The LifeKeeper for Linux Logical Volume Manager (LVM) 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 LVM Recovery Kit is different from most other LifeKeeper 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 a LifeKeeper Recovery Kit – for example, creating a hierarchy – are not directly applicable to the LVM Recovery Kit.

The logical volume subsystem within the Linux OS (LVM) has a mirror feature. This feature is not supported by the LVM Recovery Kit.
