RHBA-2012:0960 - Bug Fix Advisory

Topic

An updated system-config-lvm package that fixes multiple bugs is now available
for Red Hat Enterprise Linux 6.

Description

The system-config-lvm package contains a utility for configuring logical volumes
using a graphical user interface.

This update fixes the following bugs:

• The system-config-lvm utility incorrectly displayed all LVM devices in the

"Unitialized Entities" group. This could confuse users who could try to
re-initialize logical volumes unnecessarily. This update modifies
system-config-lvm to show LVM devices as "Unitialized Entities" only if the
logical volumes really are uninitialized. (BZ#791153)

• The system-config-lvm utility uses fdisk as a back end for partition

operations. The fdisk utility does not support the Extensible Firmware Interface
(EFI) GUID Partition Table (GPT), so an attempt to initialize a physical
partition on EFI GPT fails. However, system-config-lvm previously did not handle
this situation correctly and the operation failed without any error message.
This update modifies the underlying code so that system-config-lvm now provides
a valid error message in this situation. (BZ#708029)

• The system-config-lvm utility did not properly handle physical partitions with

names in the form of "*p[0-9]", for example, "loop0p0". Therefore,
system-config-lvm terminated unexpectedly when attempting to initialize such a
partition. This update modifies the underlying code so that system-config-lvm no
longer crashes in this scenario. However, system-config-lvm still does not
handle such partition names and such partitions cannot be initialized.
(BZ#726830)

• The system-config-lvm utility uses the dmsetup tool for obtaining information

from Device Mapper Multipath. Output of dmsetup was designed to be parsed by
scripts, however, with an update of device-mapper-multipath to version 1.02.74,
this output was changed. As a consequence, system-config-lvm terminated
unexpectedly with a traceback when used with Device-Mapper Multipath available
on the system. This update modifies system-config-lvm to use a user-specified
output which does not change across different versions. The system-config-lvm
utility now works as expected. (BZ#815921)

All users of system-config-lvm are advised to upgrade to this updated package,
which fixes these bugs.
