Grid Operator Hand Over on Duty

  Primary Team Secondary Team
From ROC Russia ROC UK/I

Sites Considered For Suspension
  • Vera, once again reporting from a train, thought that since the IN-DAE-VECC-EUINDIAGRID site had not responded for a few weeks, it was worth mentioning in the hand-over log. Shu-Ting followed it up a bit, and discovered that there was another cause.
  • INFN-FERRARA has been in scheduled downtime since the end of January, but the situation is understood.

PPS Reports and Issues

  • CERN Prod is now running two CREAM-CEs for ALICE production. The EMT is tracking a series of patches for the 4th April.
Antonio tried to get the BDII 5 patch accelerated in the EMT, but they had other priorities. However, they were happy to have volunteers to test it (please contact Antonio using pps-support AT cern.ch).

  • gLite 3.1 PPS Update 45:
    • fixes FTS job submission problem (invalidated proxy problem).
    • new VOMS server certificates included.

gLite Release News

  • gLite 3.1 Update 42 to production in preparation scheduled for 23-MAR-2009
    • adds a dependency on "which"
    • includes VDT 1.6.1 Release 9 which fixes a Globus bug (affects most m/w services)
    • includes new version of VOMS certificates

  • gLite 3.2 Update 01 to production in preparation scheduled for 30-MAR-2009
    • new SL5 WNs
    • signed repository for RPMs

Antonio commented that the approach is for quick, and well-focused releases (with roll-back facility) rather than big bang ones.

EGEE Items From ROC Reports

  • CE ROC reported a problem with GStat and installed capacity. Steve commented that having more free CPUs than total CPUs was “a wonderful position to be in”, but mentioned that the GStat developers were at CERN this week and that he hoped that the problem would be fixed soon.
  • France had a more severe outage than anticipated last Tuesday, but they were back to normal on the same day.

Grid Service Interventions

  • There will be significant disruption at CERN on Thursday 19th March
    • As of: 5:00AM to 8:00AM DNS, DHCP, DBs, EDH, NICE, email, web, AFS, lxplus will be affected.
    • As of: 8:00AM to 13:00 LCG disks, tapes and CPUS will be affected.

Request to sites, ROCs etc. to report any collateral damage (spot the things that break due to dependencies when they shouldn’t). Jeremy: The point of raising it today is to make sure that everyone is looking out for things that break and each region/country is keeping an ordered list that can be combined with others and referenced.

GridMap Update

  • For those who missed the announcement, a new and improved version of GridMap is available. See the agenda page for the list of new features. Max.Boehm AT eds.com will accept comments.

WLCG Service Coordination

ATLAS Service

  • Absent

ALICE Service

  • Absent

CMS Service

  • [Pointer to the daily WLCG reports is not very helpful. A summary for this meeting would be appreciated - John]

LHCb Service

  • Roberto mentioned the LHCb show stopper due to a WMS outage possibly related to the “mega-patch”. Restarting WMS every two minutes is a terrible workaround.
  • He asked that the CIC portal provides a virtual memory field in the VO card (only physical memory available now). [The obvious question is "did he submit a GGUS ticket?" - John]
  • CNAF STORM issue needs escalating (CNAF not responding to GGUS ticket). Maria: did you click on the escalate button? A FAQ is available on the GGUS homepage about escalation policy.

Harry re-iterated, or clarified as the case may be, that the Castor and FTS services at CERN would be down on the 19th until 18:00.

OSG Items

Rob covered four escalated tickets:
  • 1 will take about a month to solve
  • 46646 & 46647 seem to be duplicates but awaiting customer feedback
  • 46682 was resolved on 11th.
Maria: why can’t progress fields be updated? Does Guenter need to debug something? For tickets awaiting customer feedback, should they be set to resolved? Maria was asked to take the issue off-line with Rob & Guenter.

None,... and then suddenly, Helene: Downtime from GOCDB on Wednesday morning for new release which puts CIC-portal at risk. She will send a broadcast.
