Logical Volume Manager Recovery Kit Administration Guide

The LifeKeeper for Linux Logical Volume Manager Recovery Kit provides logical volume support for other LifeKeeper Recovery Kits. Thus, LifeKeeper-protected applications can take advantage of the benefits offered by the Logical Volume Manager, including simplified storage management and the ability to dynamically re-size volumes as needs change.

The Logical Volume Manager Recovery Kit is different from most other Application Recovery Kits in that it is never used alone but always as a dependency of another LifeKeeper resource. As such, many of the operations typically associated with an Application Recovery Kit – for example, creating a hierarchy – are not directly applicable to Logical Volume Manager Recovery Kit.

The LVM within the Linux OS has a mirror feature. This feature is not supported by the Logical Volume Manager Recovery Kit.
