Linux LVM is a logical volume manager for the Linux OS that manages drives and other data storage devices. Using it, It is possible to create single logical volumes on several physical drives, add and replace them in a running system, resize logical volumes, create various RAID configuration, and so on.

R‑Studio detects drives from LVMs and creates their virtual volumes automatically. At the same time, R‑Studio gives access to the components of the virtual LVM volumes (drives and images).
If recognized components of an LVM volume, including drive 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.
R‑Studio shows the components of the LVM volume on its LVM Components tab.
R‑Studio shows broken virtual LVM volumes in pink.
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.
You may immediately switch to the LVM volume configuration that R‑Studio believes most probable by clicking the Reassemble button.
