RHEA-2005:596 - Product Enhancement Advisory

Topic

Updated device-mapper packages that include various enhancements are now
available.

Description

The device-mapper packages provide a library required by logical volume
management utilities such as LVM2 and dmraid.

These packages include the following enhancements:

• In addition to its column-based output, 'dmsetup -c info',

colon-separated output is now available, 'dmsetup -c --noheadings info'.
To replicate multipath devmap_name functionality add '-o name'.

• Support for selinux. An error in the upstream package meant that the

configuration option RHEL4 uses to enable selinux support had no
effect. Consequently device file contexts were not set correctly.

• Two new dmsetup command-line options. 'dmsetup ls --target

<target_type> --exec <command>' executes <command> for each
device that has at least one target of <target_type>.

• When a program using libdevmapper exits, dm_lib_exit() gets called

automatically. It is not necessary to call it explicitly any more.
Existing calls can be left as they are: it is safe to call it twice in
succession.

All users of device-mapper should upgrade to these updated packages, which
include these enhancements.
