instack-undercloud

BZ#1212158

This updates provides OpenStack notifications. Previously there were external consumers of OpenStack notifications that could not interface with director-deployed cloud because notifications were not enabled. Now director enables notifications for external consumers.

BZ#1296295

Running "openstack undercloud install" attempted to delete and recreate the Undercloud's neutron subnet even if the subnet required no changes. If an Overcloud was already deployed, the subnet delete attempt failed since the subnet contained allocated ports. This caused the "openstack undercloud install" command to fail. This fix changes this behavior to only attempt to delete and recreate the subnet if the  "openstack undercloud install" command has a configuration change to apply to the subnet. If an Overcloud is already deployed, the same error message still occurs since the director cannot delete the subnet. This is expected behavior though since we do not recommend change the subnet's configuration with an Overcloud already deployed. However, in cases with  no subnet configuration changes, the "openstack undercloud install" command no longer fails with this error message.

The Puppet manifest that installs the Undercloud referred to the wrong resource name to create the keystone domain for Heat. The undercloud install failed with an error such as:

puppet apply exited with exit code 1

This fix updates the Puppet manifest was changed to use the correct name of the resource. The Undercloud installation now finishes without an error.

BZ#1315546

When LANG was set to ja_JP.UTF-8, the output of the date command in "dib-run-parts" contained Japanese characters, which caused a unicode error in "_run_live_command()". The Undercloud installation failed with the following error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 18: ordinal not in range(128)
Command 'instack-install-undercloud' returned non-zero exit status 1

This fix decodes strings using the utf-8 character encoding during the Undercloud installation. Now the Undercloud installation completes successfully when LANG is set to ja_JP.UTF-8.

BZ#1312889

This update removes the Tuskar API service from Red Hat OpenStack Platform director 8. Tuskar was installed and configured on the Undercloud, including an endpoint existing in the Keystone service catalog. The RPM is no longer installed, the service is not configured, and the endpoint is not created in the service catalog.

openstack-ironic-inspector

BZ#1282580

The director includes new functionality to allow automatic profile matching. Users can specify automatic matching between nodes and deployment roles based on data available from the introspection step. Users now use ironic-inspector introspection rules and new python-tripleoclient commands to assign profiles to nodes.

BZ#1270117

Previously, periodic iptables calls made by Ironic Inspector did not contain the -w option, which instructs iptables to wait for the xtables lock. As a consequence, periodic iptables updates occasionally failed. This update adds the -w option to the iptables calls, which prevents the periodic iptables updates from failing.

BZ#1283650

Log processing in the introspection ramdisk did not take into account non-Latin characters in logs. Consequently, the "logs" collector failed during introspection. With this update, log processing has been fixed to properly handle any encoding.

BZ#1314642

The director uses a new ramdisk for inspection and deployment. This ramdisk included a new algorithm to pick the default root device for users not using root device hints. However, possible root device changes occurred on redployment, leading to failures. This fix reverts the ramdisk device logic to be the same as OpenStack Platform director 7. Note that this does not mean that the default root device is the same, as device names are not reliable. Also this behavior will change again in a future releases. Make sure to use root device hints if you nodes use multiple hard drives.

openstack-tripleo-heat-templates

BZ#1295830

Pacemaker used a 100s timeout for service resources. However, a systemd timeout requires an additional timeout period after the initial timeout to accommodate for a SIGTERM and then a SIGKILL. This fix increases the Pacemaker timeout to 200s to accommodate two full systemd timeout periods. Now the timeout period is enough for systemd to perform a SIGTERM and then a SIGKILL.

BZ#1311005

The notify=true parameter was previously missing from the RabbitMQ Pacemaker resource. Consequently, RabbitMQ instances were unable to rejoin the RabbitMQ cluster. This update adds support for notify=true to the pacemaker resource agent for RabbitMQ, and adds notify=true to OpenStack director. As a result, RabbitMQ instances are now able to rejoin the RabbitMQ cluster.

BZ#1283632

The 'ceilometer' user lacked a role needed for some functionality, which causes some Ceilometer meters to function incorrectly. This fix adds the necessary role to the 'ceilometer' user. Now all ceilometer meters work correctly.

