RHBA-2018:0306 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat OpenStack Platform 11.0 (Ocata) 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.

This update includes several important bug fixes, including:

• The NetApp driver was incorrectly reporting 'provisioned_capacity_gb',\

resulting in the scheduler using incorrect data and the over provisioning
values being off.
With this update, the driver does not report the 'provisioned_capacity_gb'
data, which allows the Block Storage code to perform the calculations. As a
result, the Block Storage scheduler can now properly calculate the over
provisioning values for NetApp 7mode and cmode backends. (BZ#1498816)

• This update adds support for multiple Availability Zones within a

single Block Storage volume service by defining the Availability Zones
on each driver section. (BZ#1452704)
