RHEA-2009:1377 - Product Enhancement Advisory
Synopsis
device-mapper-multipath bug-fix and enhancement update
Type/Severity
Product Enhancement Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated device-mapper-multipath packages that fix several bugs and add
various enhancements are now available.
Description
The device-mapper-multipath packages provide tools to manage multipath
devices using the device-mapper multipath kernel module.
This update applies the following bug fixes:
- Occasionally multipathd was ignoring a device's hardware type when
configuring it after a path was added.
- Multiple documentation errors were fixed.
- Multipathd would occasionally hang or crash while shutting down.
- Multipath would always return a failure exit code when removing a device
with multipath -f/-F.
- Multipathd wouldn't free its resources when it failed to execute a callout.
- Multipathd would always return a success exit code for interactive
commands, even if the command failed or was invalid.
- The mpath_prio_alua pritority callout was failing on some setups because
a buffer was too small.
- Multipathd was holding mount points in the /etc directory busy, even
after they were unmounted.
- Multipath and multipathd were racing to create the mulitpath devices for
newly added block devices. This was causing device creation to take a long
time on some systems, and could even cause devices to have incorrect
configurations.
This update adds the following enhancements:
- Default configurations were added for the Compellent Storage Center and
the IBM DS3200, DS3300, DS4700, and DS5000.
- It is now possible to set the verbosity level for the multipath and
multipathd commands in /etc/multipath.conf.
- The TUR path checker retries on more transient errors, so that multipathd
will not fail a path due to a transient error.
- There is a new priority callout mpath_prio_intel to support the Intel
Modular Server.
- There is now a multipath.conf.5 man page that explains the
/etc/multipath.conf configuration file.
All users are advised to upgrade to these updated packages, which resolve
these issues and add these enhancements.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