BZ#1299227

Prior to this update, the swift_device and swift_proxy_memcache URIs used for the swift ringbuilder and the swift proxy memcache server respectively were not properly formatted for IPv6 addresses, lacking the expected '[]' delimiting the IPv6 address. As a consequence, when deploying with IPv6 enabled for the overcloud, the deploy failed with "Error: Parameter name failed on Ring_object_device ...". Now, when IPv6 is enabled, the IP addresses used as part of the swift_device and swift_proxy_memcache URIs are correctly delimited with '[]'. As a result, deploying with IPv6 no longer fails on incorrect formatting for swift_device or swift_proxy_memcache.

BZ#1238807

This enhancement enables the distribution of per-node hieradata, matching the nodes from their UUID (as reported by 'dmidecode').
This allows you to scale CephStorage across nodes equipped with a different number/type of disks.
As a result, CephStorage nodes can now be configured with non-homogeneous disk topologies. This is done by provisioning a different configuration hash for the ceph::profile::params::osds parameter.

BZ#1242396

Previously, the os-collect-config utility only printed Puppet logs after Puppet had finished running. As a consequence, Puppet logs were not available for Puppet runs that were in progress. With this update, logs for Puppet runs are available even when a Puppet run is in progress. They can be found in the /var/run/heat-config/deployed/ directory.

BZ#1266104

This update adds neutron QoS (Quality of Service) extensions to provide better control over tenant networking qualities and limits. Overclouds are now deployed with Neutron QoS extension enabled.

BZ#1320454

Stricter validation in Red Hat OpenStack Platform 8's Orchestration service (heat) caused the Overcloud stack update to fail from an upgraded Undercloud with the following error:

ERROR heat.engine.resource ResourceFailure: resources.Compute: "u'1:1000'" is not a list. 

This fix which properly formats the NeutronVniRanges parameter to include the required '[]' has been backported to the OpenStack Platform 7 openstack-tripleo-heat-templates package and should be available as of openstack-tripleo-heat-templates-kilo-0.8.14-5.el7ost.noarch. Now stack updates of the Overcloud stack will not fail with the error when using an upgraded Undercloud to manage an existing Overcloud while using the version 7 templates (which are located at /usr/share/openstack-tripleo-heat-templates/kilo).

The domain name for overcloud nodes defaulted to 'localdomain'. For example: 'overcloud-compute-0.localdomain'. This enhancement provides a parameter (CloudDomain) to customize the domain name. Create an environment file with the CloudDomain parameter included in the 'parameter_defaults" section. If no domain name is defined, the Heat templates default to 'localdomain'.

BZ#1308422

Previously, '/v2.0' was missing from the end of the URL specified in the admin_auth_url setting in the [neutron] section of /etc/nova/nova.conf. This would prevent Nova from being able to boot instances because it could not connect to the Keystone catalog to query for the Neutron service endpoint to create and bind the port for instances. Now, '/v2.0' is correctly added to the end of the URL specified in the admin_auth_url setting, allowing instances to be started successfully after deploying an overcloud with the director.

BZ#1298247

The Director now supports new parameters that control whether to disable or enable the following OpenStack Networking services:

* dhcp_agent
* l3_agent
* ovs_agent
* metadata_agent

This enhancement allows the deployment of Neutron plug-ins that replace any of these services. To disable all of these services, use the following parameters in your environment file:

  NeutronEnableDHCPAgent: false
  NeutronEnableL3Agent: false
  NeutronEnableMetadataAgent: false
  NeutronEnableOVSAgent: false

BZ#1288475

A bug in the Identity service's endpoint registration code failed to mark the Telemetry service as SSL-enabled. This prevented the Telemetry service endpoint from being registered as HTTPS. This update fixes the bug: the Identity service now correctly registers Telemetry, and Telemetry traffic is now encrypted as expected.

BZ#1319878

When using Linux kernel mode for bridges and bonds (as opposed to Open vSwitch), the physical device was not detected for the VLAN interfaces. This, in turn, prevented the VLAN interfaces from working correctly. 

