RHBA-2010:0728 - Bug Fix Advisory

Topic

Updated device-mapper-multipath packages that fix a bug are now available for
Red Hat Enterprise Linux 5.

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 packages provide a fix for the following bug:

• Due to a race condition between udev and Device-Mapper, kpartx may have

attempted to create partitions on a multipath device before it was completely
initialized, causing no Device-Mapper partitions to be created. With this
update, udev now waits for the multipath device to be completely initialized
before attempting to create partitions on it. (BZ#634903)

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

Solution

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

This update is available via Red Hat Network. Details on how to use the Red
