RHBA-2011:0384 - 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 for Red Hat Enterprise Linux 6.
Description
The device-mapper-multipath packages provide tools to manage multipath devices by giving the "dm-multipath" kernel module instructions on what to do, as well as by managing the creation and removal of partitions for Device-Mapper devices.
These updated device-mapper-multipath packages fix the following bug:
- Prior to this update, multipathd did not always remove a path's sysfs device from cache when the path was removed. Also, multipathd searched the cache and created sysfs devices without the 'vecs' lock held. As a result, paths would occasionally have invalid sysfs devices, causing multipathd crashes and other errors. With this update, multipathd always removes the sysfs device from cache when deleting the path, and it only accesses the cache with the 'vecs' lock held. (BZ#684684)
All users of device-mapper-multipath are advised to upgrade to these updated packages, which resolve this issue.
Solution
