Logical Volume Manager

The Logical Volume Manager (LVM) describes a partition variant that is particularly common in the area of Unix and Linux derivatives. The LVM enables the differentiation between hard disks, partitions and file systems, can map dynamic capacity adjustments of partitions (logical volumes) and also generate them across several data carriers. Logical drives created in this way can still be customized in their defined size even after the file system has been created. Various Logival Volume Managers also enable software-based organization for the creation of RAID Arrays (RAID 0, RAID 1 und RAID 5); so-called software raid or SoftRAID. The term can be traced back to setting up a RAID without any additional hardware. The ZFS file system (Solaris) and the free Btrfs file system combine and integrate this SoftRAID component and LVM into the sophisticated file systems.
