RHBA-2012:0437 - Bug Fix Advisory

Topic

Updated device-mapper-multipath packages that fix one bug are now available for
Red Hat Enterprise Linux 5.

Description

The device-mapper-multipath packages provide tools to manage multipath devices
using the device-mapper multipath kernel module.

This update fixes the following bug:

• The multipathd daemon creates its private namespace which is supposed to keep

only the file systems that are necessary for multipathd to run. However,
multipathd did not check every file system in the namespace, and the namespace
thus could contain also non-essential file systems. As a consequence, devices
containing such file systems could not be removed from the system. With this
update, multipathd verifies all file systems in its private namespace and
removes every non-essential file system found. The devices containing the
non-essential file systems can now be removed as expected when the file systems
are unmounted. (BZ#806204)

All users of device-mapper-multipath are advised to upgrade to these updated
packages, which fix this bug.

Solution

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