commit 5a7c12f245fd665de5a0364059e4ad918def3e12 Author: Swaminathan Vasudevan <[email protected]> Date: Thu Jun 14 13:49:23 2018 -0700 DVR: Self recover from the loss of 'fg' ports in FIP Namespace Sometimes we have seen the 'fg' ports within the fip-namespace either goes down, not created in time or getting deleted due to some race conditions. When this happens, the code tries to recover itself after couple of exceptions when there is a router_update message. But after recovery we could see that the fip-namespace is recreated and the 'fg-' port is plugged in and active, but the 'fpr' and the 'rfp' ports are missing which leads to the FloatingIP failure. This patch will fix this issue by checking for the missing devices in all router_updates.

When this happens, the code tries to recover itself after couple of exceptions when there is a router_update message. But after recovery we could see that the fip-namespace is recreated and the 'fg-' port is plugged in and active, but the 'fpr' and the 'rfp' ports are missing which leads to the FloatingIP failure. So we need to fix this issue, if this happens, then it should check for all the ports within the 'fipnamespace' and recreate the necessary plumbing. Here is the error log we have been seeing when the 'fg' port was missing. http://paste.openstack.org/show/723505/ To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1776984/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
