'''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].
* Owing to staff availability the upgrade of Castor to version 2.1.15 is being scheduled to take place in January.
+
<!-- *********************************************************** ----->
* We need to carry out firmware updates on a particular batch of servers - which are in use by Atlas, VMS and LHCb. Will arrange when this can be done. We are also looking to merge the small disk pools in use by Atlas and LHCb into their larger pools.
+
* Following Andrew's return from vacation there has been an update of the FTS3 service.
+
 
<!-- **********************End T1 text************************** ----->

 +
* 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.

* disk only storage
 +
* a GRIDFPT endpoint (a single dns entry)
 +
* an XROOT endpoint (a single dns entry)

Changes to Approved for DUNE (and LZ)
  
https://github.com/gridpp/audit
+
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.
  
For write access, ask Andrew McNab.  
+
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
  
* Changes to CMS resource requirements in 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.
  
See https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
+
Sites with DUNE services need to update using whatever method they employ.
  
Scroll to the Resources table at the bottom and check the new CMS requirements.
+
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.

* There was an EGI ops meeting yesterday - [https://indico.egi.eu/indico/event/4320/ Agenda]. We were asked to review the IPv6 readiness information ([https://wiki.egi.eu/w/index.php?title=IPV6_Assessment see here]). We should perhaps link in the GridPP IPv6 table for updates status.
  
* Downtimes due to the vulnerability CVE-2016-5195: request an A/R recomputation
 
** All the resource centres that were affected by the vulnerability CVE-2016-5195 and that declared a downtime between 2016-10-20 16:00 UTC and 2016-10-31 18:00 UTC are invited to request a recomputation of A/R figures for the days in which the downtime was ongoing.
 
  
* ARGO proposal to use GOCDB as the only source of topology information

Both instances of gridppnagios at Oxford and Lancaster has been decommissioned.
 
 
''' 12th July 2016 '''
 
 
Central ARGO monitoring service  has started from 1st of July. All grid resources are monitored through two Nagios instances
 
 
https://argo-mon.egi.eu/nagios/
 
 
https://argo-mon2.egi.eu/nagios/
 
 
It has same interface as gridppnagios. Alarms from these instances goes to Operational Dashboard
 
 
http://argo.egi.eu/ is a web interface which provides availability/reliability figures and site status. It is equivalent of old myegi interface with some additional services.
 
 
I am planning to decommission both instances of gridppnagios in coming weeks. I have stopped nagios  and httpd on both instances so it will not send tests to grid resources in UK.  I will also decommission storage-monit.physics.ox.ac.uk which was only used for storage replication test. 
 
 
We will keep vo-nagios.physics.ox.ac.uk running until we get a replacement for vo-monitoring.
 
 
 
'''Monday 13th June'''
 
* Active Nagios instance moved to Lancaster
 
 
''' Tuesday 5th April 2016 '''
 
 
Oxford had a scheduled network warning so active nagios instance was moved from Oxford to Lancaster. I am not planning to move it back to Oxford for the time being.
 
 
 
''' Tuesday 26th Jan 2016 '''
 
 
One of the message broker was in downtime for almost three days. Nagios probes picks up a random message broker and failover is not working so a lot of ops jobs hanged for long time. Its a known issue and unlikely to be fixed as SAM Nagios is in its last leg. Monitoring is moving to ARGO and many things are not clear at the moment.
 
 
'''Monday 30th November'''
 
* The SAM/ARGO team has created a [https://wiki.egi.eu/wiki/Service_Level_Target_-_Availability_Reliability document] describing Availability reliability calculation in ARGO tool.

+
** RHUL: The largest problem was related to the SRM. The DPM version was upgraded and it took several weeks to get it working again (13 Jan onwards). Several short-lived occurrences of running out of space on the SRM for non-ATLAS VOs. For around 3 days (15-17 Jan) the site suffered from a DNS configuration error by their site network manager which removed their SRM from the DNS, causing external connections such as tests and transfers to fail. For one day (25 Jan) the site network was down for upgrade to the 10Gb link to JANET. Some unexpected problems occurred extending the interruption from an hour to a day. The link has been successfully commissioned.
+
 
+
** Lancaster: The ASAP metric for Lancaster for January is 97.5 %. There is a particular problem with ATLAS SAM tests which doesn’t affect the site activity in production and analysis and this relates to the path name being too long. A re-calculation has been performed.
+
 
+
** RALPP: Both CMS and LHCb low figures are due to specific CMS jobs overloading the site SRM head node. The jobs should have stopped now.

  • 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.

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.
