RHBA-2008:0188 - Bug Fix Advisory

Topic

Updated cman packages that fix several bugs are now available.

Description

The Cluster Manager (cman) utility provides user-level services for
managing a Red Hat cluster.

The updated cman packages fix the following bugs:

• ccsd consumes 90%+ of the CPU during startup when two clusters on the

same subnet with different endian architectures are used.

• Potentially, a panic is caused after a device_write on ppc64 architectures.
• qdisk ignores the interval set in cluster.conf to check the heuristics.

All cman users should upgrade to the updated packages, which resolve
these bugs.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
