RHBA-2012:0437 - device-mapper-multipath bug fix update

Synopsis

device-mapper-multipath bug fix update

Type/Severity

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.
