Release Notes: This release has significant bugfixes and enhancements, making it a worthwhile upgrade for anyone running R2 CRM-style configurations, or who would like to. An OCF RA for Xen guests and Chinese GUI support have been added. ipfail has been replaced and generalized (limited testing). Master/slave testing and fixes. Significant cibadmin fixes.
Release Notes: GUI management tools were added to simplify the configuration work. Support for monitoring by Common Information Model (CIM) agents was also added. The crm_verify tool was created for checking configuration validity. Support for time and phase-of-the-moon based constraints was added. Many improvements to the handling of resource groups were done. DC order was changed to shutdown after every other node. Several memory leaks and CPU consuming bugs were fixed.
Release Notes: A bug in the ping directive was fixed. A check was added to BasicSanityCheck to check the ping and ping_group directives. cl_status nodestatus was fixed to return success if a node has the status "ping". A memory leak in the CRM's LRM interface code was fixed along with the code that determines which version of the CRM becomes the DC when basic CIB schema versions differ. It now prefers the older version to be DC instead of the newer version.
Release Notes: This release adds date and time-based constraints. It improves the efficiency of netstring encoding. It has new CLI tools for updating the cluster configuration, and cloned resource notification enhancements. A dozen or so minor bugs have been fixed.
Release Notes: This release provides support for monitoring of resources (services) and support for larger clusters that has been tested with 16 nodes. Simple clusters are simple to create, and more complex clusters can take advantage of rule-based resource placement methods to ensure that the cluster does exactly what is desired when failures occur. This release has undergone exhaustive automated testing compiles with zero warnings, and passes a static analyzer with no complaints.
Release Notes: This version features major STONITH code cleanup and debugging, numerous CRM bugfixes, a next generation Heartbeat Resource Manager, and the addition of a Local Resource Manager.
Release Notes: Perl/SWIG bindings were added for some heartbeat libraries. Significant improvements were made to the SAF APIs, and many fixes and enhancements related to Solaris, LVM resource, auto_failback, and watchdog devices were fixed. It now automatically reboots when resources fail to stop correctly. The STONITH device was enhanced, an hb_takeover command was added, and documentation on how to use evlog/TCP for testing without losing messages was included. Split brain, bandwidth, and failure detection time tests were added.
Release Notes: nice_failback was replaced with auto_failback. The ability to use ipfail and hb_standby with active/active clusters was added. ipfail was improved to avoid unnecessary takeovers when networks fail. Fast failure detection (sub-second in well-behaved systems) was added. SAF Application-level data checkpointing capability was added. The APIO FIFOs were removed. New STONITH plugins were added. A new process structure was added. A new internal communications mechanism was added. Several new client API features were added. Tons of small bugs were fixed. The documentation was improved.
Release Notes: This version fixes several IPC bugs, enhances CTS, fixes an authorization memory leak, fixes Solaris portability, fixes behavior with auto_failback on .active/active, changes the API to use sockets instead of FIFOs, adds new apiauth directives to provide authorization, adds Intel's implementation of the SAF data checkpointing API and daemon, adds an IPMILan STONITH plugin, adds an IPaddr2 resource script, and fixes some ldirectord bugs.
Release Notes: ipfail now supports active/active clusters. A fix was made for double resource start. A fix was made for shutdown when auto_failback = legacy. A bugfix was made for messages getting lost if messages were sent in quick succession. A (preliminary?) ordered messaging facility was added.
