RHBA-2018:3785 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat OpenStack Platform 12.0 (Pike) 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:

• Previously, the Cinder RBD driver consumed excessive CPU resources when updating usage statistics for the Ceph RBD pool, resulting in cinder volume operations timing out.

With this update, the RBD driver no longer consumes excessive CPU resources and cinder operations no longer due to timeouts. (BZ#1593316)

• Previously, OS-Brick prevented attachments on VNX FC when VNX returned a `none` value for the `initiator_target_map` key in FC target data.

With this update, the `initiator_target_map` key is removed from the target data dict when the value is `none`, and attachments on VNX FC that do not have an initiator target map succeed. (BZ#1613892)

• With this update, the force_detach action of NetApp ONTAP FC/iSCSI drivers succeeds. This action terminates all connections between the specified volume and any host that is mapped to the volume. (BZ#1622538)
• Previously, attempts to delete a consistency group snapshot caused the SolidFire driver to crash.

With this update, attempts to delete a consistency group snapshot no longer cause the SolidFire driver to crash. (BZ#1629051)

• Previously, Cinder updated quotas incorrectly when deleting a temporary volume and operations that required that Cinder use a temporary volume resulted in corrupted quotas.

With this update, Cinder handles quote correctly when deleting temporary volumes. (BZ#1597737)

• Previously,creating volumes from an image failed when the SolidFire driver image cache was enabled.

With this update, the SolidFire driver configuration has been updated so that the driver image cache is disabled by default. Cinder includes a driver-independent image cache. (BZ#1613536)

• Previously, attempts to force detach a volume caused the SolidFire driver to crash.

With this update, attempts to force detach a volume no longer cause the SolidFire driver to crash. (BZ#1638408)

• The Block Storage service (cinder) uses two volume cache limit settings. Previously, when only one cache limit was configured, adding a new entry to the cache caused an existing entry to be ejected from the cache. Only a single entry would be cached, regardless of the configured cache limit.

With this update, the Block Storage service handles volume cache limits correctly. (BZ#1642155)
