7.142. mdadm
Updated mdadm packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The mdadm packages contain a utility for creating, managing, and monitoring Linux MD (multiple disk) devices.
Note
The mdadm packages have been upgraded to upstream version 3.2.5, which provides a number of bug fixes and enhancements over the previous version. (BZ#812358)
Bug Fixes
- BZ#824815
- While an Intel Matrix Storage Manager (IMSM) RAID volume was in the process of a reshape, an attempt to stop all arrays could cause an IMSM RAID array to be broken or corrupted. The underlying source code has been modified and mdadm works as expected in the described scenario.
- BZ#862565
- This update clarifies a number of mdadm license ambiguities.
- BZ#878810
- The IMSM optional ROM (OpROM) does not support RAID volumes across more than one controller. Previously, creating an IMSM RAID volume across more than one controller caused data loss. With this update, creating an IMSM RAID volume on multiple controllers is forbidden to prevent the data loss.
- BZ#880208
- Previously, it was possible to create a second RAID1 volume with the size equal to 0. As a consequence, when resyncing the first RAID1 volume was finished, the system became unresponsive. This update applies a patch to correct this error and it is no longer possible to create a second RAID1 volume with the size equal to 0.
- BZ#880225
- After turning off two disk drives of a RAID1 volume, using the "mdadm --detail" command caused mdadm to terminate unexpectedly with a segmentation fault. This update applies a patch that fixes this bug. Using the "mdadm --detail" command now returns valid information and mdadm no longer crashes in the described scenario.
- BZ#820643
- This update fixes the map file location in mdadm(8) man page.
Users of mdadm are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
