+ Version 2.0.3 - Bug fixes and significant new features.
+ Management Daemon/Library and GUI client
+ provide a management library for manamgement daemon and CIM provider
+ provide a management daemon and a basic GUI management tool
+ CIM enablement
+ CIM (Common Information Model) enablement - works with
sblim-sfcb, OpenWBEM, and Pegasus CIMOMs
- not yet compiled into our binary RPMs because of dependencies
+ CRM (Cluster Resource Manager) General
+ All shutdowns go via the PE/TE - preserves inter-resource ordering
+ Support for future changes to the CIB (depreciation of cib_fragment)
+ Overhaul of IPC and HA channel callback logic
+ Many improvments to the quality and quantity (reduced) of logging
+ CRMd
+ Timerless elections - when everyone has voted we're done
+ Use the replace notification from the CIB to re-update our copy with
our view of our peers.
+ Reliably detect if the LRM connection is still active.
+ Elections
+ newer versions defer to older ones in DC elections
(opposite of current behavior)
+ this means that only once the complete cluster has been upgraded will
we start acting like the new version and accept new config options
+ it also means newer PE's and TE's (the most complex pieces) don't need
"act like the old version" options and can rely on all slaves being at
least as up-to-date as they are
+ people can run mixed clusters as long as they want
(until they want the new PE features)
+ new DCs only update the version number in the CIB if they have a
higher value
+ nodes that start and have a lower version than that stored in the CIB
shut themselves down (the CRM part anyway)
+ this prevents an admin from introducing old nodes back into an upgraded
cluster. It probably doesn't fully understand the config and may not
support the actions the PE/TE requires.
+ CIB (Common Information Base daemon)
+ Make sure "query only" connections cant modify the CIB
+ Periodically dump some stats about what the CIB has been doing.
+ Verify there are no memory leaks
+ Performance enhancements
+ Prevent a single CIB client from blocking everyone else
+ Clients Can be notified of full CIB replacements
+ record_config_changes option in ha.cf for those worried about
the amount of logging. Defaults to "on".
+ suppress_cib_writes CIB option replaced with in enable_config_writes ha.cf
(enable_config_writes to be removed in 2.0.4)
+ Never write the status section to disk
+ Check permissions for the on-disk CIB at startup
+ Dont trash unreadable on-disk CIBs
+ Fix for updates made against the whole CIB (not just one section)
+ PEngine (Policy Engine)
+ Many improvements to the handling of resource groups
+ Support "anonymous" clones
+ Fix stonith ordering
+ Order DC shutdowns after everyone else's
+ Support short resource names (for group and clone resources)
+ The ordering and colocation of grouped resources is now optional
+ Support probing new nodes for active resources.
+ All "probe" actions are controlled by the PE.
+ No resource may be started until the probing is complete.
+ Do not probe for resources we know to be active on unprobed nodes
+ When looking for monitor ops, only mark it optional if it was already
active on the node we're interested in.
+ Detect changes to class/type/provider/parameters and force a restart
of the resource
+ New record_pengine_inputs option in ha.cf for those worried about
the amount of logging. Defaults to "on".
+ Differentiate between config and processing errors
+ reduces the frequency that we need to log the complete CIB
+ Make notify for master/slave work
+ New CIB option: stop_orphan_actions (boolean)
If a resource is no longer defined, we can optionally stop it
+ New CIB option: stop_orphan_actions (boolean)
If a monitor op for a given interval is no longer defined, we can
optionally stop it
+ Add support for time and phase-of-the-moon based constraints
+ Improved failure handling: avoiding false positives
+ Always create orphaned resources - so they show up in crm_mon
+ Do not require sequential clone numbers starting at 0
+ TEngine (transition engine)
+ Detect old stonith ops
+ CLIs (Command Line interfaces)
+ Create a --one-shot option for crm_mon
+ Switch a number of CLI tools to use the new syncronous connections
+ Log errors to stderr where they will be seen and therefore useful
+ Support migration and un-migration of resources and resource groups
+ Create crm_verify for checking configuration validity
+ Simplify the passing of XML to cibadmin
+ Known open bugs worth mentioning:
+ 1075, 1080, 1081, 1084, 1085, 1064, 1069, 756, 984
+ 1050, 1082, 1037, 1079 - Thu Sep 22 2005 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 2.0.2 - small bug fix only release
+ Fixed a bug in ping directive - it works again
+ Added a check to BasicSanityCheck to check ping and ping_group directives
+ fixed cl_status nodestatus to return 0 if a node has status "ping"
+ fixed a memory leak in the CRM's LRM interface code
+ fixed code which deterimines 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. - Wed Sep 14 2005 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 2.0.1 -
+ Communication Layer
+ netstring encoding format is changed to be more efficient
+ add compression capability for big messages
+ Add man pages for hb_standby/hb_takeover
+ The assert triggered by 2.0.0 has been fixed
+ CIB can now contain XML comments and/or be in DOS format
+ Includes implementation of the ISO8601 date format
+ New CLI tools for changing cluster preferences, node attributes
and node standby
+ Improved recovery and placement of group resources
+ Detection of failed nodes by the Policy Engine is fixed
+ New Policy Engine features
http://www.linux-ha.org/ClusterResourceManager/DTD1.0/Annotated :
sections 1.5.[8,9,10,12]
+ Constraints and instance attributes can now be active conditionally
+ Rules can now contain other rules
+ Date/Time based expressions are supported
+ Cloned resources can now optionally be notified before and after
any of its peers are stopped or started.
+ The cluster can re-evaluate the configuration automatically after
a defined interval of idleness
+ Removed a flow control message which was very annoying when operating
in a mixed 1.x/2.x environment
-- Known Bugs :-( --
- Bug 859 - FSA took too long to complete action - fully recovered from
- Bug 882 - IPC channel not connected during shutdown - harmless
- Bug 879 - Failed actions cause extra election - harmless
Each of these occurs about once or twice in 5000 test iterations
- This is probably > 10K failovers
- rsc_location constraints cannot have rules that contain other rules
(fixed in CVS after release) - Fri Jul 29 2005 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 2.0.0 - First stable release of the next generation of the Linux-HA project
+ Basic Characteristics described here:
http://linux-ha.org/FactSheetv2
+ Core infrastructure improvments:
+ Messaging (message acknowledging and flow control)
+ Logging (logging daemon)
+ Release 1.x style (2-node) clusters fully supported
+ Multi-node support (so far up to 16-node clusters tested)
See http://linux-ha.org/GettingStartedV2 for more information
+ New components:
+ Cluster Information Base (replicated resource configuration)
+ Cluster Resource Manager (supporting 1->N nodes)
+ Modular Policy Engine (controlling resource placement)
+ Local Resource Manager (policy free, not cluster aware)
+ Stonith Daemon (stand-alone fencing subsytem)
+ Support for OCF and LSB resource agents
+ Support for composite resource types (groups, clones)
+ Support for a rich set of resource location and ordering constraints
+ Conversion tool for existing haresources
+ Resources monitored by request
+ Resource "maintenance" mode
+ Several failback, failure and "No Quorum" behaviours to choose from
(global defaults and per action or resource)
+ Sample cluster state and configuration monitoring tools
Known issues in 2.0.0:
- Under some rare circumstances the cluster manager will time out
while stabilizing a new cluster state. This appears to be
otherwise harmless - the cluster is actually fine.
http://www.osdl.org/developer_bugzilla/show_bug.cgi?id=770
- Under some rare circumstances, a dev assert will be triggered
in unpack.c. This results in the pengine getting restarted.
This is annoying, but not a disaster.

