Introduction LVM Recovery Kit Administration Guide Introduction The LifeKeeper for Linux Logical Volume Manager (LVM) Recovery Kit provides logical volume support for other LifeKeeper recovery kits.
Introduction Documentation and References The following LifeKeeper documentation is available from SteelEye Technology, Inc.: • LifeKeeper for Linux Release Notes • LifeKeeper for Linux Online Pro.
Requirements Requirements Your LifeKeeper configuration must meet the following requireme nts prior to the installation of the LifeKeeper for Linux LVM Recovery Kit. Please see the LifeKeeper for Linux Planning and Installation Guide for specific instructions regarding the configuration of your LifeKeeper hardware and software.
Overview Overview LVM Operation LVM is currently the standard volume manageme nt product included with all of the major Linux distributions. LVM allows multiple physical disks and/or disk partitions to be grouped together into entities known as volume groups.
Overview As shown in Figure 1, each volume group has one or more logical volum es that depend on it. Conversely, each logical volume must have a volume group on which it depends. A typical LifeKeeper hierarchy containing these two LVM resources looks much like the relationships shown in Figure 1.
Overview return immediately with a success indication. This unneeded attempt to bring the logical volumes in service has no usability impact. LVM Version Support As stated previously, this release of the LVM kit has been tested and is being released only against LVM version 1.
LifeKeeper LVM Hierarchy Creation and Administration LifeKeeper LVM Hierarchy Creation and Administration LifeKeeper LVM hierarchies are created automa tically during the hierarchy creation process for resources that sit on top of logical volumes.
LifeKeeper LVM Hierarchy Creation and Administration 2. On the system which is to be the primary ser ver for your application, create and activate the desired volume groups and logical volumes using the tools provided by the LVM package, and described in the LVM HowTo document referenced in the Documentation and References section above.
LifeKeeper LVM Hierarchy Creation and Administration Using LVM with LifeKeeper Data Replication The LVM Recovery Kit currently supports the u se of LVM “above” LifeKeeper Data Replication (LKDR), but not LKDR “above” LVM.
LifeKeeper LVM Hierarchy Creation and Administration Volume Group Reconfiguration One of the primary benefits of using a logical volume manager is the ability to dynamically resize logical volumes as storage requirements change.
LifeKeeper LVM Hierarchy Creation and Administration Clicking the Resource Configuration button initiates the mechanism for reconfiguring your hierarchy to reflect any modifications to the volume group resource. After a brief pause, an information box will display the volume group modifications that LifeKeeper has detected.
LifeKeeper LVM Hierarchy Creation and Administration After clicking the Reconfigure button, an information box will appear, showing the progress of the reconfiguration procedure, as shown in Figure 6 below. When the process has been completed successfully, the Done button will become enabled.
LifeKeeper LVM Hierarchy Creation and Administration The following two figures show examples of the information boxes that would be displayed during the reconfiguration process when a device partition has been removed from a volum e group.
