New Features¶

• A newtripleo::profile::base::cinder::volume::rbd::extra_optionsparameter adds the ability to configure additional options for usewith cinder RBD backends.

New Features¶

• Add ability to specify the memcache_security_strategy andmemcache_secret_key for keystone authtoken middleware. The keysused by individual services are hashed with a salt (the servicename), to isolate them.

• Add ability to specify memcached port for all services. The port defaultsto hiera(‘memcached_authtoken_port’, 11211) for authtoken middleware andhiera(‘memcached_port’, 11211) for other uses.

• Add parameter for setting monitor interval for ovndbs (default is 30s)

Bug Fixes¶

• libvirt 6.8.0 introduces virt-ssh-helper which prepends the libvirtssh command with a “which virt-ssh-helper”. libvirt used to firstcheck fornc (netcat). But these two libvirt commits[1][2] have nowchanged it to first look forvirt-ssh-helper, if it not available,then fall back tonc. This trips up the ‘nova-migration-wrapper’ asit does not support virt-ssh-helper atm.Until this is implemented, this change force to use “netcat” (nc) byappending to the migration URI: “&proxy=netcat”[1]https://libvirt.org/git/?p=libvirt.git;a=commit;h=f8ec7c842d (rpc:use new virt-ssh-helper binary for remote tunnelling, 2020-07-08)[2]https://libvirt.org/git/?p=libvirt.git;a=commit;h=7d959c302d (rpc:Fix virt-ssh-helper detection, 2020-10-27)

New Features¶

• This change introduces two hiera keys that allow an operator to specifywhich NIC (or NICs) the VIPs will be bound to. One hiera key has global effect(tripleo::pacemaker::force_nic) and forces all VIPs to listen to that NIC.There is also the possibility to override that for specific VIPs with theforce_vip_nic_overrides hiera hash.This change is only useful for deployments where BGP is used to advertiseIP addresses from the host across multiple L3 networks.

Bug Fixes¶

• It is now possible to override theenabled_share_protocolsconfiguration for the Shared File Systems service (manila) with thehiera parametermanila_enabled_share_protocols.

New Features¶

• Added support for VxFlexOS backend driver

Deprecation Notes¶

• Keepalived is deprecated in Ussuri and will be removed in the next cycle.

• Resource tripleo::profile::base::cinder::volume::dellemc_vxflexos will be removed in W-Release.

New Features¶

• Add Dell EMC SC backend Cinder driver options. Supports both iSCSI and FC volume drivers and multiple backends as well.

• Add Dell EMC XtremIO backend Cinder driver options. Supports both iSCSI and FC volume drivers and multiple backends as well

Deprecation Notes¶

• ovn_db_host and ovn_nb_port from tripleo::profile::base::octavia::apiare now deprecated and will be removed in the future release. Please useovn_db_host and ovn_nb_port from tripleo::profile::base::octavia::provider::ovninstead.

• Support for OpenDaylight has been removed because its templates andenvironment files are already removed in tripleo-heat-templates.

• Resource tripleo::profile::base::cinder::volume::dellsc will be removed in V-Release.

New Features¶

• Added tripleo::profile::base::octavia::provider::ovn for configuring OVN driverproperties, including protocol.

• Add support for configuring the glance-api service with multiple storebackends. The primary backend becomes the service’s default backend, andadditional backends may be specified using an optional ‘multistore_config’hash.

• Add new PowerMax backend Cinder driver options. Supports both iSCSI and FC volume drivers and multiple backends as well.

• Add support to change virtlogd config options.New hieradata tripleo::profile::base::nova::libvirt::virtlogd_config canbe used to override virtlogd config options.

Deprecation Notes¶

• Theenable_cache andcache_backend intripleo::profile::base::nova class were removed because now theseparameters are defined in tripleo-heat-templates.

• tripleo::profile::base::nova::api::nova_api_wsgi_enabled andtripleo::profile::base::nova::api::nova_metadata_api_wsgi_enabled areremoved, because the issue in nova was already resolved and usingstandalone eventlet server is discouraged.

• Resource tripleo::profile::base::cinder::volume::dellemc_vmax_iscsi is no longer supported.

New Features¶

• Adds ceph_dashboard endpoint and ceph_dashboard_port to properlyexpose the ceph-dashboard frontend service

New Features¶

• This parameter sets inactive probe interval of the JSON sessionfrom ovn-metadata to the OVN SB database. By default this itis 5s which not be sufficient in loaded systems or during highcontrol-plane activity spikes, leading to unnecessary reconnectionsto OVSDB server. Now it is extended by default to 1 min and it isconfigurable by param OVNRemoteProbeInterval.

• Under pressure, the default monitor timeout value of 20 seconds is notenough to prevent unnecessary failovers of the ovn-dbs pacemaker resource.While spawning a few VMs in the same time this could lead to unnecessarymovements of master DB, then re-connections of ovn-controllers (slaves areread-only), further peaks of load on DBs, and at the end it could lead tosnowball effect. Now this value can be configurable by dbs_timeout intripleo::profile::pacemaker::ovn_dbs_bundle and by default is set to 60s.

Bug Fixes¶

• Allow using upper case names for SRIOV interface names.
