Additional info: There's no reason to persist IP information on either of those two bridges, and OVS persists the rest of the information. Thus, there's no reason at all to create ifcfg-br-tun or ifcfg-br-int. The fix here is to make sure that Staypuft / Foreman, like Packstack, never create those files. The actual code that creates the bridge file is in vswitch/lib/puppet/provider/vs_port/ovs_redhat.rb line 61 (function create_bridge_file) removing the function and any reference worked for me (no more loops) vswitch redhat provider is undergoing heavy rewriting - https://review.openstack.org/#/c/94504 bridge file creation was removed in the new version This problem is fixed as a patch in the RHEL OSP openstack-puppet-modules RPM, i'm creating a version for RDO that includes this patches. |
Created attachment 920539 [details] logs Description of problem: neutron/manifests/agents/ovs.pp creates /etc/sysconfig/network-scripts/ifcfg-br-{int,tun}. This seems to be problematic. After installing openstack using astapor and foreman (without staypuft plugin), having those files created leads to a loop in which udev continuously adds and deletes the bridges, making it impossible to use them. Removing ifcfg-br-* files stopped the loop, and bridge were correctly created and usable However, packstack installations seem not to be affected by this behaviour Version-Release number of selected component (if applicable): both production and stage repos are affected, creation in still present in source Version : 2014.1.1 Release : 3.el6 Version : 2014.1 Release : 18.el6 How reproducible: 100% Steps to Reproduce: 1. Install openstack with neutron using astapor and foreman 2. Soon after neutron-openvswitch-agent service in either networker or compute node is started, check /var/log/oepnvswitch/ovs-vswitchd.log 3. check udevadm monitor too Actual results: Endless loop in br-tun creation Expected results: br-tun correctly created Additional info: some logs attached. You can see things stabilizing at the end of logs, after removing ifcfg files.
