Bugfixes

Add Procedure 5.3, “Performing a Cluster-wide Fresh Installation of a New Service Pack” for customers who prefer a fresh installation even for moving to the next service pack (Fate #325878).

Bugfixes

E.5 July 2018 (Maintenance Update of SUSE Linux Enterprise High Availability Extension 12 SP3) Edit source

General Changes to this Guide
Bugfixes

E.6 September 2017 (Initial Release of SUSE Linux Enterprise High Availability Extension 12 SP3) Edit source

General Changes to this Guide

Configuration changes for corosync (that cannot gracefully be reloaded with corosync-cfgtool -R), and any configuration changes to sbd require restart of the corosync service for the changes to take effect. Restarting the pacemaker service is not enough in those cases.

However, for any changes to /etc/sysconfig/pacemaker, restarting the pacemaker service is sufficient (https://bugzilla.suse.com/show_bug.cgi?id=1050371, https://bugzilla.suse.com/show_bug.cgi?id=1052088).

Chapter 7, Configuring and Managing Cluster Resources with Hawk2

Updated the chapter (including all screenshots) to reflect the software changes in Hawk2. The main changes have taken place in the Dashboard view, described in Section 7.8, “Monitoring Clusters”.

Chapter 12, Access Control Lists

Described how to enable the use of ACLs with Hawk2 in Section 12.2, “Enabling Use of ACLs in Your Cluster”. Added Section 12.4, “Configuring ACLs with Hawk2”.

Bugfixes

E.7 April 2017 (Maintenance Update of SUSE Linux Enterprise High Availability Extension 12 SP2) Edit source

General Changes

Added a new guide, Pacemaker Remote, available at https://www.suse.com/documentation/sle-ha-12. It explains the setup of a cluster with virtual guest nodes or remote nodes, managed by pacemaker_remote. Remote in this context does not mean physical distance, but non-membership of a cluster.

E.8 March 2017 (Maintenance Update of SUSE Linux Enterprise High Availability Extension 12 SP2) Edit source

General Changes to this Guide

Prefer ocf:heartbeat:clvm over ocf:lvm2:clvmd/ocf:lvm2:cmirrord (http://bugzilla.suse.com/show_bug.cgi?id=1030841).

Bugfixes
