RHBA-2014:0410 - 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:

  • Previously, if the user created duplicate aliases, or aliases that matched the user_friendly names, those devices switched their paths, and thus caused multipath device path corruption. The underlying code has been fixed, and the multipath utility now refuses to reload a device with an existing duplicate alias. In addition, multipath now issues a warning message on potentially conflicting aliases. As a result, multipath no longer corrupts data if users name two devices identically. (BZ#1065229)

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.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
