-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2011-16299 2011-11-23 22:56:12 --------------------------------------------------------------------------------
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. -------------------------------------------------------------------------------- ChangeLog: * Mon Nov 21 2011 Jes Sorensen <[email protected]> - 3.2.2-15 - Backport upstream fix for memory leak that can prevent migration to RAID5 from completing. - Backport upstream fix preventing mounting a device while it is in process of reshaping - Resolves: bz755005 bz755009 * Wed Nov 9 2011 Jes Sorensen <[email protected]> - 3.2.2-14 - Backport upstream fixes to prevent growing v0.90 metadata raid out of supported size. - Add missing 'disable' argument to systemctl in preun script - Resolves: bz735306 (Fedora 15) bz748731 (Fedora 16) bz748732 (rawhide), Resolves: bz751716 -------------------------------------------------------------------------------- References: [ 1 ] Bug #755005 - Migration to RAID5 is sometimes not possible (memory leak) https://bugzilla.redhat.com/show_bug.cgi?id=755005 [ 2 ] Bug #755009 - During reshape mounting device is impossible https://bugzilla.redhat.com/show_bug.cgi?id=755009 [ 3 ] Bug #748731 - mdadm may grow an array beyond supported limits https://bugzilla.redhat.com/show_bug.cgi?id=748731 [ 4 ] Bug #751716 - Typo in %preun script https://bugzilla.redhat.com/show_bug.cgi?id=751716 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
