perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan (RRZE)" <>]

Hi group,

 

I have been struggling to understand what is the reason for not having some services on a toolkit deployment missing. Unluckily I have not resolved the issue, but also I see there is discrepancy in service status discovery. It appears there are 2 means of service status checks. Please refer to the applied image and excerpt in the logs below:

 

2014/11/12 09:46:37 (64611) INFO> Base.pm:255 perfSONAR_PS::LSRegistrationDaemon::Base::refresh - Record 'Geant Traceroute Responder' is up, refreshing registration

2014/11/12 09:46:38 (64611) INFO> Base.pm:267 perfSONAR_PS::LSRegistrationDaemon::Base::refresh - Record 'Geant OWAMP Measurement Point' is down

 

Please help me find the source of discrepancy and how would I be able to fulfil the requirements of the ls_registration daemon!

 

As a feature request (should I put that as a ticket?):

It would be of great benefit to have both status states available on the local services page!

 

Best regards,

Ivan

Hi Ivan,

 

Let me know if the problem is resolved after you bring the services up. 

 

If not, we can delete the entries manually from the LS and then re-register them.

 

Thanks,

Sowmya

Hi group,

 

In fact I see the problem in the logs. The LS registration service on its discovery process sees my services as down!

 

2014/11/10 09:26:56 (43975) INFO> Base.pm:267 perfSONAR_PS::LSRegistrationDaemon::Base::refresh - Record 'Geant BWCTL Server' is down

 

I have no idea as of how this can be and intend on making another check tomorrow, but I am sure the services of OWAMP and BWCTL are up and running, since I have checked them several times on other occasions.

 

Will continue tomorrow…

 

Best regards,

Ivan

Hi Sowmya, group,

 

Please consult me on an issue with LS registrations similar to the one in applied in the email. As we have replaced 2 of our servers in GEANT with the pS 3.4, we came across an issue with LS registration. One of our boxes is unable to register correctly. The problem continues for almost a week and it seems the old registration still breaks/prevents the new installation to appear properly in the LS (check the applied excerpt). The other server did not have former registration and I suspect that is the reason for being successful now.

 

Please consult me on how to expire/remove old registration and is the current case with conflicting registrations a problem.

Would it be possible to have a procedure to more quickly update/clean-up the LS service.

 

There is another problem I see there. After the installation process, we reviewed the network config and increased the MTU sizes. This update though again has not been indicated on the LS for the failing server. The other did receive an update. Probably this issue is an implication from the general registration issue we experience and the registrations for IP are just matching our previous config (as expected)?

 

I have applied both log and excerpt from LS registration.

 

Best regards,

Ivan

Hi group,

 

I can only add here that the DNS registration appears consistent:

 

[root@sophia-bg ~]# host perfsonar-m1.twaren.net perfsonar-m1.twaren.net has address 211.79.61.148 [root@sophia-bg ~]# host 211.79.61.148 148.61.79.211.in-addr.arpa domain name pointer perfsonar-m1.twaren.net.

[root@sophia-bg ~]#

 

I believe the problem hides here:

Hi,

 

I'm having a problem with a 3.4 install of PerfSonar too.

I downloaded  the Full Install ISO and installed it.

The field "Globally Registered" with "No".

https://211.79.61.148/toolkit/gui/services/

 

Here are the contents of /var/log/httpd/error_log and /var/log/perfsonar/ls_registration_daemon.log files attached below.
