Description of problem: Bad sentence structure. Version-Release number of selected component (if applicable): Cluster_Suite_Overview(EN)-5 (2010-02-05T09:51) On Page 5. 1.3.3. Fencing Fencing is the disconnection of a node from the cluster's shared storage. Fencing cuts off I/O from shared storage, thus ensuring data integrity. The cluster infrastructure performs fencing through the fence daemon, fenced. When CMAN determines that a node has failed, it communicates to other cluster-infrastructure components that the node has failed. fenced, when notified of the failure, fences the failed node. SENTENCE STRUCTURE Other cluster-infrastructure components determine what actions to take — that is, they perform any recovery that needs to done. SENTENCE STRUCTURE For example, DLM and GFS, when notified of a node failure, suspend activity until they detect that fenced has completed fencing the failed node. Upon confirmation that the failed node is fenced, DLM and GFS perform recovery. DLM releases locks of the failed node; GFS recovers the journal of the failed node.
Admittedly, "Red Hat Cluster Suite" product in Bugzilla is tempting, but no longer in use (no longer having a standalone position). Rick, thanks for your feedback; this issue is still valid [1,2]. As per the indicated version, flipping to RHEL 5 -- Documentation-cluster and cloning also for RHEL6.

Cloned for RHEL6: [bug 852720]