With this release, the os-net-config utility automatically detects the physical interface for a VLAN as long as the VLAN is a member of the physical bridge (that is, the VLAN must be in the 'members:' section of the bridge). As such, VLAN interfaces now work properly with both OVS bridges and Linux kernel bridges.

BZ#1316730

In previous releases, when VLAN interfaces were placed directly on a Linux kernel bond with no bridge, it was possible for the VLANs to start before the bond. When this occurred, the VLANs failed to start. With this release, the os-net-config utility now starts the physical network (namely, bridges first, then bonds and interfaces) before VLANs. This ensures that the VLANs have the interfaces necessary to start properly.

BZ#1271250

In previous releases, a bug made it possible for failed nodes to be marked as available. Whenever this occurred, deployments failed because nodes were not in a proper state. This update backports an upstream patch to fix the bug.

BZ#1288544

Previously, bulk introspection only printed on-screen errors, but never returned a failure status code. This prevented introspection failures from being detected. This update changes the status code of errors to non-zero, which ensures that failed introspections can now be detected through their status codes.

BZ#1261920

Previously, bulk introspection operated on nodes currently in maintenance mode. This could cause introspection to fail, or even break node maintenance (depending on the reason for node maintenance). With this release, bulk introspection now ignores nodes in maintenance mode.

BZ#1246589

In older deployments using the python-rdomanager-oscplugin (not the python-tripleoclient) for Overcloud deployment, the dhcp_agents_per_network parameter for neutron was set to a minimum of 3, even in the case of a non-HA single controller deployment. This meant the dhcp_agents_per_network was set to 3 when deploying with only 1 Controller. This fix takes into account the single Controller case. The director sets at most 3 dhcp_agents_per_network and never more than the number of Controllers. Now if you deploy in HA with 3 or more controller nodes, the dhcp_agents_per_network configuration parameter in neutron.conf on those Controller nodes will be set to '3'. Alternatively if you deploy in non-HA with only 1 Controller, this same dhcp_agents_per_network parameter will be set to '1'.

BZ#1293979

Updating packages on the Undercloud left the Undercloud in an indeterminate state. This meant some Undercloud services were disabled after the package update and could not start again. As a workaround, run 'openstack undercloud install' to reconfigure all Undercloud services. After the command complete, the Undercloud services operate normally.

BZ#1234601

The Ramdisk and Kernel images booted without specifying a particular interface. This meant the system booted from any network adapter, which caused problems when more than one interface was on the Provisioning network. In those cases it was necessary to specify which interface the system should use to boot. The interface specified should correspond to the interface which carried the MAC address from the instackenv.json file.

As a workaround, copy and paste the following block of text as the root user into the director's terminal.This creates a systemd startup script sets these parameters on every boot.

The script contains a sed command which includes "net0/mac". This sets the director to use the first Ethernet interface. Change this to "net1/mac" to use the second interface, and so on.

The director requires the 'baremetal' flavor, even if unused. Without this flavor, the deployment fails with an error. Now the Undercloud installation automatically creates the 'baremetal' flavor. With the flavor in place, the director does not report the error.

Previously, the os_tenant_name variable in the Ceilometer configuration was incorrectly set to the 'admin' tenant instead of the 'service' tenant. This caused the ceilometer-central-agent to fail with the error "ERROR ceilometer.agent.manager Skipping tenant, keystone issue: User 739a3abf8504498e91044d6d2a6830b1 is unauthorized for tenant d097e6c45c494c2cbef4071c2c273a58". Now, Ceilometer is correctly configured to use the 'service' tenant.

Previously, after upgrading the undercloud, there was a missing restart of the openstack-nova-api service, which would cause upgrades of the overcloud to fail due to a timeout that would report the error "ERROR: Timed out waiting for a reply to message ID 84a44ca3ed724eda991ba689cc364852". Now, the openstack-nova-api service is correctly restarted as part of the undercloud upgrade process, allowing the overcloud upgrade process to proceed without encountering this timeout issue.
