RHBA-2011:0294 - 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 resolve an issue are now available for Red Hat Enterprise Linux 6.

Description

The device-mapper-multipath packages provide tools to manage multipath devices by giving the "dm-multipath" kernel module instructions on what to do, as well as by managing the creation and removal of partitions for Device-Mapper devices.

These updated device-mapper-multipath packages fix the following bug:

  • Multipathd caches the value of sysfs attribute lookups for the path devices that make up a multipath device. Previously, these weren't being removed when the path devices were removed. As well, in some cases the cache was not helpful and not used. This occasionally caused memory leaks when path devices were removed and restored. With this update, the unnecessary caching has been completely removed and the cached values are now removed when the corresponding path device is removed. Consequently, the occasional memory leaks no longer occur. (BZ#672151)

All device-mapper-multipath users are advised to upgrade to these updated packages, which resolve this issue.

Solution

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