RHBA-2015:2075 - Bug Fix Advisory

Topic

Updated OpenStack Compute packages that resolve one issue are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 6.

Description

Red Hat Enterprise Linux OpenStack Platform provides the facilities for building a private or public infrastructure-as-a-service (IaaS) cloud running on commonly available physical hardware. This advisory includes packages for:

• OpenStack Compute service

OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects.

This update addresses the following issue:

• Nova can often overload multipathd with multiple calls when attaching fibre channel volumes to instances, and later calls can miss recently attached LUNs as multipathd struggles to create multipath devices in time. As a consequence, LUNs are not found by Nova and volume attachment fails. Upstream the fix is to avoid querying multipathd at all within the new os-brick library. As this is not possible downstream, the updated package retries queries where a LUN is not found initially. As a result, nova now retries multipathd queries allowing time for multipath devices to be created and for volume attachment to complete successfully. (BZ#1270125)
