RHBA-2019:2475 - Bug Fix Advisory

Topic

Updated rear packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

Relax-and-Recover is a recovery and system migration utility. The utility produces a bootable image and restores from backup using this image. It allows to restore to different hardware and can therefore be also used as a migration utility.

This update fixes the following bug:

In cases of a large number (hundreds or more) of multipath devices, creation of a rescue image previously took a long time (potentially several hours) because scanning of disk devices was repeated many times and collected unnecessary information. With this update, scanning has been improved in the following ways:

• Scanning uses caching to avoid querying the multipath devices multiple times.
• Scanning queries only device-mapper devices for device-mapper specific information.
• Scanning avoids collecting information about FibreChannel devices.

As a result, the creation of the rescue image with hundreds of multipath devices now proceeds faster. (BZ#1726142)

Users of rear are advised to upgrade to these updated packages, which fix this bug.
