Title:
Open vSwitch commands timeout on gate tests
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
Error 242 occurs fairly often in gate tests:
http://logstash.openstack.org/#eyJzZWFyY2giOiJcIkV4aXQgY29kZTogMjQyXCIgIiwiZmllbGRzIjpbImZpbGVuYW1lIl0sIm9mZnNldCI6MCwidGltZWZyYW1lIjoiNDMyMDAiLCJncmFwaG1vZGUiOiJjb3VudCIsInRpbWUiOnsidXNlcl9pbnRlcnZhbCI6MH0sInN0YW1wIjoxMzg1MzE3OTg4NTQxLCJtb2RlIjoiIiwiYW5hbHl6ZV9maWVsZCI6IiJ9
This is actual an ALARM_CLOCK error [142] (rootwrap adds 100 to the
error code), and means open vswitch times out; as the default timeout
is 2 seconds there is a chance they could occur quite often in a
rather stressful scenario as the one represented by parallel tests in
tenant isolation.
It might be therefore advisable to allow for a configurable timeout on
ovs commands, and increase this timeout for gate tests.
Kernel logs do not provide enough additional information.
It might be also worth adding open vswitch logs to the logs collected by
devstack-gate
