SSB test changes

• Move to rucio

– Went according to plan – All endpoints not having rucio enabled N2N turned red – Now situation much more stable as proved by very rare “instant” mails to the cloud supports lists.

Side note: now “Delays” and “Monitoring” tests split off in a new “FAX specialists” view.

SSB test changes

• “locate -r” issue

– We noticed that sometimes the “direct” test was failing but only for the file being tested and all other files were working. – Reason was found by Andy: in another “delay” test I was doing a “locate –r” which does a file lookup after dropping it from cmsd cache. That triggers a bug. – The bug will be fixed by Andy and in a meanwhile SSB uses different files for these two tests.

• X509 check

– Before was using my certificate without VO ATLAS – That was not a good test as both DPM and dCache don’t check for VO but DN. – Thanks to Wei, I have a new SLAC VO cert. – Now all the working endpoint do require ATLAS cert to read the data.

Deployment

Old Xroot version Not setting sitename Not using f-stream Missing the new N2N GLRD – 3.2.7 JINR Oxford CERN-PROD – 3.2.7 Wuppertal Liverpool RAL – 3.2.4 Lancaster Sheffield Geogrid – 3.2.7 Prague Wuppertal – 3.2.7 Wuppertal in2p3-lpsc – 3.2.7 IN2P3-LPSC in2p3-lapp – 3.2.7 GRIF-LAL, GRIF-IRFU, GRIF-LPNHE in2p3-cppm – 3.2.7 grif-lpnhe – 3.3.2 grif-lal - 3.3.2 grif-irfu – 3.2.7

Upgrades are coming (slowly) and are often partial

Matevz will implement sending this information to collector (two weeks) I’ll make the code to check for this

Operations

– Should we de-activate part of the FR cloud? Currently no mainland France endpoint works. – LFC-free N2N for dCache exists and has been deployed. – LFC-free N2N for other sites is in testing – In process of adding Beijing endpoint

• The only remaining issue is opening the ports.

– All of the test datasets in place (both SSB and FDR) – Looking for a solution to a problem seen at 3 IT and one UK endpoint:

Xrd: CheckErrorStatus: Server [t2-dpm-01.na.infn.it:1094] declared: Secgsi: ErrParseBuffer: unknown CA: cannot verify client credentials: kXGC_certreq(error code: 3010)

Smaller issues

• localSetupFAX

– Should we move to xrootd client 3.3.6? – For the second time we had a temporary issue with a freeGeoIP service. Will look at the possibility of hosting it at MWT2.

• A large speed up of pandamon fax failover page.

Still some way to go.

Plans

• Push on deployment
• Continue USA cloud stress testing
• Further tutorial development
