RHBA-2015:0540 - Bug Fix Advisory

Topic

Updated mdadm packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 7.

Description

The mdadm packages contain a utility for creating, managing, and monitoring
Linux multiple disk (MD) devices.

The mdadm packages have been upgraded to upstream version 3.3.2, which provides
a number of bug fixes and enhancements over the previous version. (BZ#1085533)

This update also fixes the following bugs:

• Previously, on a system installed on Intel Matrix Storage Manager (IMSM) RAID,

a spare disk could not be added to the container because the mdmon utility did
not have access to write metadata to the disk. With this update, mdmon can now
access the disk and the disk can be added correctly to the container.
(BZ#1072979)

• Previously, on a system running two Intel Matrix Storage Manager (IMSM) RAID

arrays, if the system was rebooted while running container reshape, the reshape
did not continue after the reboot and the second RAID5 array became read-only.
With this update, the reshape continues after the reboot and the second RAID5
array can be mounted correctly. (BZ#1074970)

• Previously, if a system running Intel Matrix Storage Manager (IMSM) RAID was

rebooted during a container reshape, the reshape would not continue
automatically after the reboot. With this update the reshape continues
automatically after the reboot as expected. (BZ#1108027)

• Previously, the mdadm package installed a duplicate udev rule file, which

could result in mdadm being run twice on some system events. This could result
in race conditions. With this update, the mdadm package no longer installs the
duplicate udev rule file, and udev events behave as expected. (BZ#1181620)

Users of mdadm are advised to upgrade to these updated packages, which fix these
bugs and add these enhancements.

Solution

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