RHBA-2005:734 - Bug Fix Advisory

Topic

An updated cman-kernel package that fixes various bugs is now available.

Description

The cman-kernel package contains modules that allow the cluster manager
(cman) to communicate with the kernel.

These updated cman-kernel packages are in sync with the latest kernel
(2.6.9-22.EL). The modules in earlier cman-kernel packages fail to load
because they do not match the running kernel. It is possible to force the
loading of the modules; however, this update alleviates the need to do so.

In addition, the following bugs have been discovered and addressed since
the previous release:

• A bug was found which would cause cman-kernel to output a cryptic message

and, in rare cases, prevent a reboot of the machine when its interfaces
were down.

• A bug was found which could cause the cman join to lock up after fencing.
• A potential deadlock was removed.
• A bug was found which allowed new clients to mount a GFS file system

before fencing had completed.

• A bug was found which ignored future joins/leaves after a large number of

joins/leaves were processed.

All users of cman-kernel should upgrade to this updated package, which
resolves these issues.

Solution

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
