Logical Volume Manager Recovery Kit Notes and Restrictions

The following notes and restrictions apply to this version of the Logical Volume Manager Recovery Kit.

Volume Group Activation

In the current LVM implementations, when a volume group is activated, all logical volumes associated with that volume group are also activated automatically. For LifeKeeper, this means that there will be times when a logical volume is active despite the fact that its associated resource instance is still marked as being Out-of-Service (OSU). In a typical failover or switchover operation, LifeKeeper will attempt to bring the logical volumes in service immediately after the volume groups anyway, and the resulting calls to the restore script will return immediately with a success indication. This unneeded attempt to bring the logical volumes in service has no usability impact.

LVM mirroring functionality is not supported

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