The transition to SL6MAIN REFERENCE
CURRENTLY REPORTED
last meeting(s)
-
All sites - deploy by end of
May, June - Shuwei validating on SL6.4; believes ready to go. BNL_PROD will be modified - in next few days 20 nodes will be converted. Then the full set of nodes.
- Doug - provide a link from the SIT page. Notes prun does compilation.
- Main thing to consider is whether you upgrade all at once, or rolling.
- BNL will be migrated by the COB today! Will be back online tonight. BNL did the rolling update.
- Look at AGIS - changing panda queues much easier
- Are the new queue names handled reporting? If they are members of same Resource Group.
- What about $APP? Needs a separate grid3-locations file. But the new system doesn't use it any longer.
-
Schedule:
-
BNL
- June 10 - AGLT2 - will do rolling
- MWT2 - still a problem with validations; could start next week
- SLAC - week of June 10
- NET2 - all at once. Week of June 17
- UTA - all at once. June 24. Lots of dependencies - new hardware, network. A multi-day outage is probably okay.
- OU - all at once. Rocks versus Puppet decision. After July 5.
-
BNL
- Goal: Majority of sites supporting the new client by end of June. May need to negotiate continued support

AGLT2: 1/3 of worker nodes were converted; ran into a CVMFS cache size config issue, but otherwise things are going well. The OSG app is owned by usatlas2, but validation jobs are now production jobs. Doing rolling upgrade. They are using the newest cvmfs release. n.b. change in cache location. Expect to be finished next week.
- Fully migrated.
-
NET2: HU first, then BU. At HU - did big bang upgrade; ready for Alessandro to do validation. Ran into problem with host cert. 2.1.11 is production. One machine at BU. Hope to have this done in two weeks. BU team working on HPC center at Holyoke.
- HU done
- BU: GPFS testing is complete. Top priority. Augustine will be working on this non-stop.

SWT2 (UTA)
- End of week will be migrated. OU will be coming on Monday to go over the Rocks6.

SWT2 (OU)
- Will be visiting on Monday. OSCER queues doing validation now.

- Some validation jobs are failing, and also with Analysis queue
- Writing to CVMFS?
- No response from Alessandro.
Updates from the Tier 3 taskforce?
last meeting- Report is due by July
- Doing testing of Tier 3 scenarios using grid or cloud resources
- Working with AGLT2 as a test queue.
- Managed to get surveys from every Tier 3 site. Writing assignments will be setup for the final report.
- Half the community does not have resources on their campus.
- Solve the data handling problem to local resources; as fully supported DDM endpoint. gridftp-only endpoints were never fully supported.
- Survey report will be available in two weeks
this meeting
Glexec
- See https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsMinutes130620. The plan foresees making the gLExec SAM tests critical starting from October; experience shows that setting up gLExec and passing the tests is not difficult, it is well documented and it does not risk affecting any production workflow.

Claim is these instructions work:
https://www.opensciencegrid.org/bin/view/Documentation/Release3/InstallGlexec
We will need a volunteer to test this out and give feeback to the group.
- AGLT2 can start looking at it in a couple of weeks
- NET2 would like to help
- Torre: notes discussion in ADC management, preparing statement to the effect that this would be optional for sites.

- IU - plan is to decide friday whether whether we need to bypass the brocade, access Juniper directly to peer with LHCONE. Fred is working closely with the engineers.
- Shawn - Mike O'Conner has been putting together a document with best practices. Will have examples on how to route specific subnets that are announced on LHCONE.
- Three configurations: 1. PBR (policy based routing). 2. Providing a dedicated routing instance. Virtual router for LHCONE subnets. 3) Physical routers for gateway for LHCONE subnets.
- NET2: have not been pushing it, but will get ball rolling again - will contact Mike O'Conner and provide feedback.
