RHBA-2014:1695 - Bug Fix Advisory

Topic

Updated openstack-cinder packages that fix multiple
bugs are now available for Red Hat Enterprise Linux OpenStack Platform 4.0.

Description

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The backend
physical storage can consist of local disks, or Fiber Channel, iSCSI, and
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programatic management is available via Block Storage’s API.

This update re-bases the Block Storage service to version 2013.2.4. This, in
turn applies several bug fixes, including:

• Prior to this update, certain Qpid exceptions were not properly handled by the

Qpid driver. In the event of such exceptions, the Qpid connection would fail and
stop processing subsequent messages. With this update, all possible exceptions
are handled to ensure the Qpid driver does not enter an unrecoverable failure
loop. Consequently, Orchestration (heat) will continue to process Qpid messages,
even after major exceptions occur.

• The Block Storage service now ensures that the I/O for each SCSI device gets

flushed before a FibreChannel device is removed. In addition, whenever a LUN
associated with a multipath device is removed, the device is flushed first.
These fixes help prevent kernel I/O errors arising from stale volume entries.

All users of openstack-cinder are advised to apply this update. After installing
the updated packages, running Block Storage services will be restarted
automatically.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
