RHBA-2019:3251 - Bug Fix Advisory

Topic

Updated Red Hat Gluster Storage Wed Administration packages that fix several bugs are now available.

Description

Red Hat Gluster Storage Web Administration includes a fully automated setup
based on Ansible and provides deep metrics and insights into active Gluster
storage pools by using the Grafana platform. Red Hat Gluster Storage
Web Administration provides a dashboard view which allows an administrator
to get a view of overall gluster health in terms of hosts, volumes, bricks,
and other components of GlusterFS.

This update fixes the following bugs:

• The previously shipped version of the python2-pyasn1 package caused

IPA client installation to fail. This package is replaced with updates
to tendrl-notifier and tendrl-commons so that pysnmp is used instead
of python2-pyasn1, and installation works as expected. Before upgrading
to Red Hat Gluster Storage Web Administration 3.5, remove the
python2-pyasn1 and pysnmp packages (but not their dependencies) by
running the following commands:
# rpm -e --nodeps $(rpm -qa 'python2-pyasn1')
# rpm -e --nodeps $(rpm -qa 'pysnmp')
(BZ#1645428)

• Previously, tendrl did not set an owner for the

/var/lib/carbon/whisper/tendrl directory. When the owner of this
directory was not the 'carbon' user, carbon-cache could not create
whisper files in this location. Tendrl now ensures the directory is
owned by the 'carbon' user to ensure whisper files can be created.
(BZ#1647322)

• Previously, errors that occurred because tendrl-monitoring-integration

was not running were reported with generic error messages. More specific
error messages about tendrl-monitoring-integration status is now logged
in this situation. (BZ#1688630)

• Previously, Red Hat Gluster Storage Web Administration expected all

nodes to be online before any node could stop being managed by web
administration. It is now possible to remove a node from being managed
even when one or more nodes in the cluster are not online. (BZ#1645221)

• Red Hat Gluster Storage Web Administration previously received all

split brain related events and displayed these as errors in the user
interface, even when they were part of correctly operating heal processes.
Events are now filtered based on the client identifier to remove
unnecessary and erroneous errors from the user interface. (BZ#1666386)

• Previously, when all nodes in a cluster were offline, the web

administration interface did not report the correct number of nodes
offline. Node status is now correctly tracked and reported. (BZ#1687333)

• Previously, Ansible 2.8 compatibility did not work correctly.

Red Hat Storage Web Administration is now compatible with Ansible 2.8.
(BZ#1702412)

• The node-agent service is responsible for import and remove (stop

managing node) operations. These operations timed out with a generic log
message when the node-agent service was not running. This issue is now
logged more clearly when it occurs. (BZ#1686888)

All users of Red Hat Gluster Storage Web Administration are advised to
upgrade to these updated packages, which fix these bugs.
