* ALICE: Good activity. Preparations for heavy ion reco jobs. At CERN ALICE jobs can request 2 cores and hence have twice the memory but with an impact on efficiency.
 
* ATLAS: new record in parallel running slots: 250k. Some mc15b campaign jobs were requesting an excessive amount of conditions data. Deletion agents: deletion agents were switched off for a few days for operational reasons but once on again struggled to keep up.PRODDISK has been decommissioned on all the Tier2s.
 
* CMS: High loads:~120k parallel jobs. Multi-billion events MC RECO campaign ahead.
 
* LHCb: Very high activity. Several days of failures at SARA when srm was overloaded by a local user. Working on interface to HTCondor-CE.
 
* glexec TF: NTR
 
* HTTP TF: [ https://indico.cern.ch/event/459419 Meeting on 5th November]. Have a working Nagios probe, endpoint lists from the experiments, regular monitoring of the infrastructure (see links on agenda) and a GGUS support unit.
 
* IS evolution: The first draft of the Future Use Cases document is now available for comments. Deadline to provide input is on 24th November. There was a [https://indico.cern.ch/event/454975/attachments/1188757/1724809/ISTF-minutes-12112015.pdf TF meeting on 12th November].

A reminder that there is a weekly [http://www.gridpp.ac.uk/wiki/RAL_Tier1_Experiments_Liaison_Meeting Tier-1 experiment liaison meeting]. Notes from the last meeting [https://www.gridpp.ac.uk/wiki/Tier1_Operations_Report_2015-11-25 here]

'''17 June 2019''' Report for the Experiments Liaison Report (17/06/2019) is [https://www.gridpp.ac.uk/wiki/Tier1_Operations_Report_2019-06-17 here].
* We are investigating why LHCB batch jobs sometimes fail to write results back to Castor (and the sometimes fail to write remotely as well). A recent change has improved, but not fixed, this problem.
+
<!-- *********************************************************** ----->
* We are continuing with the detailed network changes needed to remove our old core switch from the network. We anticipate significant steps on the 8th and 9th December.
+
* As reported last week, the tenders for the next round of Disk and CPU purchases are now out.
+
* We have seen some increased data transfer rates to/from the Tier1. We have a plan to increase the bandwidth on the bypass link (to Tier2s) from 10 to 20 Gbit.
+
* We are implementing a new algorithm for the draining of worker nodes to make space for multi-core jobs. The new version allows "pre-emptable" jobs (ie. jobs that can be stopped at short notice) to run in the job slots until they are needed.
+
* We had failures of three Atlas disk servers over the weekend. It looks like a coincidences as we have found no common cause - at least as yet. All three servers back running now, although temporarily read-only.
+
 
<!-- **********************End T1 text************************** ----->
 
<!-- **********************End T1 text************************** ----->
 +
* Ongoing, we are seeing high outbound packet loss over IPv6.  Central networking performed a firmware update to the border routers but this didn’t resolve the issue.  Plan to move connections to the new border routers in Mid June.  Will do this before trying to debug any further.

 +
* Three certificates were revoked mistakenly on ARGUS on Thursday.  All SAM tests failed until this was fixed the next morning.  Batch farm also did not start any new jobs during this time.  We used this accidental draining to reboot nodes that needed to pick up security patching.
 +
* LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
 +
* Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team.  Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

I've also created a new set of RPMs (each has all LSC, VOMS, and XML for one VO) for all approved VOs. See Approved VOs doc for details, version is 1.9.
 +
 
 +
Sites with DUNE services need to update using whatever method they employ.
 +
 
 +
Special note: Since voms1.fnal.gov changed yesterday, I've updated documentation for that right away. But voms2.fnal.gov remains as it is until 23rd April (3 weeks). I'll update documentation for that when it is closer. Staggering the updates like this gives a time margin, so any particular site can have at least one service properly configured at any time.  But it does mean that two site updates are needed; one now, and one in three weeks. However, since it's sufficient for only one (of the two) voms servers to be configured properly, sites could save effort and wait until (say) 19th April, then update both at once. But I can't dictate what site admins should do. It's your call.

* Few availability tickets on hold

* Lancaster has WebDav ticket on hold which seems to be effect of DOME rollout
  
'''Monday 30th November'''

'''Tuesday 14th August'''
* A quiet week, mostly just cloing alarms for not-in-production services.  There are no open ROD tickets.
+
* A couple of new availability tickets (QMUL and Lancaster), both for well-publicised reasons. Otherwise quiet. AM on shift this week.
 
+
'''Monday 23rd November'''
+
* Still seeing the alarms for systems at QMUL and RHUL that are not in production.
+
* Closed some tickets for the rolling availabilities. Confused by the rolling availability plots. It seems the "rolling average" period was cut back to 20 days.
+
 
+
'''Tuesday 3rd November'''
+
* The long-standing UCL availability alarm went green yesterday on 29th October. We are not sure why!
+
* Quite a lot of activity on the dashboard this week, but only one or two new tickets. 
+
* Tickets: Five for availability / reliability: Sussex, Sheffield, Liverpool, Lancaster and UCL. Two for GLUE2 validation: Liverpool and QMUL. One for the CEs at QMU
+
 
+
'''Tuesday 20th October'''
+
 
+
Lots of bits here and there, but no big pattern. Tickets about CE and storage problems open at several sites. QMUL notable as going on for a while, probably with some kind of configuration problem they're not identifying.

