Issue after setting dataplane workers 1>
-
Hi there,
We were experimenting with some of the features and wanted to see what multiple cores would do. After setting the dataplane workers to 2, the vpp configuration kind of lost it.
At this point we are not able to use the cli anymore ( tnsr.sock is not present ), and VPP does not seem to pickup the interfaces anymore.
Is this a known thing? Am I doing something wrong?
Regards,
Robert

We have seen some issues with >1 worker but nothing like that.
How did you set the worker count? Are you certain you used the correct syntax?
We have TNSR CLI commands to set the workers in 19.05 which is due out shortly, before that you'd have to modify the VPP startup config by hand, which could be easy to do incorrectly.
-
I set the workers by doing :
dataplane cpu workers 2
Which funny enough spawns 3 processes. But which process creates the tnsr.sock?
-
The worker threads are extra processes above the main thread. The main thread is always there, handling the main set of tasks, and workers can be used to spread the load.
On 19.05 the functionality has been improved a bit, you can set CPU affinity and you have more control over how workers are allocated.
With no workers set, you'll see this:
tnsr# show dataplane cpu threads Threads master tnsr# show dataplane cpu threads ID Name Type PID LCore Core Socket -- -------- ---- ----- ----- ---- ------ 0 vpp_main 27301 1 0 0 tnsr#And then if you increase the worker count:
tnsr(config)# dataplane cpu workers 2 tnsr(config)# service dataplane restart tnsr(config)# show dataplane cpu threads ID Name Type PID LCore Core Socket -- -------- ------- ----- ----- ---- ------ 0 vpp_main 28921 1 0 0 1 vpp_wk_0 workers 28943 0 2 0 2 vpp_wk_1 workers 28944 2 8 0The docs for 19.05 also cover this more thoroughly.
I haven't seen it behave as you describe, however. Can you share the contents of your
/etc/vpp/startup.conf? -
I just checked and my version is tnsr-v19.02.1-1.. I guess that explains some of the weirdness
My current startup config :
unix {
nodaemon
log /tmp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
gid vpp
}statseg {
socket-name /run/vpp/stats.sock
}api-trace {
on
}api-segment {
gid vpp
}nat {
endpoint-dependent
} -
19.05 isn't out yet, but will be very soon :-)
That config looks fine, does it look the same with the extra workers? It should only differ by the addition of a CPU stanza with the workers line.

@jimp said in Issue after setting dataplane workers 1>:

Yes thats the only difference. But I can't figure out why the tnsr.sock and tnsr.pid are gone. I also removed the workers configuration from the running and startup files. After a reboot still the same behaviour :(
-
Do you get any errors when stopping or starting any of the individual TNSR services? See https://docs.netgate.com/tnsr/en/latest/basics/starting-tnsr.html for more info.
Any errors in the logs? (
sudo journalctl -xe) -
There are definitly some errors.

Unfortunately the formatting there makes things hard to read, but it also looks like the important part of the error(s) is not visible.
For example, this line cuts off:

You had a HUGE amount of spaces in there vs returns.. I fixed it.

So it can't find that interface, which is why it fails to start up. When you can get into the CLI again you might try explicitly configuring the network interfaces in the dataplane, https://docs.netgate.com/tnsr/en/latest/setup/setup-vpp-interfaces.html -- The automatic whitelisting may not be working right on your hardware.
Though 19.05 is out now, you should probably get that and use it.

Hi,
@johnpoz thanks for that ;)
@jimp I tried that ( setting the interfaces again in the cli ). But as soon as I want to set something it starts about the tnsr.sock missing. Basicly with every command.
May 31 16:53:48: clicon_rpc_connect_unix: 409: Protocol error: /var/tnsr/tnsr.sock: config daemon not running?: No such file or directory Protocol error: /var/tnsr/tnsr.sock: config daemon not running?: No such file or directory -
You might need to clear out the config manually (
sudo rm /var/tnsr/*) and then restart the services manually again: https://docs.netgate.com/tnsr/en/latest/basics/starting-tnsr.html#manual-tnsr-service-operations -- you could grab the contents of those db files if you want to keep the old config.Something else besides the worker count had to have changed if it's failing to find an interface that used to be there.
-
@jimp This did the trick. I cleared out the /var/tnsr/ and restarted manually. Now the CLI is usable again. Thanks!
Btw, how can I get the latest version? I requested for a new trial version in order to get it.. But I'm not sure if this is the way to go.
-
If you submit a request for a new trial, someone should be in touch with you to work out the details. New trials are available, but the automated request mechanism was deactivated.
-
Thank you @jimp . I'll just wait for a reaction :)
