'''Tuesday 26th March'''
 +
* For information, there was an Ops meeting on the 7th: https://twiki.cern.ch/twiki/bin/viewauth/LCG/WLCGOpsMinutes190307 (I think we might have dicussed this one).
 +

'''Next Meeting is scheduled for Thursday 22nd October'''
 
  
'''Tuesday 6th October'''
 
* There was a WLCG ops coordination meeting last week. [https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsMinutes151001 Minutes]. [https://indico.cern.ch/event/393617/ Agenda] (which has John Gordon's accounting slides).
 
* The highlights:
 
** dCache sites should install the latest fix for SRM solving a vulnerability
 
** All sites hosting a regional or local site xrootd should updgrade it at least to version 4.1.1
 
** CMS DPM sites should consider upgrading dpm-xrootd to version 3.5.5 now (from epel-testing) or after mid October (from epel-stable) to fix a problem affecting AAA
 
** Tier-1 sites should do their best to avoid scheduling OUTAGE downtimes at the same time as other Tier-1's supporting common LHC VOs. A calendar will be linked in the minutes of the 3 o'clock operations meeting to easily find out if there are already downtimes at a given date
 
** The multicore accounting for WLCG is now correct for the 99.5% of the CPU time, with the few remaining issues being addressed. Corrected historical accounting data is expected to be available from the production portal by the end of the month
 
** All LHCb sites will soon be asked to deploy the "machine features" functionality
 
  
'''Tuesday 22nd September'''
 
* There was an ops coordination meeting last Thursday: [https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsMinutes150917 Minutes].
 
* Highlights:
 
**  All 4 experiments have now an agreed workflow with the T0 for tickets that should be handled by the experiment supporters and were accidentally assigned to the T0 service managers.
 
**  A new FTS3 bug fixing release 3.3.1 is now available.
 
**  A globus lib issue is causing problems with FTS3 for sites running IPv6.
 
** The rogue Glasgow configuration management tool replacing the current configuration for VOMS with the old one was picked up and unfortunately discussed as though sites had not got the message about using the new VOMS.
 
**  No network problems experienced with the transatlantic link despite 3 out of 4 cables being unavailable.
 
**  T0 experts are investigating the slow WN performance reported by LHCb and others.
 
**  A group of experts at CERN and CMS investigate ARGUS authentication problems affecting CMS VOBOXes.
 
**  T1 & T2 sites please observe the actions requested by ATLAS and CMS (also on the WLCG Operations portal).
 
* Actions for [https://wlcg-ops.web.cern.ch/sys-admins/tasks Sites]; [https://wlcg-ops.web.cern.ch/experiments/tasks Experiments].
 
  
'''Tuesday 15th September'''
 
* The [https://indico.cern.ch/event/393616/ next WLCG ops coordination meeting is this Thursday 17th September]. Are there any Tier-2 issues we wish to raise? Minutes will appear [https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsMinutes150917 here].

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_2015-10-14 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].
* The final step in the upgrade of the Castor Oracle databases to version 11.2.0.4 took place successfully last Wednesday.
+
<!-- *********************************************************** ----->
* We had seen very high load on Atlas Tape. Last week the number of disk servers in the cache in front of Atlas Tape was doubled. Load (and performance) has been better since, although Atlas also throttled back writes at that time.
+
* We had three disk server problems Friday/Saturday/Sunday (Two Atlas disk servers, One LHCb).
+
* A configuration change has been made on both our "production" and "test" FTS3 services to fix that ATLAS/rucio stalled connections problem.
+
* We are investigating why LHCB batch jobs sometimes fail to write results back to Castor (and the sometimes fail to write remotely as well).
+
* As reported this last couple of weeks - we did have a problem with glexec for the worker nodes over a weekend. We are trying to understand why this problem was not seen during the testing and roll-out of the new worker node configuration.
+
 
<!-- **********************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.

'''Tuesday 22nd September'''
 
* Slight delay for Sheffield but overall okay - although there is a gap between today's date and the most recent update for all sites. Perhaps an APEL delay.
 
  
'''Monday 20th July'''
+
'''Tuesday 30th January'''

LHCb has added this to their requirements:
  
'''Tuesday 29nd September'''
+
Sites not having an SRM installation must provide:
Steve J: problems with voms server at fnal, voms.fnal.gov, have been detected; I will resolve them soon and may issue an update to Approved VOs, alerting sites with TB_SUPPORT should that occur. Approved VOs potentially affected are CDF, DZERO, LSST. Please do not act act yet.
+
  
'''Tuesday 22nd September'''
+
* disk only storage
* Steve J is going to undertake some GridPP/documentation usability testing.  
+
* a GRIDFPT endpoint (a single dns entry)
 +
* an XROOT endpoint (a single dns entry)
 +
* a way to do the accounting (preferably following the WLCG TF standard: https://twiki.cern.ch/twiki/bin/view/LCG/StorageSpaceAccounting)

+
Minor change to LHCB requirements in Approved VOs:
* Ewan: /cvmfs/gridpp-vo help ... there's a lot of historical stuff on the GridPP wiki that makes it look a lot more complicated than it is now. We really should have a bit of a clear out at some point.
+
 
 +
* Sites having migrated to the Centos7 (including "Cern Centos7") operating system or  later versions are requested to provide support for singularity containers.

