[ClusterLabs] Pacemaker 1.1.15 - Release Candidate 3

[Ken Gaillot]

The third release candidate for Pacemaker version 1.1.15 is now
available at:

https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-1.1.15-rc3

Perhaps the most visible change since 1.1.15-rc2 is that many log
messages have been made more user-friendly. Partly this is due to taking
advantage of the "extended information logging" feature of libqb 0.17.2
and greater (if installed on the build machine); the same message may be
logged to the system log without developer-oriented details, and to the
pacemaker detail log with the extra detail.

This release candidate includes multiple bugfixes since 1.1.15-rc2, most
importantly:

* In 1.1.14, the controld resource agent was modified to return a
monitor error when DLM is in the "wait fencing" state. This turned out
to be too aggressive, resulting in fencing the monitored node
unnecessarily if a slow fencing operation against another node was in
progress. The agent now does additional checking to determine whether to
return an error or not.

* A bug introduced in 1.1.14, resulting in the have-watchdog property
always being set to true, has been fixed. The cluster now properly
checks for a running sbd process.

* A regression introduced in 1.1.15-rc1 has been fixed. When a node ID
is reused, attrd would have problems setting attributes for the new node.

Everyone is encouraged to download, compile and test the new release.
Your feedback is important and appreciated. I am aiming for one more
release candidate, with the final release in mid- to late June.
