RHBA-2009:0432 - device-mapper-multipath bug fix update
Synopsis
device-mapper-multipath bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated device-mapper-multipath packages that resolve an issue are now available.
Description
The device-mapper multipath packages provide tools to manage multipath devices by issuing instructions to the device-mapper multipath kernel module, and by managing the creation and removal of partitions for device-mapper devices.
These updated device-mapper-multipath packages fix the following bug:
-
there was a race condition in the shutdown code for multipathd wherein a lock could be destroyed before all threads were finished using it. This could cause the machine to become unresponsive on multipathd shutdown. The multipathd daemon now waits for all threads to finish using the lock before destroying it, thus removing the race and resolving the issue.
-
when adding a new multipath-capable block device, a race condition existed between the multipathd daemon and udev to multipath the new device. If udev--through multipath--updated the multipath devices first, then the multipathd daemon would not use the device-specific configurations for the device when it started monitoring the path. With this update, multipathd now correctly configures the device, even when udev notices it first, thus resolving the issue.
All users of device-mapper-multipath are advised to upgrade to these updated packages, which resolve this issue.
