RHBA-2015:1902 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo)
for RHEL 7.

Description

Red Hat Enterprise Linux OpenStack Platform provides the facilities for
building 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 addresses the following issues:

• Previously, if Dell iSCSI ports were in legacy mode rather than virtual port mode, initialize_connection would fail to return connection information. If initialize_connection was called more than once for the same connection, it would attempt to map the volumes again and fail. Instead, it should just return the existing connection information and not try to map the volumes again.

Moreover, the Dell REST API 2.2 and later changed the format of the payload filter. This update provides support for both formats.

Finally, consistency group support is only supported in Dell REST API 2.1 or later. Version 2.0 is not supported, so an error is now produced if this version is detected. (BZ#1265731)
