Benefits of Logical Volume Management |
Logical Volume Management provides benefits in the areas of disk management and scalability. It is not intended to provide fault-tolerance or extraordinary performance. For this reason, it is often run in conjunction with RAID, which can provide both of these.
By creating virtual pools of space, an administrator can assign chunks of space based on the needs of a system's users. For instance, he can create dozens of small filesystems for different projects and add space to them as needed without (much) disruption. When a project ends, he can remove the space and put it back into the pool of free space. He can even create a logical volume and filesystem which spans multiple disks. Contrast this with the administrator who just slices up a hard disk into partitions and places filesystems on them. He cannot resize them or span disks.
