Public bug reported: When the L3 agent is dead, if the gateway is removed, the snat namespace and its rules are not properly cleaned when agent restarts.
Even though the patch https://review.openstack.org/#/c/326729/ addresses the cleanup of the snat namespace, it does not remove the redirect rules and the gateway device from the router namespace when gateway is disabled. When agent restarts the agent does not get the gateway data from the server, and so it is not possible for the agent to clean it properly. In order to clean the snat redirect rules, the gateway data should be cached to the local file system and reused later when necessary. ** Affects: neutron Importance: Undecided Assignee: Swaminathan Vasudevan (swaminathan-vasudevan) Status: In Progress ** Tags: l3-dvr-backlog ** Tags added: l3-dvr-backlog -- You received this bug notification because you are a member of Yahoo!
