Topic

Updated mdadm packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

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

This update fixes the following bugs:

  • Previously, if an IMSM RAID array was interrupted during a reshape operation, the mdadm utility in some cases became unresponsive, and it was impossible to stop the container. Additionally, the new container size was registered not after the reshape finished, but only once the array has been reassembled. With this update, container reshapes finish successfully, and updated container sizes are registered immediately. (BZ#1331331)
  • Previously, mdadm in some cases terminated unexpectedly with a segmentation fault when reshaping multiple IMSM volumes created from NVMe drives. With this update, multi-volume IMSM reshapes finish successfully. (BZ#1334956)
  • Previously, mdadm in some cases terminated unexpectedly with a segmentation fault if trying to assemble an array which included a device with a device name longer than 15 characters. With this update, mdadm assembles arrays correctly even when an array uses device names longer than 15 characters. (BZ#1347808)
  • Previously, when IMSM RAID arrays ran a reshape operation, a race condition allowed launching a second reshape on the same array, before the first operation had completed. With this update, the race condition has been fixed, and the second reshape operation can start only once the first operation has completed. (BZ#1348544)

Users of mdadm 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.
