Cman is not able to start when using unfence with fence_brocade

Solution Verified - Updated -


  • Red Hat Enterprise Linux 6.1 - 6.5
  • fence-agents package prior to fence-agents-3.1.5-48


Cman is not starting when using unfence in cluster.conf in combination with “fence_brocade” fencedevice.
If the unfence part is commented, the cman starts with no problems at all.

Snippet of cluster.conf:

                <clusternode name="node1" nodeid="1">
                                <method name="san">
                                        <device name="sanfence" port="1"/>
                                <device action="on" name="sanfence" port="1"/>


  • The fence_brocade accepts only following parameters for action prior to RHEL 6.6, prior to fence-agents-3.1.5-48.el6
        <action name="enable" />
        <action name="disable" />
        <action name="status" />
        <action name="metadata" />

If you are using action="on" the cman will not start.

  • Please use action="enable" instead action="on" to resolve this issue.

  • RHEL 6.6+ with fence-agents-3.1.5-48.el6 or greater.

the "enable" action no longer works, and should be reverted to "on". This package was re-based in 6.6 to use python, and brought in line with our standard python fence agents which use "on" and "off" as options.
