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.
This update includes the following fixes and enhancements:
- This update adds support for multiple Availability Zones within a single Block Storage (cinder) volume service; this is done by defining the AZ in each driver section. (BZ#1488390)
- A specific Storage Center firmware is incorrectly returning a `WWN` value as `wWN`. Consequently, the attach operation would fail as the cinder driver could not find the WWN. This update adds case-insensitive matching of WWN values when searching data returned by the storage backend. As a result, attach operations now work as expected. (BZ#1523150)
- Previously, OS-Brick could not properly attach an encrypted volume if it did not know it was encrypted; in addition, the `create volume from image` process flow in cinder did not indicate the encryption status. Consequently, since the attach process flow was incorrect, it resulted in remaining symlinks in the detach process that would affect future attachments. With this update, cinder now marks encrypted volumes during the `create volume from image` process. As a result, you can now create multiple consecutive encrypted volumes from an image. (BZ#1523676)
- Previously, the Dell EMC PS driver took too long to process backend stats. This resulted in timeouts for cinder operations.
This update optimizes the backend polling of the Dell EMC PS driver. As a result, the cinder-volume performance has improved. (BZ#1506311)
- Prior to this update, a bug was present in the Nimble cinder volume driver. Consequently, volume operations using the Nimble cinder driver would fail when creating volumes with non-ascii Unicode characters in the volume name or decryption. This update to the Nimble cinder driver addresses the issue, and users can now create volumes with any name or description. (BZ#1521217)
- Previously, certain method calls for backup/restore operations would block the eventlet's thread switching. Consequently, operations were slower and connection errors were observed in the database and RabbitMQ logs. With this update, proxy blocking method calls were changed into native threads to prevent blocking. As a result, restore/backup operations are faster and the connection issues are resolved. (BZ#1504661)
- This update adds support for remote snapshot attachment for backups. This was added because some backends can attach remote snapshots, but have inefficient `create volume from snapshot` operations, so the inability to remotely attach a snapshot prevents efficient snapshot or in-use volume backups when scaling out the backup service. As a result, the backup service can efficiently scale out without having to be concerned about whether it is co-located with the volume service on the same node. (BZ#1519867)
- Prior to this update, the logging library was not properly monkey patched by eventlet. Consequently, all log entries would have the request ID of the latest request that was received in the backup service. With this update, eventlet correctly monkey patches the logging library, and log entries will have the expected request ID. (BZ#1538089)
