DRBD Management Console

DRBD Management Console is a Java application that aims to ease the process of managing cluster systems that are based on DRBD and Heartbeat.

Administrators

This program is intended for administrators who understand the concepts and details of DRBD and Heartbeat. But in many smaller shops they have lots of other tasks than DRBD and Heartbeat administration.

Every time there is something to do with the DRBD/Heartbeat setup administrators find it hard to remember the right commands, since they use them so seldom.

Working principle

The DRBD management console does not require any kind of agent or client code on the cluster nodes. It uses ssh access, as you do when you work with your servers.

Features:

• Wizard driven installation/update of DRBD/Heartbeat on you cluster nodes
• Wizard driven creation of Heartbeat configuration file ha.cf
• Presents NICs and block devices
• Graphical representation of complete DRBD status
• Create new DRBD resources in the DRBD overview
• Actions on DRBD resources available as context menu in the DRBD status view
• Graphical representation of Heartbeat resources and their constraints
• Resource states and the node they run on included in the graph
• Context menus with actions on Heartbeat resources
• Text console view of all commands DRBD MC issues
