Attending: Daniel, Elena, Jens (chair+mins), Lukasz, Winnie, Pete, Steve, John B, Robert, John H, Ewan, Brian, Sam, David, Gareth, Raul, Catalin Operational issues: ATLAS GFAL issues (Brian). lcg-utils being replaced. Some sites never worked for the old GFAL. With CASTOR a TURL can be used at most once, so if you do something other than transfer then the subsequent transfer is likely to fail (didn't someone test this?!!?) Should work in FTS but not RAL WNs accessing CASTOR with GFAL. How do fall backs fall back? Specifically, what is the "nearest copy"? HTTPD federations try geographically nearest. ATLAS and CMS do something similar with FAX and AAA. DIRAC issues (not to be confused with anything else called DIRAC etc etc) Cardiff (aka LIGO) problems may be with IC disk? Could try someone else's disk? Worth following up on the follow ups; we can invite Paul back to chat with us later. LIGO currently use SouthGrid as "their" VO. There will also be a LZ VO at Edinburgh And ILDG (http://www.usqcd.org/ildg/) - Sam following up. The GridPP support list has been set up by Jeremy. Currently both Jeremy and Jens are admins and we took the opportunity to invite people to be invited: Jens will sign up the following volunteers: David, Catalin, Pete, Gareth, John H, Lukasz, Raul, Robert, Steve, Elena Others have already joined, or will presumably be joining in the fullness of time. There was a question about the list as it could not be searched for (well it could but the search returned nothing). We didn't think we'd twiddle the list settings without checking with Jeremy as he may have had some good reasons for setting the settings the way they were set, or maybe they were just the defaults. Catalin gave a summary of his impressions of the EGI conference, having attended all week. * Mostly followed cloud activities and CVMFS * Data management included fedcloud and open data cloud * Open data looked at categorisation and transfers between sites * Cyfronet open data, used and reused * EGI to open and share data * CDMI demo, based on SNIA 1.02, with EGI fedcloud * "Competence centres" for A&H, life, bio, and structural bio Ewan Mac Mahon: (27/05/2015 10:09:37) AIUI FAX fails over to whoever's got the file. It's not neccessarily failing up the tree. It's magic. It asks the next redirector to redirect it, but the expectation is that it will get a steer, not a file. Plus I believe our redirector (the 'UK' one) is at CERN rather than RAL anyway. Paige Winslowe Lacesso: (10:11 AM) Is this implicitly atlas-only? Ewan Mac Mahon: (10:12 AM) It's possible that if RAL happens to have the file then the CERN based FAX redirector might redirect a request back down to RAL, but it's equally as likely that it would redirect it somewhere else. FAX is ATLAS' xroot redirection thing, AAA is CMS' xroot redirection thing, they have much in common and some differences. Dirac does have some degree of web interface mind you. Don't know how much it covers the storage side, but the job management interface is quite nice. Paige Winslowe Lacesso: (10:33 AM) I noticed that too. Tom Whyntie: (10:33 AM) Ha! Ewan Mac Mahon: (10:35 AM) And probably secret archives too. Which is bad, Catalin Condurache: (10:35 AM) yes Peter Gronbech: (10:36 AM) yes please Ewan Mac Mahon: (10:36 AM) And it's here: https://www.jiscmail.ac.uk/cgi-bin/webadmin?A0=GRIDPP-SUPPORT if anyone would like to sign up/otherwise look at it in the normal manner. Paige Winslowe Lacesso: (10:37 AM) Erm, what was the question? I already am I thot?! I signed up to Gridpp-Support yesterday & got the ack email.... In looking at the page it says I'm a Moderator in fact. Ewan Mac Mahon: (10:38 AM) Ah, right-o. There is also gridpp-users, which is a whole other thing. raul: (10:38 AM) yes please Ewan Mac Mahon: (10:39 AM) It's basically the "Tier 1 network outage announcements" list, which is apparently very important to some people. Elena Korolkova: (10:40 AM) I have problem with a sound when Jens read a list of people. Just to confirm: please, include me to the list. Thanks Jens Jensen: (10:41 AM) OK Elena Korolkova: (10:41 AM) Thanks Jens Jensen: (10:45 AM) They've said that for a while :-) theubercloud.com Samuel Cadellin Skipsey: (10:50 AM) I am sad that they aren't spelling uber with the umlaut. Ewan Mac Mahon: (10:53 AM) Slough.
