I am proud to announce the first independent release of Pacemaker.
Most of you will know Pacemaker as the Heartbeat CRM however, in
addition to being a separate project, it now also supports the OpenAIS
cluster stack!
Packages for Pacemaker and it's immediate dependancies can be
downloaded from the usual location:
http://software.opensuse.org/download/server:/ha-clustering
and the source can be obtained from:
http://hg.clusterlabs.org/pacemaker/stable-0.6/archive/Pacemaker-0.6.0.tar.bz2
For a breakdown of the available packages and what parts are optional,
please refer to
http://clusterlabs.org/mw/Install#Package_List
This release also marks the start of our first (feature frozen) stable
series for which we will provide bug-fix-only updates until at least
2009.
More information regarding Pacemaker (including the name, choice of
version number and how to install) is available at:
http://clusterlabs.org/mw/FAQ
regards,
Andrew
Begin lazy paste from the changelog...
* Update source tarball to revision: c94b92d550cf
* Statistics:
Changesets: 347
Diff^: 2272 files changed, 132508
insertions(+), 305991 deletions(-)
^ The deceptively large numbers here are due to the amount of
non-CRM code that was removed and the new internal project layout
* Test hardware:
+ 6-node vmware cluster (sles10-sp1/256Mb/vmware stonith) on a
single host (opensuse10.3/2Gb/2.66Ghz Quad Core2)
+ 7-node EMC Centera cluster (sles10/512Mb/2Ghz Xeon/ssh stonith)
* Notes: Heartbeat Stack
+ All testing was performed with STONITH enabled
+ The CRM was enabled using the "crm respawn" directive
+ Testing
2-nodes ::= 1000 CTS iterations (passed)
4-nodes ::= 1000 CTS iterations (passed)
6-nodes ::= 2000 CTS iterations (passed)
+ Total estimated cluster transitions: 18000
* Notes: OpenAIS Stack
+ This release contains a preview of support for the OpenAIS
cluster stack
+ The current release of the OpenAIS project is missing two
important
patches that we require. OpenAIS packages containing these
patches are
available for most major distributions at:
http://download.opensuse.org/repositories/server:/ha-clustering
+ The OpenAIS stack is not currently recommended for use in
clusters that
have shared data as STONITH support is not yet implimented
+ pingd is not yet available for use with the OpenAIS stack
+ 3 significant OpenAIS issues were found during testing of 4 and
6 node
clusters. We are activly working together with the OpenAIS
project to
get these resolved.
+ Testing
2-nodes ::= 1000 CTS iterations (passed)
4-nodes ::= 1000 CTS iterations (sporadic problems - see
pending bugs)
6-nodes ::= 1000 CTS iterations (significant problems - see
pending bugs)
+ Total estimated cluster transitions: 12000
* Pending bugs encountered during testing:
+ OpenAIS #1736 - Openais membership took 20s to stabilize
+ Heartbeat #1750 - ipc_bufpool_update: magic number in head does
not match
+ OpenAIS #1793 - Assertion failure in memb_state_gather_enter()
+ OpenAIS #1796 - Cluster message corruption
