RHBA-2014:1216 - Bug Fix Advisory

Topic

Updated clustermon packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

Description

The clustermon packages are used for remote cluster management. The modclusterd
service provides an abstraction of cluster status used by conga and by the
Simple Network Management (SNMP) and Common Information Model (CIM) modules of
clustermon.

This update fixes the following bug:

• The modcluter module is a ricci module shipped with the clustermon packages.

Previously, modcluster mishandled requests with size in bytes divisible by 4096,
which is the size of the read buffer in bytes. Consequently, modcluster
incorrectly evaluated such requests as errors. This bug has been fixed and
modcluster now processes all requests as expected. See also RHBA-2014:17045 for
the information about the remaining ricci modules shipped with the ricci
packages. (BZ#1076714)

Users of clustermon are advised to upgrade to these updated packages, which fix
this bug.
