1.26.3. RHBA-2011:0379: device-mapper-multipath bug fix update

Updated device-mapper-multipath packages that resolve an issue are now available for Red Hat Enterprise Linux 5.

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:

* If a device's last path was deleted while the multipathd daemon was trying to reload the device map, or if a ghost path failed, multipathd did not always switch into the recovery mode. As a result, multipath devices could not recover I/O operations in setups that were supposed to temporarily queue I/O if all paths were down. This update resolves both of these issues; multipath now correctly recovers I/O operations as configured. (BZ#683447)

All users of device-mapper-multipath are advised to upgrade to these updated packages, which resolve this issue.
