1.195. pacemaker

Updated pacemaker packages that fix various bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
Pacemaker is a high-availability cluster resource manager with a powerful policy engine.
Bug Fixes
BZ#668466
The pacemaker packages have been upgraded to upstream version 1.1.5, which provides a number of bug fixes over the previous version.
BZ#627626
Due to missing Cluster Resource Manager (CRM) scripts, an attempt to run the crm utility caused the following message to be presented to a user:
        crm_standby not available, check your installation
This update re-includes the "crm_master" in the packemaker package, and adapts the crm utility not to require the "crm_standby" and "crm_failcount" scripts, so that the above error message is no longer displayed.
BZ#684825
In a cluster environment managed by both Pacemaker and the CMAN cluster management subsystem, frequent leaving and joining of a node could cause Pacemaker's quorum view to be incorrect. This update applies a patch that addresses this issue, so that the leaving and joining of a node no longer causes Pacemaker's quorum view to be different from CMAN's.
BZ#684838
Previously, rebooting a node in a CMAN managed cluster could cause the fencing daemon to keep the "fenced:default" CPG group on the remaining nodes, leaving the cluster in an inconsistent state. With this update, an upstream patch has been applied to address this issue. As a result, when a node is rebooted and leaves a cluster, the cluster resources correctly run on remaining nodes.
Enhancements
BZ#676286
When using the fence_ipmilan fencing agent, Pacemaker now accepts "diag" as a valid per-device stonith action. With this action enabled, a fenced node receives the "DIAG" signal and creates a dump for diagnostic purposes.
Note that Pacemaker provides the following functionality, and is now the preferred application to perform these tasks:
BZ#310361
Pacemaker provides support for a time-based resource control. This allows system administrators to define the time a resource is down.
BZ#449833
Pacemaker supports time-based resource control. This allows system administrators to define the downtime of individual resources.
BZ#449835
Pacemaker allows users to manually start or stop cluster resources. This enables system administrators to perform maintenance tasks on individual components within a service.
All users of pacemaker are advised to upgrade to these updated packages, which fix these and other bugs, and add this enhancement. Note that pacemaker is considered a Technology Preview in Red Hat Enterprise Linux 6.
