RHBA-2019:2627 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat OpenStack Platform 13.0 (Queens) for RHEL 7.

Description

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

• OpenStack Block Storage service

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The back-end
physical storage can consist of local disks, Fiber Channel, iSCSI, and/or
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programmatic management is available through the Block Storage service's
API.

Changes to the openstack-cinder component:

• This update expands the Block Storage service multi attach feature to the Ceph RBD driver. (BZ#1700882)
• Previously, the Cinder HPE 3PAR driver did not correctly maintain the connection status of a volume when multiple instances were attached to the same volume. This caused a volume status to remain in the detaching state when a second instance was detached from a volume with multiple connections.

With this update, the multi-attach behavior of the 3PAR driver functions correctly. (BZ#1725012)

• Previously, in certain cases, when the Block Storage service failed to create a cloned volume from the existing image cache volume, it retrieved an image from the Image service, but did not recreate the image cache.

With this update, the Block Storage services recreates the image cache after failing to create a cloned volume. (BZ#1717727)
