RHEA-2019:1121 - Product Enhancement Advisory

Topic

A new release of Red Hat Hyperconverged Infrastructure (RHHI) for Virtualization that fixes several bugs and adds various enhancements is now available.

Description

Red Hat Hyperconverged Infrastructure (RHHI) for Virtualization integrates
Red Hat Virtualization and Red Hat Gluster Storage, allowing you to
consolidate deployment and management of compute and software-defined
storage resources.

This update fixes the following bugs:

• Previously, when the generated configuration file was edited by the

user editing values in the tabs of the UI during the 'Review' step of
deployment, the original contents of the generated configuration file were
not updated. This has now been corrected and the file is updated with new
values as expected. (BZ#1666714)

• Previously, when a deployment used virtual disk optimization (VDO),

options related to VDO devices were added to non-VDO disks in the
/etc/fstab file. This meant that disks failed to mount after a reboot. This
has been corrected so that devices are configured correctly and all disks
mount correctly after reboot. (BZ#1667209)

• VDO volumes are not supported on top of thin provisioned volumes because

VDO is itself a type of thin provisioning. However, parts of the Cockpit UI
implied that these features could be used together. The user interface has
now been updated so that thin provisioning is disabled when VDO volumes
are present. (BZ#1610699)

• Previously, the logical size of a VDO volume was 10 times the size of the

brick by default. This meant that using the default settings wasted storage
space. The default size of the brick and the default logical size of the
VDO volume are now the same. (BZ#1629542)

• Gluster volumes can now be expanded across more than three nodes on

Red Hat Hyperconverged Infrastructure for Virtualization. (BZ#1632144)

• By default, virtual disks created during deployment used the 'sparse'

allocation policy, which reduced performance for RHHI for Virtualization.
The default allocation policy is now 'preallocated' to improve performance.
(BZ#1641592)

• Previously, attempts to fetch brick profile statistics failed because of

a missing check for NFS access, even though the statistics were fetched
correctly. This meant that attempting to view the profile of a volume
failed with the following error message:
"Could not fetch brick profile stats"
This is now checked correctly, and works as expected. (BZ#1518164)

• When a single node deployment was created using the Cockpit UI, the UI

indicated that the volume created was a replicated volume type when the
volume was actually a distributed volume type. This has been corrected
and the UI now correctly shows a distributed volume for this deployment
type. (BZ#1641483)

This update also provides the following enhancements:

• Previously, when users deployed RHHI for Virtualization using the

Cockpit UI, gdeploy was used to deploy and configure the cluster.
Gdeploy is now replaced by gluster-ansible, and ansible roles are used for
deployment and configuration instead. (BZ#1679091, BZ#1676405)

• Expanding volumes across more than three nodes is now supported.

(BZ#1632144)

• Distributed volumes are now supported for single node deployments of

RHHI for Virtualization only, using gluster-ansible roles. (BZ#1653576)

• If RHHI for Virtualization deployment fails, you can now start the

deployment process from scratch by running the gluster_cleanup.yml
playbook. See documentation for details. (BZ#1674713)

• IPv6 support is now available as a Technology Preview on

RHHI for Virtualization 1.6. Support is provided for IPv6-only
environments, including gateways and DNS providers. Refer to
documentation for configuration details. (BZ#1624708)

To receive these bug fixes and enhancements, update to the latest versions
of Red Hat Virtualization 4.3 and Red Hat Gluster Storage 3.4.
