Why use Logical Volume Management?●●●Agility●●●Dynamically adjust storage configurationGrow, shrink or relocate your data/filesystemsAggregate or subdivide devices as neededPerformance●Striping across multiple devicesFault Tolerance (redundancy & resiliency)● RAID 0, 1, 5, 6, 10●Snapshots
Building Blocks of Storage ManagementFile-systemsLogical Volume(LV){{Formatted LV's become filesystemsA virtual storage device that may span multiple physicaldevices. Allocatable chunks (PEs) are assembled into“Logical Extents” that form the addressable space.Volume Group(VG){A collection of Physical Volumes that are divided into discreteallocatable chunks called “physical extents” (PEs).Physical Volume(PV)Physical Device{{An LVM concept that identifies physical devices for LVM use.Disks (IDE [hda], SCSI, SATA & SAS [sda], etc...)Partitions (ex: hda1, sda1, cciss/c0d0p1, etc...)LUNs (FCOE, SAN, etc...)loopback
