LVM
From Glee
Overview
The key to the initial understanding of LVM is understanding the 3 basic objects :
- PV (physical volume) : Partitions of type 8e which will be used for LVM.
- VG (volume group) : Groups where LVs will be created, which consist of one or more PVs grouped together.
- LV (logical volume) : The smallest LVM unit, the "usable" one, which is a flexible block device to be used like any other disk or partition.
