openstack/kolla-ansible — Week of 2026-08-01

Cinder and Glance backends. The largest functional change moves Cinder backend variables into group_vars/all, landing on master and backporting to a stable branch. Glance gains an enable_cinder_backend_privileged toggle for the cinder store, and a fix registers keystoneauth options for the [glance] config group so they're recognised at runtime.

MariaDB and OpenSearch recovery. Cluster recovery got a substantive rework: MariaDB cluster recovery was fixed, the WSREP sync wait was made defensive, and a new "wait for slaves to sync before the recovery master restart" step landed across three branches. OpenSearch upgrades now wait for recovery to complete — a change that was landed, reverted twice, and re-landed within the window (999109), then paired with voting opensearch CI jobs on gate.

Stability and fixes. An NFS mount leak was fixed, iterable container restarts were narrowed to only changed containers (backported), the valkey-sentinel image tag was corrected, ProxySQL's keepalived healthcheck now uses the MySQL protocol, and Keystone allows multiple OIDCXForwardedHeaders options across three branches. An old enable_ceph precheck was retired, and docs warn about matching RadosGW options with external Ceph.

Platform and tooling. CentOS Stream 10 support was dropped. Elsewhere, an AI/LLM assistant guide (~200 lines of docs) was added, CI installs kernel-modules-extra across four branches, and a Neutron wrapper container check no longer fails the gate.
