Hi, Dear all:

    My ovs was ok before, but recently, my ovs got an error when i add-port in bridge:

ovs-vsctl add-br br0

ovs-vsctl add-port br0 port0

ovs-vsctl: Error detected while setting up 'port0'.  See ovs-vswitchd log for details.

My ovs version is 2.3.90, the problem cannot be resloved even when i reinstall the ovs. The log in the /var/log/openvswitch/ovs-vswitchd.log show :

Isn’t that tricky for a person who is trying to connect ovs to controller? Its like you may or may not see the node in operations based whether or not it succeeds or fails to update.However the ovs would show conencted=true and manager ip, with no data in operations.  :-)

IMO connection received is exclusive event for creating ovsdb node and then registering for callbacks for update. Current implementation seems more logical(to me) than changing it for 1 case of IID creation. 

My further 2 cents on iid serialization/deserialization:

In general, IMO  this IID serialization and deserialization is a risk. And should be avoided if possible.  If a system is running for long period of time and for some reason someone connected disconnected same ovs nodes with diff setting once with IID passed to it once without. Your config would be looking very out of synch of your operations. On top of that if the apps that are trying to use this data programmatically would most likely fail to take care of such situations. 

Also different apps may choose different strategies to generate iids and would be impossible for them to coexist.

So having  only one way of creating IIDs would help in longer run. If one wants avoid iid  generation while connecting to OVS or creating bridges then we can always expose RPCs for that. However, if one wants to use CONFIG store to configure, then they have to build appropriate iid.

Thoughts?

I am not sure if that is the best thing to do.

I had an idea last night as I was falling asleep that might be interesting.

How about we create the ovsdb-node in operational with the OpenVSwitchUpdateCommand (which should get tripped with the original dump of data from ovsdb on connect) rather than invoking OvsdbNodeCreatedCommand in the OvsdbConnectionInstance() constructor.  That way you have access to the info you need, don't have to do a select (and thus a new round trip) etc.

Thoughts?

Let me know if its ok to change the signature and pass OvsdbClient.

However, I believe still we would need to run a select statement to get the system-id in OvsdbNodeCreateCommand.

Please let me know your thoughts.

The config/operational synch is best handled a little differently.

When you try to config an ovsdb-node to connect... you don't *really* know the systemid... just the IP:port.

The way we solved this for bridges, and the way I'd advocate solving it here is:

1)  If you are configing a ovsdb-node, write its iid to the external-ids of the openvswitch table

2)  When you get an openvswitch table, if it has an iid in its external-ids, use that in the operational data store as its iid

3)  If you don't get an iid in its external-ids... use some reasonable heuristic to contruct one.

For #3... I don't currently see a reason *not* to use systemid presuming its guaranteed unique and we contruct some kind of reasonable

Uri from it.

Hi,

In my opinion, the we can replace the node-id of the ovsdb node in md-sal to contain system_id from external properties. This would make sure that the config and operation store are in synch in case the controller reconnects to the same ovs in tcp mode.

I’ll make these changes, update postman collection and submit for approval.

This can be done in OvsdbNodeCreateCommand. The issue I see there is changing the signature of the OvsdbNodeCreateCommand’s constructor.

Let me know if its ok to change the signature and pass OvsdbClient.

However, I believe still we would need to run a select statement to get the system-id in OvsdbNodeCreateCommand.

Please let me know your thoughts.

Thanks

Hi Ed,

The way I am implementing this is:

In OvsdbConnectionManager’s connected method, I’ll set system-Id from external_ids of open_Vswitch table in ConnectionInfo key (I’ll modify yang to add systemId field in connectionInfo to add system-id). Therefore to get the system-id in OvsdbConnectionManager’s connected method, I need to execute select operation on open_Vswitch table. 

So later when OvsdbNodeCreateCommand is called with ConnectionInfo, I’ll have the systemId to write to operation store.

Please let me know your thoughts on this approach.

Why are you doing a select? (curious) :)

Hi,

While implementing this use case I need some help using the select operation of ovsdb library. I am trying to read the Open_vSwitch table to get the data in external-ids. I am doing the following:

OpenVSwitch ovs = TyperUtils.getTypedRowWrapper(dbSchema, OpenVSwitch.class);

                transaction.add(op.select(ovs.getSchema()));

                ListenableFuture<List<OperationResult>> results = transaction.execute();

List<OperationResult> resultList = results.get();

I am getting resultList as:

[OperationResult [count=0, uuid=null, rows=[Row [columns={}]], error=null, details=null]]

Query sent to Ovs db is:

ovsdb-client transact '["Open_vSwitch",{"op":"select", "table":"Open_vSwitch", "columns":[],"where": []}]'

However, I want to send:

ovsdb-client transact '["Open_vSwitch",{"op":"select", "table":"Open_vSwitch", "columns":["external_ids"],"where": []}]'

It would be very helpful if someone could provide pointers on how to set column in select operation.

The config/operational synch is best handled a little differently.

When you try to config an ovsdb-node to connect... you don't *really* know the systemid... just the IP:port.

The way we solved this for bridges, and the way I'd advocate solving it here is:

1)  If you are configing a ovsdb-node, write its iid to the external-ids of the openvswitch table

2)  When you get an openvswitch table, if it has an iid in its external-ids, use that in the operational data store as its iid

3)  If you don't get an iid in its external-ids... use some reasonable heuristic to contruct one.

For #3... I don't currently see a reason *not* to use systemid presuming its guaranteed unique and we contruct some kind of reasonable

Uri from it.

Hi,

In my opinion, the we can replace the node-id of the ovsdb node in md-sal to contain system_id from external properties. This would make sure that the config and operation store are in synch in case the controller reconnects to the same ovs in tcp mode.

I’ll make these changes, update postman collection and submit for approval.

What was the solution for the cases where ODL connects to the ovsdb nodes? In that case odl only has the ip:port of the node to make the outgoing connection.

The idea in this thread is to use the system-id, but that looks to only cover the case where the ovsdb node connects to ODL.

Thanks, Sam
