The Linux Cluster Management Console (LCMC) is an application that eases the burden of managing your Corosync/Heartbeat, Pacemaker, and DRBD-based cluster systems. It does not require any kind of agent or client code on the cluster nodes, instead using SSH.

Changes:
Using Filesystem RA with DRBD proxy was fixed. PV/VG displays are not called periodically anymore, and zooming in graphs was fixed.
