RHBA-2017:3233 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat OpenStack Platform 10.0 (Newton) 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:

• The NetApp driver was incorrectly reporting the `provisioned_capacity_gb` value. Consequently, the scheduler's over provisioning calculations were using incorrect data and provided wrong results. The problems has been fixed by disabling the driver from reporting `provisioned_capacity_gb` data and using Cinder core code to do the calculation instead. As a result, the Cinder Scheduler can now properly calculate over provisioning values for the NetApp 7mode and cmode backends.
• The function `delete_volume` of the DELL SC driver was unaware of migration and it did not check that the delete command was sent to the right backend. Consequently, the driver deleted a wrong volume. The problem has been fixed. The driver checks the volume before it deletes it from the configured backend. As a result, the migration completes successfully and the correct volume is deleted.
