RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Pokorný [poki] 2012-08-29 11:55:41 UTC 
+++ This bug was initially created as a clone of Bug #607344 +++

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.

Comment 1 Ruediger Landmann 2013-06-04 23:07:18 UTC 
This is a component only relevant to RHEL 5.x. The new component for RHEL 6.x for this manual is doc-High_Availability_Add-On_Overview.
Comment 2 Steven J. Levine 2014-06-03 20:48:15 UTC 
Reassigning to me since I think I'm going to be maintaining this document henceforth.
Comment 3 Steven J. Levine 2014-06-06 17:29:05 UTC 
I have made this fix to the working draft of this document for RHEL 6.6, but if this is the only update for this release we may not update this particular document for RHEL 6.6.

This is the build:
Red_Hat_Enterprise_Linux-High_Availability_Add-On_Overview-6-web-en-US-1-8.el6eng
Comment 4 Steven J. Levine 2014-06-06 18:15:47 UTC 
No, this is the build:

Red_Hat_Enterprise_Linux-High_Availability_Add-On_Overview-6-web-en-US-1-8.el6eng
