Fixed In Version:	libqb-0.17.1-1.el6	Doc Type:	Rebase: Bug Fixes and Enhancements
Doc Text:	The libqb packages have been upgraded to upstream version 0.17.1, which provides a number of bug fixes and enhancements over the previous version. One of the notable changes gives components consuming inter-process communication (IPC) API of libqb more control over IPC buffer sizes. The ability to utilize larger buffer sizes in a consistent way between the IPC client and server allows pacemaker to scale much further in the number of resources the cluster can manage.

Description David Vossel 2014-06-16 22:08:17 UTC

Description of problem:

We need to rebase to the Libqb v0.17.0 upstream release.

Libqb v0.17.0 introduced the ability for ipc servers to dictate the size of the ipc bufferes. Pacemaker (which uses libqb) needs the ability to enforce buffer sizes on ipc clients to handle the large CIB files generated when large amounts of remote-nodes and resources are in use.

Comment 2 David Vossel 2015-01-16 18:36:13 UTC

https://github.com/ClusterLabs/libqb/releases/tag/v0.17.1

upstream version libqb 0.17.1 resolves this.

Comment 4 David Vossel 2015-02-23 23:12:21 UTC

The unit test should only involve sanity testing that libqb works as expected in a pacemaker environment.

Pacemaker has to be updated before the buffer enhancements will do anything. Those changes are being tracked here, https://bugzilla.redhat.com/show_bug.cgi?id=1195500
