DRBD is a distributed replicated block device. It 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.

These packages are 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.

WARNING: These packages conflict with drbd83. Since the configuration changed starting from DRBD 8.4 we cannot automatically obsolete 8.3 packages by 8.4 packages.
