perfSONAR User Q&A and Other Discussion

[Tristan Sullivan <>]

Hi,

In case anyone with the shards problem wants to revive their host before the next release, a workaround is to increase the maximum number of shards:

curl -k --netrc-file pw -X PUT https://localhost:9200/_cluster/settings -H 'Content-Type: application/json' -d '{"persistent": {"cluster.max_shards_per_node": "2000"}}'

Where pw is a file in the directory from which you run the command, in the following format:

machine localhost login admin password {password}

The password can be found in /etc/perfsonar/opensearch/auth_setup.out.

Hi Chris

Alright, ah yeah holy moly the opensciencegrid ain’t looking good,  thank you so much for the info, it helps calm down again. After many frustrating hours.

Then I’m just looking forward for the next release :-)

Hi Joachim, 
 
Much of the WLCG/OSG mesh is down too, so it may well not be a problem with your config:

MaDDash - Monitoring and Debugging Dashboard (opensciencegrid.org

I know some/many hosts have an issue with number of shards - https://github.com/perfsonar/archive/issues/18 - which I think I've heard will be fixed in the next release of perfsonar.

Hey guys

I had a mesh before my summer vacation with 5/6 host working 100% 

And when I get back to work Im lucky if I see 3/6 sometime 2/6 

Pretty unstable Maddash of some reason 

Psconfig are can be found here

https://maddash-01.nordu.net/psconfig/throughput.json

https://maddash-01.nordu.net/psconfig/latency.json

Do one have some spare time to zoom about this mesh with me. 

So I can have an extra pair of eyes looking at it. 

My eyes start to cross each other 

Best regards
