Details
LVM RAID is a way to create a Logical Volume (LV) that uses multiple physical devices to improve performance or tolerate device failures. In LVM, the physical devices are Physical Volumes (PVs) in a single Volume Group (VG).
This tutorial will work with the Oracle Linux Volume Manager utilities to create a RAID logical volume and then address a disk failure.