+ many bug fixes - code looks very stable at this point
-- well tested at this point on 4 and 8 node clusters. - Thu Apr 7 2005 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 1.99.4 - Near-final beta of 2.0.0 release

+ new external STONITH model - fully supports scripting interface
+ tested through 12 node clusters successfully
+ No serious defects found in testing
+ Easier-to-understand locational constraints model
+ Many bug fixes of many kinds
+ Important bug fixes to OCF IPaddr resource agent
+ Resources are monitored only on request
+ See http://wiki.linux-ha.org/ClusterResourceManager/Setup
for basic ideas about getting started.
+ Release 1 style (2-node) clusters still fully supported
+ Release 2 style clusters support 1-N node clusters
(where N is probably something like 8-32) - Sun Mar 20 2005 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 1.99.3 - Near-final beta "technology preview" of 2.0.0 release

+ Version 1.99.2 - Near-final beta "technology preview" of 2.0.0 release
+ Many many many changes. Far too many to describe here.
+ See http://wiki.linux-ha.org/ClusterResourceManager/Setup
for certain basic ideas about getting started. - Mon Oct 11 2004 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)
+ Version 1.99.1 - *early* beta series - preparing for 2.0.0

+ All STABLE changes noted below have been ported to this branch
+ Included in this release is a beta of the next generation of Heartbeat
resource manager developed by Andrew Beekhof.
http://linuxha.trick.ca/NewHeartbeatDesign is a good place to learn
more about this effort. Please examine crm/README, crm/test/README
and crm/crm-1.0.dtd for example usage and configuration.
+ Also included is the L(ocal) R(esource) M(anager) developed by IBM China
which is an integral part of the NewHeartbeatDesign.
+ Known caveats:
- STONITH as a whole has seen a code cleanup and should be tested
carefully.
- The external STONITH plug-in has undergone major surgery and
probably doesn't work yet.
- the new CRM is not perfectly stable with 3 nodes yet.
+ PLEASE see http://osdl.org/developer_bugzilla/enter_bug.cgi?product=Linux-HA
and use it to report quirks and issues you find! - Sat Sep 18 2004 Alan Robertson <alanr@unix.sh> (see doc/AUTHORS file)

. Several shutdown bugs addressed
. fixed sendarp to make a pid file, so we can shut it down
when we shut everything else down in case it's still running.
. Lots of minor bug fixes to IPC code
. Lots of minor bug fixes to ipctest program
. made BasicSanityCheck more tolerant of delays

. Switched to compiling lex/yacc sources the automake way
. Lots of minor CTS fixes...
+ ldirectord bug fixes:
. When new real servers are added on initialisation or when
the configuration file is reread they are marked with status
of -1 (uninitialised) so they will be checked and inserted
into the virtual service as required
. All checks use the checkport if set, otherwise the port set for
the individual real server. This was the case for http and
connect checks, but others had variations on this theme.
. When the configuration file is reread because it changed
on disk and autoreload is set, check the real servers
immediately rather than waiting for checkinterval to expire
. Already running message sent to stderr instead of stdout
. Support alternate server in real-server specific URL
. Treat the same real server with different weights as a different
real server. Fixes bug reported by Philip Hayward whereby the same
real-server would always have the same weight, regardless of
