# Reconfiguring Corosync and Pacemaker for a server

Contents

Pacemaker and Corosync configuration is required for each server if you are creating or expanding a high-availability file system. Intel® Manager for Lustre* software automatically configures Corosync and Pacemaker for each managed HA server that you add, so that manual configuration of Pacemaker and Corosync should not normally be required. See Add one or more HA servers.

An administrator may need to reset or configure Pacemaker or Corosync when performing maintenance on a server, altering the server's configuration, or troubleshooting problems with those services. See Pacemaker configuration and Corosync configuration for more information.
