Comment 1 Tomas Hoger 2008-10-17 05:22:31 EDT

Issue affects fence packages in the Red Hat Cluster Suite for Red Hat
Enterprise Linux 4, and cman packages in the Red Hat Enterprise Linux 5.

Current git version of manual fencing agent is no longer affected, no fifo communication is used any more:

FYI this bug does not affect F9 or cluster-2.03 releases.

Comment 5 Tomas Hoger 2009-11-12 11:27:24 EST

Manual fencing agent is documented as being provided for testing purposed only and should not be used in production environments.  Therefore, there's no plan to fix this flaw in Red Hat Enterprise Linux 4 and 5 and will only be addressed in future product versions.
