New page<div>ScotGrid Technical Meeting 12 June 2013 - Sam S (minutes) Andy W Gareth R David C Ewan S Mark M (comfy chair) - ECDF Andy: nothing exciting. Only thing we can think of is that we got a ticket from Andrew McNab - re publishing security. It turned out that this was the security patch for the blah parser also resulting in mistakenly regressing another piece of config. Operationally, running fairly smoothly, but still restricted to the SL5 set for ATLAS. Seems to be no momentum from ATLAS to move to SL6. - Glasgow Mark: the aircon's "fixed" for 243d (now had almost every single part of it replaced), and seems to have stuck as fixed for now. Getting some additional test equipment in to do OpenFlow testing work for Extreme. Plan for delivery and upgrade of power and aircon underway. Should have a decision made on a tender supplier by the end of July. Dave: not much to say. Were at HEPSYSMAN. A good meeting, security training was effective and useful. Since then, tidying up monitoring, looking at some disk housekeeping with our 3ware cards. Monitor - securing, and then going to writeup notes and post them up. Feeling that using stated etc for system metrics, rather than individual ones, to prevent runaway complexity. Next on list is that kind of stuff, and dashboards, followed by SNMP. Sam: working with DDN on DPM test work, providing local access to Tier2 storage via xrootd (direct I/O). Gareth: this week has mostly been ticket wrangling. It does look like we finally have our IPv6 gridftp mesh test box working (thanks to public reverse DNS working for IPv6) - Durham Ewan: long term aircon issues for the last 6 weeks. Last Wed: supposed to come and fit a new controller card for an AHU - actually got done on Monday. A condenser was also replaced. Temperature now appears to be stable. Mike is on with SL6 UIs for our local users. Had some problems with authentication, but think they are resolved. Starting to play with SLURM for our desktop users. Plans for SL6 on grid cluster - waiting on how the SL6 UIs work. It was asked if Durham could send an attendee to the Ops meeting on Tuesday. AOB CHEP funding was discussed. There is still a debate about the funding situation (especially regarding the fraction of funding). - Chat Log 11:03:59] Mark Mitchell joined [11:02:14] David Crooks Hi Ewan [11:02:18] Ewan Steele hi [11:02:21] David Crooks Just getting set up here [11:02:29] Ewan Steele ok [11:02:32] David Crooks How are things?

New page<div>ScotGrid Technical Meeting minutes 15 May 2013 -- Mark Mitchell (chair) Sam S (minutes) David C Gareth R Ewan S Mike J Andy W - Durham Mike: Making good progress SL6. Ewan on monitoring, prototyped now, can be rolled out without much hassle. Ticked Biomed and had no response for a week. Have closed ticket as unsolved with threat of withdrawn support, will see if they reopen it. Aircon failure on Friday. Had to dump WNs to reduce air temp increase. Turned on on Monday. EMI3 UI up and running. LHCb ticket 92590: Mark looked at update, and Vladimir suggested making a LHCb pilot mapping. Mike believes this has already been done. Some discussion about the mapping (syslog shows that *some* LHCb DNs are definitely being mapped to users). The issue is diagnosed as a missing pilot role mapping for LHCb. Gareth shared Glasgow config to help Durham add the right mappings. - Edinburgh Andy: Nothing much to report. Looking at SL6 move still, got SL6 CE accepting jobs, one of the test queues is now an SL6 test queue. Seems to work, but with a few errors (which seem to be related to the WN tarball). Unfortunately, the SL6 tarball is only in test - installed yesterday, and needs a few tweaks. Should be going soon. Still battling over internal network restrictions, but ongoing. Squid monitoring change - needed to get the site firewall adjusted, so needs a ticket to progress internally. Ticket against ECDF, Wahid aware and will resolve. - Glasgow Mark: little happened here. Aircon unit once again rebuilt to prevent it dying whenever it is even slightly hot. Mark featured in an article in TechWorld on Extreme networking. Stuart is leaving in the next several months, we'll be replacing him via a hiring process. Date probably late July. Trying to put together a grant submission with GEANT. Pile production: even though we're not enabled for high memory jobs, PaNDA still assigned a few hundred 4G jobs to us (which then spun in PanDA without being able to actually be picked up by the pilots) Dave: has been developing more Graphite monitoring. Will be giving a talk at HepSysMan on this. New MICE user - MICE don't have a fully developed experiment software policy, so we've been making his software work locally at Glasgow. - AOB Scotgrid F2F will happen August 21st 2013 in Durham. - Chat Log - 10:59:23] Gareth Roy Yup [10:59:46] Mark Mitchell I can hear you [10:59:52] Mark Mitchell Hooray [11:00:13] Mark Mitchell Give it 5 mins for Edinburgh [11:00:41] Gareth Roy Nope [11:00:50] Gareth Roy or if so it's really quiet [11:03:07] Andrew Washbrook sorry - other meeting was running a little late [11:05:11] Mark Mitchell wages will be docked Washbrook.
