Public bug reported: The Neutron Server code will in some circumstances call out to the `ovsdb-client` binary for OVN database maintenance. [0]
This change appeared recently but has been backported all the way to OpenStack Train [1]. The neutron-server does currently not depend on openvswitch-common and as such the call will fail with log entries like: 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event [req-46b888be-d233-4aec-a4d4-3ba04d220f64 - - - - -] Unexpected exception in notify_loop: FileNotFoundError: [Errno 2] No such file or directory: 'ovsdb-client' 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event Traceback (most recent call last): 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3/dist-packages/ovsdbapp/event.py", line 143, in notify_loop 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event match.run(event, row, updates) 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3/dist-packages/neutron/plugins/ml2/drivers/ovn/mech_driver/ovsdb/ovsdb_monitor.py", line 347, in run 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event self.driver.delete_mac_binding_entries(row.external_ip) 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3/dist-packages/neutron/plugins/ml2/drivers/ovn/mech_driver/mech_driver.py", line 1068, in delete_mac_binding_entries 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event return processutils.execute(*cmd, 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3/dist-packages/oslo_concurrency/processutils.py", line 383, in execute 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event obj = subprocess.Popen(cmd, 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3/dist-packages/eventlet/green/subprocess.py", line 58, in __init__ 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event subprocess_orig.Popen.__init__(self, args, 0, *argss, **kwds) 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3.8/subprocess.py", line 858, in __init__ 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event self._execute_child(args, executable, preexec_fn, close_fds, 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event File "/usr/lib/python3.8/subprocess.py", line 1704, in _execute_child 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event raise child_exception_type(errno_num, err_msg, err_filename) 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event FileNotFoundError: [Errno 2] No such file or directory: 'ovsdb-client' 2022-02-08 13:38:23.053 386820 ERROR ovsdbapp.event 0: https://github.com/openstack/neutron/blob/2999b8e579dd9d5ac6ee5f0ec77ff5607b6a1143/neutron/plugins/ml2/drivers/ovn/mech_driver/mech_driver.py#L1113 1: https://review.opendev.org/q/Id84bf17953527c415d611bfc198038fb6f811de3 ** Affects: neutron (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960319 Title: Missing dependency for neutron-server: openvswitch-common To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/neutron/+bug/1960319/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
