From ac7fd699468ad9a02b250e5ef890aff8a03ce1bf Mon Sep 17 00:00:00 2001 From: Alexandru Avadanii Date: Fri, 25 Jan 2019 21:28:27 +0100 Subject: [ovs] Start ovs services before networking Fix broken systemd service unit dependecies: - OVS should start before networking service; - OVS ports & bridges should not be automatically ifup-ed by networking service to avoid races, so drop 'auto' for both (OVS ports are automatically handled when part of an OVS bridge); - explicitly ifup OVS bridges as part of networking service, but after all Linux interfaces have been handled; - use 'allow-ovs br-prv' to let OVS handle br-prv and avoid another race condition; While at it, fix some other related issues: - make OVS service start after DPDK service (if present); - bump OVS-DPDK compute VMs RAM since since switching from MTU 1500 to jumbo frames for virtual PODs a while ago failed to do so [1]; - avoid creating conflicting reclass linux.network.interfaces entries for OVS ports by using their name (drop 'ovs_port_' prefix): * for untagged networks they will override existing common defs; * for tagged networks, they will create separate entries; - DPDK scenarios: make gtw01 br-prv members OVS ports to avoid race conditions after node reboot by letting OVS handle them; [1] https://developers.redhat.com/blog/2018/03/16/\ ovs-dpdk-hugepage-memory/ Change-Id: I0266ba67f3849b6f7e331a758146b331730bae55 Signed-off-by: Alexandru Avadanii --- .../classes/cluster/mcp-ovs-dpdk-noha/openstack/gateway.yml.j2 | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'mcp/reclass/classes/cluster/mcp-ovs-dpdk-noha') diff --git a/mcp/reclass/classes/cluster/mcp-ovs-dpdk-noha/openstack/gateway.yml.j2 b/mcp/reclass/classes/cluster/mcp-ovs-dpdk-noha/openstack/gateway.yml.j2 index 8d11eedcd..c45b75569 100644 --- a/mcp/reclass/classes/cluster/mcp-ovs-dpdk-noha/openstack/gateway.yml.j2 +++ b/mcp/reclass/classes/cluster/mcp-ovs-dpdk-noha/openstack/gateway.yml.j2 @@ -20,8 +20,13 @@ parameters: network: interface: {{ nm.ctl01.nic_private }}: + ovs_port_type: OVSPort + type: ovs_port + bridge: br-prv ovs_bridge: br-prv br-prv: enabled: true type: ovs_bridge mtu: ${_param:interface_mtu} + use_interfaces: + - {{ nm.ctl01.nic_private }} -- cgit 1.2.3-korg
