commit 139b496ef957364caee6861fd16676cdfb76a38b Author: Reedip <[email protected]> Date: Mon Nov 11 10:54:42 2019 +0900 Dont schedule Network, respecting network_auto_schedule config Currently, if dhcp mapping from a network is removed, it is reassigned to the network. This is because of the Network Scheduler's schedule function, which considers balancing the networks with the agents, whether enable_dhcp is set on its subnets or not. It does not take into account the network_auto_schedule config option. This is particularly disturbing when considering backends which have their provide their own DHCP. With this patch, if network_auto_schedule is set to False, networks wont be automatically scheduled to DHCP Agents. If DHCP is to be mapped to a network, it can be mapped using the CLI itself. While it may seem that this change is breaking what is already working, but as mentioned earlier, if there are network backends which provide DHCP support themselves, they wont need the automatic mapping, which the term "network_auto_schedule" actually stands for. Closes-Bug: #1647421 Change-Id: If1a6a2a174d0f737415efa2abce518722316a77b ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1647421 Title: Neutron attempts to schedule DHCP agents even when intentionally not in use Status in networking-ovn: Confirmed Status in neutron: Fix Released Bug description: OVN has its own native support for DHCP, so the Neutron DHCP agent is not in use. When networks get created, we see warnings in the log about Neutron still trying to schedule DHCP agents. We should be able to disable this code path completely when the DHCP agent is intentionally not in use. 2016-12-05 16:44:12.252 23149 WARNING neutron.scheduler.dhcp_agent_scheduler [req-038bedd2-fa56-4cfb-af68-8a36f39a2e9c 560fda6bf041441581ea756be353433c 21888697d4914989af439a25ebda0b76 - - -] No more DHCP agents 2016-12-05 16:44:12.253 23149 WARNING neutron.api.rpc.agentnotifiers.dhcp_rpc_agent_api [req-038bedd2-fa56-4cfb-af68-8a36f39a2e9c 560fda6bf041441581ea756be353433c 21888697d4914989af439a25ebda0b76 - - -] Unable to schedule network 45d29a60-a672-429f-b7d7-551ee985c8ca: no agents available; will retry on subsequent port and subnet creation events.