 +
 
 +
'''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.

 +
* Birmingham decommissioning of SRM and BDII still going on so tickets are on hold.
 +
* Few availability tickets on hold
 +
* Lancaster has WebDav ticket on hold which seems to be effect of DOME rollout
  
'''Tuesday 20th October'''
+
'''Tuesday 14th August'''
 +
* A couple of new availability tickets (QMUL and Lancaster), both for well-publicised reasons. Otherwise quiet. AM on shift this week.
  
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.
 
 
 
'''Tuesday 6th October'''
 
* With the exception of the dashboard getting really confused early in the week as the Nagios instances at Oxford and Lancaster came and went, it's been a fairly quiet week.  There are four outstanding tickets:
 
** Three for availability / reliabaility (Sussex, Liverpool and Lancaster).
 
** One at Bristol for a GridFTP transfer problem.
 
 
'''Tuesday 15th September'''
 
* Generally quiet. QMUL have some grumblyness with the CEs. However, I understand much of this is caused by the batch farm being busy. There are low-availability tickets 'on hold' for Liverpool and UCL.

27 Open UK Tickets this week. Not many seem all that exciting though.
 
  
The line to all the UK [http://tinyurl.com/nwgrnys '''tickets'''].
+
32 Open Tickets this week, which is an in depth a look as I've been able to take.
 
+
The few (two) tickets that really caught my eye are:
+
 
+
'''QMUL'''<br />
+
[https://ggus.eu/?mode=ticket_info&ticket_id=117151 117151] (23/10)<br />
+
This ticket is quite interesting, mainly for Dan schooling the submitter. QM received a ticket complaining that their jumbo frames were breaking stuff - it doesn't looking like the problem is at QM though. Naught wrong with the ticket handling. Waiting for reply (23/10)
+
 
+
'''BRISTOL'''<br />
+
[https://ggus.eu/?mode=ticket_info&ticket_id=117065 117065] (20/10)<br />
+
Bristol have a CMS glexec error ticket that looks very similar to an existing one ([https://ggus.eu/?mode=ticket_info&ticket_id=116683 116683]), which is in turn spookily similar to a ticket being worked on by the Bristol admins ([https://ggus.eu/?mode=ticket_info&ticket_id=116775 116775]). At the very least I would say that if the two problems are different one would likely obfuscate the other. Is this a case of over-keen shifters submitting tickets without checking? I'd be tempted to close one or both of [https://ggus.eu/?mode=ticket_info&ticket_id=116683 116683] and this one ([https://ggus.eu/?mode=ticket_info&ticket_id=117065 117065]). Tell them I said it was okay to[1]. In progress (21/10)
+
 
+
[1] It probably is okay to.
+
 
+
There are also 4 availability tickets, all On Hold waiting for 30 days or so to pass.
+
 
+
[https://vo-nagios.physics.ox.ac.uk/nagios/cgi-bin/status.cgi?host=all&servicestatustypes=16&hoststatustypes=15 '''Other VO Nagios'''] looks clean at time of writing.

+
* The WLCG dashboard is available here: http://dashboard.cern.ch/.  
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.  
+
* Please review the results on [http://pprc.qmul.ac.uk/~lloyd/gridpp/ Steve's test pages].
 
+
'''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.    
+
 
+
'''Tuesday 09 June 2015'''
+
*ARC CEs were failing nagios test becuase of non-availability of egi repository. Nagios test compare CA version from EGI repo. It started on 5th June and one of the IP addresses behind webserver was not responding. Problem went away in approximately  3 hours. The same problem started again on 6th June. Finally it was fixed on 8th June. No reason was given in any of the ticket opened regarding this outage. 
+
 
+
'''Tuesday 17th February'''
+
* Another period where message brokers were temporarily unavailable seen yesterday. Any news on the last follow-up?
+
  
'''Tuesday 27th January'''
+
'''Tuesday 18th July'''
* Unscheduled outage of the EGI message broker (GRNET) caused a short-lived disruption to GridPP site monitoring (jobs failed) last Thursday 22nd January. Suspect BDII caching meant no immediate failover to stomp://mq.cro-ngi.hr:6163/ from stomp://mq.afroditi.hellasgrid.gr:6163/

* 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.

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.

  • 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.

  • 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.
