Fedora Update Notification

Name        : mdadm
Product     : Fedora 16
Version     : 3.2.2
Release     : 15.fc16
URL         : http://www.kernel.org/pub/linux/utils/raid/mdadm/
Summary     : The mdadm program controls Linux md devices (software RAID arrays)
Description :
The mdadm program is used to create, manage, and monitor Linux MD (software
RAID) devices.  As such, it provides similar functionality to the raidtools
package.  However, mdadm is a single program, and it can perform
almost all functions without a configuration file, though a configuration
file can be used to help with some common tasks.

Update Information:

This update fixes two bugs in the RAID handling code related to reshaping of arrays.

Migration from non-RAID to RAID5 could fail due to a memory leak in mdadm which could stop the migiration process. This could happen when large disks are used.

The system would fail to mount a RAID that was in progress of a reshape to another RAID level.

All users of mdadm RAIDs are encouraged to upgrade.
This update fixes a critical bug in the handling of raids using old version 0.9 metadata.

With prior versions of mdadm it was possible to grow an old 0.9 raid above supported limits, thereby ruining the raid. This would could happen if updating the drives used for the raid using modern drives larger than 2TB.

Users of 0.9 metadata are encouraged to update. Users of more recent metadata should unaffected by this bug.

Note 0.9 metadata has not been the default format for many years. You can check the version of your raids' metadata by running the command 'mdadm --detail /dev/mdX' with /dev/mdX being your raid device. Your metadata version is specified by the 'Version' line in the output.

In addition this update fixes a bug in the update scripts calling systemd where mdadm service wasn't stopped correctly prior to the update.
