- Next LHCOPN and LHCONE meeting: Helsinki (FI) 19-20 of September 2016: Agenda.
Tuesday 22nd March
Tuesday 8th December
- Given the recent network issues and role of GridPP DIRAC, there are plans to have a slave DNS for gridpp.ac.uk at Imperial and hopefully the T1 too. Andrew will seek an update to the whois records and name servers once the other host sites are confirmed.
- Looking at the network problems this week will be of interest. Duncan supplied this link and Ewan the one for the dual stack instance.

Tickets

Friday 19th August 2016, 11.30 BST
29 Open UK tickets today.
Link to all the UK Tickets.
VOMS servers
123333 (9/8)
After the blip with the VOMS servers last week Daniela opened this ticket - it looks like the problem is fixed now, and this ticket can be closed. Assigned (17/8)
BRISTOL
123419 (16/8)
A low availability ticket for Bristol, which has Winnie a little confused as the "created_at" date for the issue is back in July - Winnie asks for confirmation that this is actually an old, stale issue - the last 3 weeks of tests look good for Bristol, but the nagios link cuts off mid-July. Waiting for reply (16/8)
QMUL
123400 (15/8)
Another low availability ticket - following the nagios link here I see a lot of "-1.00" entries - which I think are caused by tests returning unknown statuses - Daniela is rightfully suspicious of it. There may be clues in this talk, but probably worth doing as suggested and just On Holding the ticket. Assigned (15/8)
A few tickets that could do with an update:
117683 - Glue 2 for Castor
122364 - cvmfs support for solidexperiment.org (looks like it's nearly done).
And finally, so long JET!
122198 (17/6)
EFDA-JET's decommissioning date is the 25th.

Tools - MyEGI Nagios
|
19th July
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 document describing Availability reliability calculation in ARGO tool.

VOs - GridPP VOMS VO IDs Approved VO table
|
Tuesday 19th May
- There is a current priority for enabling/supporting our joining communities.
Tuesday 5th May
- We have a number of VOs to be removed. Dedicated follow-up meeting proposed.
Tuesday 28th April
- For SNOPLUS.SNOLAB.CA, the port numbers for voms02.gridpp.ac.uk and voms03.gridpp.ac.uk have both been updated from 15003 to 15503.
Tuesday 31st March
- LIGO are in need of additional support for debugging some tests.
- LSST now enabled on 3 sites. No 'own' CVMFS yet.

Site Updates
|
Tuesday 23rd February
ALICE:
All okay.
RHUL 89%:89%
Lancaster 0%:0%
RALPP: 80%::80%
RALPP: 77%:77%
- 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.
