This section describes how to configure arbitrary Galera parameters using the
wsrep_provider_options Galera variable. For details, see
Galera parameters.
To configure arbitrary Galera parameters:
Open your project Git repository with the Reclass model on the cluster level.
In openstack/database/init.yml, specify wsrep_provider_options
as required. For example:
parameters:
...
galera:
master:
wsrep_provider_options:
gcomm.thread_prio: "rr:2"
slave:
wsrep_provider_options:
gcomm.thread_prio: "rr:2"
...
Log in to the Salt Master node.
Apply the changes to Galera:
salt -C 'I@galera:master or I@galera:slave' saltutil.refresh_pillar
salt -C 'I@galera:master or I@galera:slave' state.apply galera
