Jump to: navigation, search


In order to increase application availability in case of hardware or network failures, NetXMS can be installed on two servers, one will be used as primary and the other one is in cold standby. Cluster control logic should migrate the primary IP address to standby server and start the application with database there. Database data are synchronized as a block device via drbd.

Required components

  • drbd
  • corosync + pacemaker
