ovn-ctl(8) OVN Manual ovn-ctl(8)
ovn-ctl - Open Virtual Network northbound daemon lifecycle
utility
ovn-ctl [options] command [-- extra_args]
This program is intended to be invoked internally by Open Virtual
Network startup scripts. System administrators should not
normally invoke it directly.

Any options after ’-’ will be passed on to the binary run by
command with the exception of start_northd, which can have
options specified in ovn-northd-db-params.conf. Any extra_args
passed to start_northd will be passed to the ovsdb-servers if
--ovn-manage-ovsdb=yes
Following are the optional configuration files. If present, it
should be located in the etc dir
ovnnb-active.conf
If present, this file should hold the url to connect to the
active Northbound DB server
tcp:x.x.x.x:6641
ovnsb-active.conf
If present, this file should hold the url to connect to the
active Southbound DB server
tcp:x.x.x.x:6642
ovn-northd-db-params.conf
If present, start_northd will not start the DB server even if
--ovn-manage-ovsdb=yes. This file should hold the database url
parameters to be passed to ovn-northd.
--ovnnb-db=tcp:x.x.x.x:6641 --ovnsb-db=tcp:x.x.x.x:6642

# ovn-ctl run_nb_ovsdb

detach option, making it to block until ovsdb-server exits. This
command will be useful for starting the OVN sb ovsdb-server in a
container.
# ovn-ctl run_ic_nb_ovsdb
This command runs the OVN IC-NB ovsdb-server without passing the
detach option, making it to block until ovsdb-server exits. This
command will be useful for starting the OVN IC-NB ovsdb-server in
a container.
# ovn-ctl run_ic_sb_ovsdb
This command runs the OVN IC-SB ovsdb-server without passing the
detach option, making it to block until ovsdb-server exits. This
command will be useful for starting the OVN IC-SB ovsdb-server in
a container.

Avoiding automatic clustered OVN database schema upgrade
If you desire more control over clustered DB schema upgrade, you
can opt-out of automatic on-start upgrade attempts with
--no-db-cluster-schema-upgrade.
Start OVN NB and SB clustered databases on host with IP x.x.x.x
without schema upgrade
# ovn-ctl start_nb_ovsdb --db-nb-cluster-local-addr=x.x.x.x
--no-db-cluster-schema-upgrade # ovn-ctl start_sb_ovsdb
--db-sb-cluster-local-addr=x.x.x.x --no-db-cluster-schema-upgrade
Trigger clustered DB schema upgrade manually
# ovsdb-client convert unix:/var/run/ovn/ovnnb_db.sock
/usr/local/share/ovn/ovn-nb.ovsschema # ovsdb-client convert
unix:/var/run/ovn/ovnsb_db.sock
/usr/local/share/ovn/ovn-sb.ovsschema
