I am pleased to announce the latest maintenance release of Corosync
3.1.1 available immediately from GitHub release section at
https://github.com/corosync/corosync/releases or our website at
http://build.clusterlabs.org/corosync/releases/.
This release contains important bug fixes and also a few new features:
- Added a new API to get extended node/link information which is now
used by corosync-cfgtool (especially when the new -n parameter is used).
See corosync-cfgtool(8) for more information.
This makes me wonder: "Good old ping" had always been able to display the
delay between request and response.
As the message delay (token round-trip time)is also critical in corosync, I
wonder why the current delay cannot be displayed by corosync-cfgtool for
example. My expectation is that the delay will go up significantly when load
There is latency stored in stats map (corosync-cmapctl -m stats) so I
can image to display that in the corosync-cfgtool output.
increases, and maybe manual "re-tuning" could be done before the infamous
"retransmit timeout" kicks in.
Yup (actually ideally automatic but that's long term task).

- The API for cfg tracking was fixed so it now working again. This API
was removed during the Corosync 2 development cycle and it means that
shutdown tracking (using cfg_try_shutdown()) had stopped working.
Now it is back, so an application may register to receive a callback
when corosync is stopped cleanly (using corosync-cfgtool -H) and can
also prohibit corosync from stopping.
There is a new --force option (which is now the default in the systemd
unit file/init script) which will always cause Corosync to shut down.
This feature is going to be used by an as-yet unreleased Pacemaker
version (currently in the master branch) to veto corosync shutdown.
