Topic

Updated rear packages that fix several bugs are now available for Red Hat Enterprise Linux 7.

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 bugs:

  • Previously, under certain circumstances, rescue images created by ReaR did not include shared libraries provided by the system. This occurred, for example, in situations when additional libraries of the same name were included in the images by using the COPY_AS_IS option, which happens especially when using the NetBackup utility for backups. Consequently, the images could not be used for restoring the system. The bug has been fixed by including both the additional library and the system library. As a result, NetBackup can now be successfully used as a backup mechanism with ReaR. (BZ#1663418)
  • When using NetBackup as a backup mechanism, verification of binaries included in the rescue system previously failed, because the NetBackup-specific library path was not specified. As a consequence, generation of a rescue image failed. With this update, it is possible to specify an additional library path, and redundant libraries are no longer included. As a result, the NetBackup mechanism now works as expected with ReaR. (BZ#1663419)
  • 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#1680486)

  • Several bugs in ReaR affecting complex network configurations previously occurred:
  • If teaming, or bonding with the SIMPLIFY_BONDING option, was used together with the Link Aggregation Control Protocol (LACP), the LACP configuration was not restored in the rescue system.
  • If a network interface was renamed from the standard name, such as ethX, to a custom name, ReaR did not restore the configuration of the interface in the rescue system.
  • When bonding was used, ReaR recorded an incorrect MAC address of the network interfaces in the bond because their MAC addresses were changed to the one of the first bond member.

As a consequence, in any of the described scenarios, the network did not function properly in the rescue system, making it impossible to restore backups accessed over the network without manual intervention. The bugs have been fixed, and it is now possible to recover network backups in the aforementioned network setups. (BZ#1664304, BZ#1663463, BZ#1663436)

WARNING: In case of teaming, this update might introduce another problem. If the team has multiple member interfaces, the team device might not be configured correctly in the rescue system. To work around this problem, preserve the previous behavior by adding the following line in the /etc/rear/local.conf file:

“SIMPLIFY_TEAMING=y”

For the newly added LACP support, temporarily remove all interfaces but one from the team during the rescue image creation process as a workaround. (BZ#1685166)

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

Solution

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