Issue

  • HA configuration with 3 node controller in RHOSP6(Foreman).
  • First controller node shows following output when use chkconfig --list.
 rsync-galera:   on
  1. What is rsync-galera? What purpose is this service?
  2. If the node which enables the service fails, can other nodes work normally?
  3. Do we need to enable 'rsync-galera' in other controller nodes?
