[opencontrail-dev] cassandra server switchover

[Suresh Kumar S]

Hi, 

In the contrail-collector config file, we can specify multiple cassandra 
servers. 
What is the purpose of it ? 


contrail-collecter.conf snippet 

# IP address and port to be used to connect to cassandra. 
# Multiple IP:port strings separated by space can be provided 
# cassandra_server_list=127.0.0.1:9042 

Does contrail support server switchover, I mean when the current server is not 
reachable, will it switch to the new server(mentioned in the config) ? 

Thanks 
suresh

[Rahul Sharma]

Hi Mani,
How did you install it?  There are no feature packages (repo),  eg 
contrail-web-controller or the path to this is not set in your 
contrail-web-core config.global.js webui conf file.

[opencontrail-dev] CI Update (Re: CI will be offline for Thu)

[Karl Klashinsky]

CI is back up, but we are seeing failures for all R3* reviews.
This breakage is not related to the upgrade, FYI.

Working on fixing the R3* issues.

Re: [opencontrail-dev] [Users] taskset cpu affinity not considered when starting vrouter-dpdk eventhough its set in contrail-vrouter-dpdk.ini

[Rajagopalan Sivaramakrishnan]

For MPLS-over-UDP, the NIC does RSS. For MPLS-over-GRE, vrouter-dpdk hashes and 
distributes the packets across CPU cores in software. It doesn’t need a 
separate interface (such as pkt3) with DPDK. The kernel module needs it as it 
uses the Linux RPS functionality, which requires an interface.

Wow!! thanks Raja,

Never thought about that

after checking the logs its clear now, 5 threads are not assigned to any CPU 
and rest are all pinned 1:1   :)

Regarding distribution of packets to to those cores,in kernel mode vrouter 
there is pkt3 interface to do packet distribution,in DPDK-vrouter i dont see 
that interface in vif --list,how is it achieved in DPDK-Vrouter with out this 
interface .


Thanks again

Hi Kevin,
The forwarding threads with vrouter-dpdk use the cores specified in the 
testbed file. Other threads in vrouter-dpdk (which don’t consume as much CPU) 
can run on any core. Please see “—lcores” argument in 
/var/log/contrail/contrail-vrouter-dpdk-stdout.log.

eventhough its set in contrail-vrouter-dpdk.ini

Hello All,
I have contrail with DPDK  up and running but i think taskset set in 
"contrail-vrouter-dpdk.ini" is not considered and its using default cpu 
affinity of "fff" on compute nodes
taskset -c -p `pidof contrail-vrouter-dpdk`
pid 46767's current affinity list: 0-47

Version:

3.0.2.0-51


configuration:

cat /etc/contrail/supervisord_vrouter_files/contrail-vrouter-dpdk.ini
[program:contrail-vrouter-dpdk]
command=taskset  1,5,6,7  /usr/bin/contrail-vrouter-dpdk --no-daemon 
--vr_mpls_labels 5000 --vr_flow_entries=2097152 --vdev 
"eth_bond_bond1,mode=0,xmit_policy=l34,socket_id=0,mac=00:11:0a:6d:06:94,slave=:08:00.0,slave=:81:00.1"
 --vlan_tci "14" --vlan_fwd_intf_name "bond1" --socket-mem 1024,1024
priority=410
autostart=True
killasgroup=True
stdout_capture_maxbytes=1MB
redirect_stderr=True
stdout_logfile=/var/log/contrail/contrail-vrouter-dpdk-stdout.log
stderr_logfile=/var/log/contrail/contrail-vrouter-dpdk-stderr.log
exitcodes=0
loglevel=debug


on Contrail.log i dont see taskset being used to start dpdk-vrouter and hence i 
suppose the issue is  in "vrouter-pre-start.sh" .Could this be a bug.

if i manually execute above command then taskset gives proper result.

Thanks for any help

Regards,
Kevin
