DRBD mirrors a block device over the network to another machine. Think of it as networked raid 1. It is a building block for setting up high availability (HA) clusters.
This packages includes the DRBD administration tools and integration scripts for heartbeat, pacemaker, rgmanager and xen.
These packages are also compatible with the upstream packages from Linbit, however we decided to move the heartbeat, pacemaker, rgmanager and xen integration scripts directly into the drbd84-utils package, which properly obsoletes those packages. Please uninstall the drbd-km-<kernel> packages to avoid any conflicts.
