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).
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).
R-Studio shows broken virtual LVM volumes in pink.
If recognized components of a virtual LVM volume are added to R-Studio (including disk images), R-Studio automatically adds them to their respective virtual LVM volumes.
When virtual LVM volume components are such damaged that R-Studio cannot recognize them as components of broken virtual LVM volumes, you may add them manually. Right-click the required virtual LVM volume, select Add missing disks on the context menu and select the required object(s) on the Add missing disk dialog box.
You should place the objects on their correct places.
