The release cycle for Pacemaker 1.1.14 has begun! The source code for a
release candidate is available at:
This release candidate introduces some valuable new features:
* Resources will now start as soon as their state has been confirmed on
all nodes and all dependencies have been satisfied, rather than waiting
for the state of all resources to be confirmed. This allows for faster
startup of some services, and more even startup load.
* Fencing topology levels can now be applied to all nodes whose name
matches a configurable pattern, or that have a configurable node attribute.
* When a fencing topology level has multiple devices, reboots are now
automatically mapped to all-off-then-all-on, allowing much simplified
configuration of redundant power supplies.
* Guest nodes can now be included in groups, which simplifies the common
Pacemaker Remote use case of a grouping a storage device, filesystem and VM.
* Clone resources have a new clone-min metadata option, specifying that
a certain number of instances must be running before any dependent
resources can run. This is particularly useful for services behind a
virtual IP and haproxy, as is often done with OpenStack.
As usual, the release includes many bugfixes and minor enhancements. For
a more detailed list of changes, see the change log:
Everyone is encouraged to download, compile and test the new release. We
do many regression tests and simulations, but we can't cover all
possible use cases, so your feedback is important and appreciated.
(You may notice we're starting with rc2; rc1 was released, but had a
compilation issue in some cases.)
