[ovs-discuss] EMC lookup disabled but still there some processing going on with emc lookup

Hello everyone I am testing ovs-vswitch caches time spent using intel vtune. I disabled emc lookup using "emc-insert-inv-prob=0" but still I can see emc lookup is not disabled and also there is insertion which takes place into emc also after the packet completes fast-path processing. I am

Re: [ovs-discuss] raft ovsdb clustering

Hi : Just sorted out the correct settings and northd also works in ha in raft. There were 2 issues in the setup: 1. I had started nb db without --db-nb-create-insecure-remote 2. I also started northd locally on all 3 without remote which is like all three northd trying to lock the ovsdb locally.

Re: [ovs-discuss] raft ovsdb clustering

Ali, sorry if I misunderstand what you are saying, but pacemaker here is for northd HA. pacemaker itself won't point to any ovsdb cluster node. All northds can point to a LB VIP for the ovsdb cluster, so if a member of ovsdb cluster is down it won't have impact to northd. Without clustering

Re: [ovs-discuss] ovs-ofctl memory consumption is large compared to flow bundle size [formatting correction]

Thank you so much Ben and team! Assuming it is merged, we will deploy as part of our next OVS upgrade. In the meantime, we have found conjunctive matchers to be a solid workaround to help with limiting the size of the flow bundle, and in turn the consumed memory. On Tue, Mar 20, 2018 at 4:48 PM,

Re: [ovs-discuss] raft ovsdb clustering

:) The only thing is while using pacemaker, if the node that pacemaker if pointing to is down, all the active/standby northd nodes have to be updated to new node from the cluster. But will dig in more to see what else I can find. @Ben: Any suggestions further? Regards, On Wed, Mar 21, 2018 at

Re: [ovs-discuss] raft ovsdb clustering

Thanks Numan: Yup agree with the locking part. For now; yes I am running northd on one node. I might right a script to monitor northd in cluster so that if the node where it's running goes down, script can spin up northd on one other active nodes as a dirty hack. Sure, will await for the inputs

[ovs-discuss] How to enable kernel configuration options NET_CLS_BASIC, NET_SCH_INGRESS, and NET_ACT_POLICE?

Hi I would like to enable ingress policing in my OVS installation inside a Ubuntu 16.04 VM. The installation guide mentions the following: To compile the kernel module on Linux, you must also install the

Re: [ovs-discuss] raft ovsdb clustering

Hi Aliasgar, ovsdb-server maintains locks per each connection and not across the db. A workaround for you now would be to configure all the ovn-northd instances to connect to one ovsdb-server if you want to have active/standy. Probably Ben can answer if there is a plan to support ovsdb locks

Hello, In my environment I have 2 OVS bridges - 1st with datapath type netdev and 2nd with datapath type system and I'd like to connect those 2. I've tried patchport - they does not work[1], but it is mentioned that one can provide such functionality. How much effort would it take to patch OVS,

Re: [ovs-discuss] raft ovsdb clustering

Hi Numan: Just figured out that ovn-northd is running as active on all 3 nodes instead of one active instance as I continued to test further which results in db errors as per logs. # on node 3, I run ovn-nbctl ls-add ls2 ; it populates below logs in ovn-north
