Systems Infrastructure – Volume Management

What is Volume Management?

Volume management creates an abstraction layer between the operating system and the physical storage medium. This allows the systems administrator to grow or shrink the storage space on a logical disk or partition when either additional disk space is needed, or, when a predetermined storage volume is not using as much disk space as initially allocated. A volume management system can be built on top of SAN blocks or a set of RAID disks for performance and redundancy. Most volume management systems will have "snapshot" functionality that will enable a backup of a filesystem where all files within the file system are in a consistent state.This allows the storage system to incur the overhead of the backup operation and alleviates any file locking contention between application software the backup system.
