RHBA-2018:1602 - 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:

• With debug logging enabled, Cinder logged the RabbitMQ password into log files. This update masks the password in the log files. (BZ#1547600)
• The volume service reports statistics from the storage backend. However, race conditions caused the volume service scheduler to use out of date statistics and create more volumes than it should. This fix removes the race conditions. The scheduler now uses up to date statistics and creates volumes closer to the configured limits. (BZ#1553738)
• This update improves the debug log messages the scheduler outputs. This provides more information on scheduler decision making and the data used in the decision making process. (BZ#1543823)
• This update provides support for volume migration between different availability zones. (BZ#1554784)
