Tier-1 - Status Page
|
Tuesday 7th June
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- There have been problems with the RAL Tier1 tape library. There was an intervention on Wednesday (1st June) during which some components were replaced. However, one of these had a fault that led to a short circuit. The library was taken down from Thursday (2nd) to Friday (3rd) for checks to be made and there was no tape access during this time. At the end of Friday afternoon the service was restored. We also have an ongoing problem with the control software crashing. This does not have a big impact on the service at the moment. However, we have announced (via the GOC DB) an intervention today while we investigate it.
- "GEN Scratch" storage in Castor will be decommissioned. This has been announced via an EGI broadcast. Write Access to this area was disabled last week - ahead of full withdrawal in a few weeks time.
- One of our three WMS systems (lcgwms06) is being decommissioned. It was stopped from receiving new work last wek (on the 1st June).
- Reminder: HEP SYSMAN at RAL 21-23 June. The first day being a Security training day. Please register ASAP! See: http://hepwww.rl.ac.uk/sysman/june2016/main.html

Statement on recent history of LSST VOMS records. To be discussed at Ops Meeting.
- Feb 16: 3 x VOMS servers, port 1503, names: voms.fnal.gov (DigiCert-Grid, admin), voms1.fnal.gov (DigiCert-Grid, not admin), voms2.fnal.gov (opensciencegrid , admin).
- Apr 18: 1 x VOMS server. port 15003, names: voms.fnal.gov (opensciencegrid, admin). Caused by a hitch with security that caused the omission of some data. GGUS: https://ggus.eu/?mode=ticket_info&ticket_id=120925. Fixed.
- Apr 21: 3 x VOMS servers, port 15003, names: voms.fnal.gov (opensciencegrid, admin), voms1.fnal.gov (opensciencegrid, not admin), voms2.fnal.gov opensciencegrid admin
So, similar to how it was in feb, but DNs (and CA_DNs) of 2 certs changed. But other things to note:
Please discuss.

35 Open UK Tickets this month - I'll format these properly before the meeting, I promise.
NGI

Uncertified NGS sites to clear up - Jeremy has been on it. In Progress (17/5)
SUSSEX
118289 (10/12/15)
Pilot ticket - Jeremy M thought he had got it, but Daniela's tests say otherwise (although the errors look like the CE playing up). In progress (26/5)
121797 (26/5)
Sno+ dirac jobs failing at Sussex - looks like the same problem as above. No word from the site - I'll poke Jeremy M offline. Assigned (26/5)
120735 (11/4)
Low availability ROD ticket. Hopefully Sussex will have a clear month. On Hold (6/6)
OXFORD
121641 (18/5)
Wrong capacities reported in REBUS - this ball has landed in Oxford's court, with Pete G looking at the SE publishing. Assigned (I set it In Progress) (3/6)
121924 (2/6)
An interesting ticket from Duncan, concerning a drop in perfsonar throughput performance at Oxford. Still just Assigned (2/6)
BRISTOL
120455 (29/3)
Validation of a new HTCondor CE at Bristol by CMS. At last check Bristol were testing the CERN accounting daemon, but that was a few weeks ago. Any news? In progress (9/5)
121989 (6/6)
Super-fresh ROD ticket (.glexec.CREAMCE-JobSubmit tests). Assigned (6/6) Update - solved 10 minutes after a wrote this.
BIRMINGHAM
121125 (28/4)
Missing ATLAS SE dumps. At last check Matt W was having troubles with xrdcp-ing the dumps into his DPM, Alessandra suggested that others succeeded using rfcp (with the caveat that rfcp might not be around much longer). In progress (1/6)
GLASGOW
120135 (11/3)
HTTP support ticket. Any news? An update would be nice, no matter how vacuous. On holding the ticket would be even better. In progress (7/4) Update - Solved, tests are green.
121929 (2/6)
Glasgow's SE "not working" for Biomed- which it isn't meant to - but biomed support was still being published. Gareth is sorting that out, and will close the ticket once the Biomed references are purged. All good. In progress (3/3)
120351 (22/3)
Enabling LSST at Glasgow. I'll repeat Alessandra's question in the ticket - any news? On hold (5/5)
EDINBURGH
121465 (11/5)
ROD Availability ticket, just waiting for time to pass. On hold (31/5)
121990 (6/6)
BDII issues caused a few ROD test failures - Marcus fixed things around lunchtime, hopefully they heal up soon (to answer Marcus's question, I believe BDII changes typically take 2-3 hours to fully propagate). In progress (6/6) Update - can likely be closed, tests are green again.
120004 (7/3)
ROD test failures for the ARCHER test CE. The last update has Andy asking if the ticket could be put on "long term hold"? That's if someone can't manually edit the gocdb to set this service "Monitored=N, Production=Y". On hold (24/5)
SHEFFIELD
121991 (6/6)
A fresh ROD ticket, srm tests were failing. Elena freed up some space and things should be good now. Waiting for reply (6/6) Update - tests are passing, another for the solved pile?
LIVERPOOL
121759 (25/5)
Another Availability ROD ticket. John identified the cause as likely due to the DPM publishing problems after a cert upgrade (that's got me too before). Just needs time to heal these wounds now. On hold (27/5) Update- actually the ticket isn't on hold, but it should be...hint...
RHUL
https://ggus.eu/?mode=ticket_info&ticket_id=121575 (16/5)
Yet another availability ticket (May was not kind to the UK). Likely needs On Holding whilst the metrics "fix" themselves - if the underlying problems have passed. In progress (16/5)
QMUL
https://ggus.eu/?mode=ticket_info&ticket_id=120352 (22/3)
LSSt support at QM. Dan reports today that LSST should be enabled on three CEs. Nice one. Waiting for testing. (6/6)
https://ggus.eu/?mode=ticket_info&ticket_id=120204 (15/3)
LHCB problems, due to an issue submitting jobs to dual stack CEs from CERN. The referenced issue (120586) has had a priority bump and a few extra parties cc'd in, so hopefully there will be some movement on it. On Hold (25/4)
BRUNEL
https://ggus.eu/?mode=ticket_info&ticket_id=121573 (16/5)
ROD BDII issue ticket - possibly due to multiple site BDIIs (although I was under the same impression as Daniela). Kashif has opened a related ticket (https://ggus.eu/index.php?mode=ticket_info&ticket_id=121760 which Raul commented on today to asj for confirmation the issues are related). On hold (27/5)
https://ggus.eu/?mode=ticket_info&ticket_id=121813 (27/5)
Brunel failing CMS validation - likely due to cvmfs playing up on two nodes. The ticket has turned a conversation on CMS site settings, and seems to be chugging along fine. In progress (6/6)
EFDA-JET
https://ggus.eu/?mode=ticket_info&ticket_id=121899 (1/6)
Low availability JET ticket. Assigned (1/6)
https://ggus.eu/?mode=ticket_info&ticket_id=121837 (30/5)
JET SE not working for biomed. I thought that JET stopped supporting Biomed a while ago, I'll need to check my notes. Assigned (30/5)
100IT
https://ggus.eu/?mode=ticket_info&ticket_id=121189 (2/5)

Tools - MyEGI Nagios
|
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.
Tuesday 6 Oct 2015
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.
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.

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.
