RHBA-2009:1645 - 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 two bugs are now available.

Description

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

This update addresses the following bugs:

  • the udev rules for device-mapper-multipath were causing device-mapper to occasionally create multipath devices without using the user specified uid, gid, or mode. They have been replaced with equivalent rules that do not cause this issue. (BZ#537761)

  • when LUNs were unmapped from LSI storage arrays, the multipath rdac path checker was not marking the paths as failed. This caused IO to the device to hang instead of fail. The rdac path checker now marks unmapped LUNs as failed. (BZ#538463)

Users are advised to upgrade to these updated device-mapper-multipath packages, which resolve these issues.

Solution

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