Cluster fencing via telnet/ssh fails with SELinux enforcing in RHEL 5 and 6
Issue
- With SELinux in enforcing mode, fencing does not happen when issued through fenced daemon. However, it works with the fence_node command.
- Fence agents using ssh or telnet as the connection method fail when SELinux is in enforcing mode
Environment
- Red Hat Enterprise Linux 5 Advanced Platform (Clustering)
- Red Hat Enterprise Linux Server 6 (with the High Availability Add on)
- SELinux in enforcing mode
- One of the following fence agents:
- fence_alom
- fence_apc
- fence_bladecenter
- fence_drac5
- fence_ilo_mp
- fence_ldom
- fence_lpar
- fence_rsa
- fence_virsh
- fence_vmware
- fence_wti
