux LVM is a logical volume manager for the Linux OS that manages disk drives and other data storage devices. Using it, It is possible to create single logical volumes on several physical disks, add and replace them in a running system, resize logical volumes, create various RAID configuration, and so on. You may read more about Linux LVM on this Wikipedia article: Logical Volume Manager (Linux).

LVM volume example

R-Studio automatically detects disks from LVMs and creates their virtual volumes automatically. At the same time, R-Studio gives access to the components of the virtual LVM volumes (hard drives and images).

LVM Volumes in R-Studio

If recognized components of an LVM volume, including disk images, are added to R-Studio later, it automatically adds them to their respective LVM volume.

When an automatically created LVM volume is selected, R-Studio highlights its components. It also highlights the LVM volume that Linux may itself create from the same components.

R-Studio shows the components of the LVM volume on its LVM Components tab.

The LVM Components tab also allows you to manually disconnect or connect the components, for example, if they are such damaged that R-Studio cannot recognize them as parts of a broken LVM volume. Select the object from the drop-down box and click the Connect button. R-Studio displays the objects it recognizes as the components of the LVM volume in blue.