I won't go over all these - but ECDF, BIRMINGHAM and IMPERIAL are still just "assigned". As Ewan did with Oxford's ticket feel free to down the "Priority" for these tickets - these requests aren't urgent at all! A few sites are done already, a few are on holding their tickets till later.

I think that's it for "exciting" tickets - as always let me know if that's not the case.

Not much news on the [https://vo-nagios.physics.ox.ac.uk/nagios/cgi-bin/status.cgi?host=all&servicestatustypes=16&hoststatustypes=15 Other VO nagios] - it's looking pleasantly plain.

Moved Gridppnagios instance back to Oxford from Lancaster. It was kind of double whammy as both sites went down together. Fortunately Oxford site was partially working so we managed to start SAM Nagios at Oxford. Sam tests were unavailable for few hours but no affect on egi availibilty/reliability. Sites can have a look at https://mon.egi.eu/myegi/ss/ for a/r status.

* Following our ops discussion last week, Steve will focus [http://pprc.qmul.ac.uk/~lloyd/gridpp/ his tests] on supporting the GridPP DIRAC area and decommission the other tests.
  
'''Tuesday 29 Sep 2015'''
 
  
Following an air-conditioning problem at machine room in Oxford Tier-2 site on 26 September, gridppnagios(OX) was shut down and gridppnagios(Lancs) became active instance. Oxford site is in downtime until 1st Oct and it may be extended depending on the situation.
 
VO-Nagios was also unavailable for two days but we have started it yesterday as it is running on a VM. VO-nagios is using oxford SE for replication test so it is failing those tests. I am looking to change to some other SE.

  • I got stuck (figuratively) in my machine room last Thursday afternoon so missed it. Agenda. Minutes. Ste was there - any observations?

Tuesday 14th May

  • Next meeting this Thursday.

Tuesday 9th April


Tuesday 26th March

Monday 11th February 2019

  • There was a WLCG ops coordination meeting last Thursday. You can view the meeting notes here.
    • End of CREAM support Dec 2020.
    • Migration from CREAM to be discussed at the EGI conference 6-8 of May in Amsterdam.
    • Operational intelligence discussion (see slides).
    • Experiment updates (see ATLAS discussion on DOMA)
    • WG updates (few).




Tier-1 - Status Page

17 June 2019 Report for the Experiments Liaison Report (17/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.

11 June 2019 Report for the Experiments Liaison Report (10/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.
  • Three certificates were revoked mistakenly on ARGUS on Thursday. All SAM tests failed until this was fixed the next morning. Batch farm also did not start any new jobs during this time. We used this accidental draining to reboot nodes that needed to pick up security patching.
  • LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
  • Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team. Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

  • CEPH workshop at CERN report

Wed 02 Oct

  • Safe to upgrade to DPM 1.13 but make sure the BDII is working if you support DIRAC
  • Roadmap for xroot and http TPC for RAL FTS(es)

Wed 25 Sept

  • Storage support for IRIS VOs?

Wed 18 Sept

  • Report from yesterday's Rucio Face Meeting at Coseners
  • Suggestions for following up from yesterday's CEPH day hosted by CERN

Wed 11 Sept

  • Storage related stuff at the FNAL (pre-)GDBs
  • DOME upgrade tickets for non-DOME DPM sites

Wed 04 Sept

  • Banning in SSC not entirely successful in non-DOME DPM, and end of support is nigh; tickets to upgrade will go out shortly.
  • Storage-and-data-management-wise, GridPP43 was interesting although no-one volunteered to install the next CEPH.

Monday 14th November

  • Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB.

Monday 26th September

  • A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.
Documentation - KeyDocs

Tue 9th July 2019

LHCb has added this to their requirements:

Sites not having an SRM installation must provide:

Tue 16th April 2019

Minor change to LHCB requirements in Approved VOs:

  • Sites having migrated to the Centos7 (including "Cern Centos7") operating system or later versions are requested to provide support for singularity containers.

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs#VO_Resource_Requirements

Tue 2nd April 2019

Changes to Approved for DUNE (and LZ)

There is a new "Approved VOs" document showing new settings for DUNE. And, since both LZ's voms servers now show up in the EGI Portal, I've removed the (now spurious) entry for voms.hep.wisc.edu that was formerly being inserted by hand.

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs

I've also created a new set of RPMs (each has all LSC, VOMS, and XML for one VO) for all approved VOs. See Approved VOs doc for details, version is 1.9.

Sites with DUNE services need to update using whatever method they employ.

Special note: Since voms1.fnal.gov changed yesterday, I've updated documentation for that right away. But voms2.fnal.gov remains as it is until 23rd April (3 weeks). I'll update documentation for that when it is closer. Staggering the updates like this gives a time margin, so any particular site can have at least one service properly configured at any time. But it does mean that two site updates are needed; one now, and one in three weeks. However, since it's sufficient for only one (of the two) voms servers to be configured properly, sites could save effort and wait until (say) 19th April, then update both at once. But I can't dictate what site admins should do. It's your call.
