RHBA-2011:0173 - 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:

  • When all paths of a pathgroup with set group_by_prio were restored after a failure, multipathd could place some paths into a wrong pathgroup. This issue occurred, because the daemon checked if pathgroups needed reconfiguration only if a path priority changed. When the original paths were restored, they could have been assigned the same priority as before the failure. In such case the paths were incorrectly left in a wrong pathgroup. With this update, when checking if it needs to recalculate the pathgroups, the multipathd daemon refreshes and checks all priorities once a new path becomes available and places recovered paths into the correct pathgroup. (BZ#658937)

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