| General updates
|
Tuesday 29th September
- Nagios was (and therefore the regional dashboard has) affected by a weekend A/C outage at Oxford.
- Steve J reports on: Condor libglobus_common problems
- There was an EGI OMB on 24th September. Agenda.
- Notes from the Monday biweekly WLCG ops meeting are available for anyone who is interested in the latest ops news.
- On the topic 'Perfsonar Bandwidth checks not running' Duncan reported a move to a full WLCG mesh.
- Tom would appreciate feedback on the GridPP website v2.
- Steve Lloyd has setup a metrics page as a basis for allocating T2 hardware funding. This just uses total Disk and total Elapsed and/or CPU time. In the PMB yesterday it was agreed that Elapsed time would be used, but the results of various combinations will be watched and assessed over the coming months. One overriding reason for using Elapsed time is that CPU is not provided by all cloud implementations.
-
Tuesday 22nd September
- Monday's WLCG weekly ops meeting minutes are available.
- There is an EGI Operations Management Board this Thursday. Do we have any items to raise?
- Several observations recently of FTS3 at RAL being overloaded.
- Federico raised: anomalous CPU usage for DIRAC ilc jobs.
- Looking at supporting DEAP3600 (RHUL, RAL and Sussex).
Tuesday 15th September
Tuesday 1st September
- From October/November, the EGI ops VO monitoring will be performed using RFC proxies, as opposed to legacy proxies.
- There will be a new filter for the critical profile for ATLAS WLCG SAM tests so that only production endpoints will be tested and taken into account for site availability metrics. This will be available from the SAM3 interface.
- CNAF: Due to a fire causing problems with one electrical supply line that happened last Thursday, the computing centre is running at lower capacity (around 30% less of the pledged capacity).
- Machine job features testing has hit a big according to Raul!
- The HNSciCloud PCP pilot proposal successful submission (refer to Andrew Sansum's talk at GridPP34 if you forget what this means!). The project intends to procure commercial cloud resources for FY17 and FY18. We will contribute 75K euro towards this activity and the EU will then top up to 250K euro.
- There was an EGI Operations Management Board last Thursday. There are no summary notes yet, but please take a look at the agenda and linked talks (may be worth skimming them at the ops meeting).
- There was a quick request/reminder for sites to please update their IPv6 entries in the GridPP wiki.
- RAL is closed on Monday and Tuesday of this week!
Tuesday 24th August

| WLCG Operations Coordination - Agendas
|
Tuesday 22nd September
- There was an ops coordination meeting last Thursday: 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 Sites; Experiments.
Tuesday 15th September
- There was a middleware readiness meeting on 16th September.
- The new DPM version is being tested via the ATLAS workflow by the Edinburgh Volunteer site.
- Many new sites showed interest to participate in MW Readiness testing with CentOS7. It is useful to anticipate the MW behaviour in the event of new HW purchase. DPM validation on CentOS/SL7 is already ongoing at Glasgow.
- ATLAS and CMS are asked to declare whether the xrootd 4 monitoring plugin is important for them or not. As it is now, it doesn't work with dCache v. 2.13.8
- Despite the fact that FTS3 runs at very few sites we decided to test it for Readiness. In this context, ATLAS and CMS are asked to use the FTS3 pilot in their transfer test workflows
- PIC successfully tested dCache v.2.13.8 for CMS.
- CNAF has obtained Indigo-DataCloud effort to strengthen the ARGUS development team. The ARGUS collaboration will meet again early October. The problems faced at CERN with a CMS VOBOX are being investigated in ticket GGUS:116092.
- The next MW Readiness WG vidyo meeting will take place on Wednesday 28 October at 4pm CET.

Tuesday 29th September
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- The problems with the production FTS service have been resolved. A workaround to the memory leak introduced with the
new version has been supplied. This, along with a reduction in the numbers of transfers queued, has enabled the service to return to
normal operation.
- - The second step in the upgrade of the Castor Oracle databases to version 11.2.0.4 took place last Tuesday. This was the upgrade of
the "Neptune" standby database and the re-establishment of the Dataguard link. ("Neptune" hosts the Atlas and GEN instance
stagers.). The next step in this upgrade is the upgrade of the "Pluto" database which hosts the Nameserver as well as the CMS & LHCb
stager databases. This will require all of Castor to be down for the day and is scheduled for the 6th October.
- We have announced an 'at risk' for tomorrow morning (Wednesday 30th Sep.) as the Tier1's link into the RAL core network is upgraded to 40Gb. This will take place between 07:00 and 08:30.

| On-duty - Dashboard ROD rota
|
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.
Tuesday 1st September
- Gordon was on shift.
- Another very quiet week with no new tickets. We have two open ROD tickets, both of which are for A/R; one is against Cambridge, and the other is the now 53-day-old ticket at UCL.
- Next up.... Kashif again (thanks Kashif!)
Monday 24th August
- Kashif on shift.
- There were quite a few alarms throughout the week and many tickets were opened. All of the tickets were fixed within time limit.
- The certificate of the Argus server at sheffield expired but Elena got a new certificate quickly.
- Cambridge and UCL have low availibilty tickets and not much can be done about it except waiting for availibilty to reach 90%.

Tuesday 15th September
Tuesday 12th May
- MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy.
Tuesday 17th March
- Daniela has updated the [ https://www.gridpp.ac.uk/wiki/Staged_rollout_emi3 EMI-3 testing table]. Please check it is correct for your site. We want a clear view of where we are contributing.
- There is a middleware readiness meeting this Wednesday. Would be good if a few site representatives joined.
- Machine job features solution testing. Fed back that we will only commence tests if more documentation made available. This stops the HTC solution until after CHEP. Is there interest in testing other batch systems? Raul mentioned SLURM. There is also SGE and Torque.

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
