perfSONAR User Q&A and Other Discussion

[eddie legbed <>]

Hi Szymon,

A reload of the node seems to clear the clear the results section issue.

With regards to Ls , I see this behaviour consistent with all my ps nodes. Even when perfsonar-lsregistration daemon is stopped.

pS attempts to determine the primary address and sends a get to os1.es.net although this is not configured anywhere. Then it attempts to find the host in a non-existent Ls

I find that the GUI page does not load until all these actions are carried out and failed. 

Is there a way to disable pS from going to es and disable querying a non-existent Ls?

Regards,

Ade

So seems it's running. Is your GUI still stuck on loading?

I stopped/disabled perfsonar-lsregistrationdaemon.service but it seems pS is still looking for a Ls

Was this message just once or is repeating? I was trying to reproduce this behaviour and sopping the service on my host prevented any log entries.

Best regads,
