We introduce support for running both the NB and SB OVN databases in clustered mode. This OVN DBs clustered mode is based on OVNs own clustering protocol and does not rely on pacemaker. Clustering the two OVN databases increases reliability. The cluster works in active-active mode and has the potential to be more resilient and performant. See https://docs.openvswitch.org/en/latest/ref/ovsdb.7/#clustered-database-service-model for more information.

features:
|
|
- |
|
|
Added OVN DBs clustering support. In this service model, a clustered
|
|
database runs across multiple hosts in multi-active mode.
|
|
upgrade:
|
|
- |
|
|
Upgrades from OVN non-HA and OVN DBs pacemaker to OVN DBs clustered are
|
|
currently not supported.
|
|
security:
|
|
- |
|
|
The OVN database servers in an OVN DBs clustering and TLS-everywhere
|
|
deployment will listen on all IP addresses (0.0.0.0). This is a caveat that
|
|
can only be addressed once RHBZ 1952038 is fixed.
