Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

2.8. Red Hat Cluster Suite and SELinux

Red Hat Cluster Suite supports SELinux states according to the Red Hat Enterprise Linux release level deployed in your cluster as follows:
  • Red Hat Enterprise Linux 5.4 and earlier — disabled state only.
  • Red Hat Enterprise Linux 5.5 and later — enforcing or permissive state with the SELinux policy type set to targeted (or with the state set to disabled).


When using SELinux with Red Hat Cluster Suite in a VM environment, you should ensure that the SELinux boolean fenced_can_network_connect is persistently set to on. This allows the fence_xvm fencing agent to work properly, enabling the system to fence virtual machines.
For more information about SELinux, refer to Deployment Guide for Red Hat Enterprise Linux 5.
