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.
