- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).

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.

Monday 4th April 2016, 14.00 BST
26 Open UK Tickets this month.

119995 (7/3)
Uncertified site ticket for the UK - Jeremy is on the case, and there appears to be no need to rush. In progress (4/4)

120588 (4/4)
A fresh ticket, saying we have achieved insufficient "Quality of Support performance" - we had an average of a 1.4 day response time for very urgent tickets during March.

I've looked into this using the ggus report viewer and I believe we're being accused of a crime we only technically committed (if I'm looking at things right). We only had 2 "very urgent" tickets in this period, and one of them the site forgot to put In Progress, so had an erroneous response time of two and a half days. When averaged with the single other very urgent ticket this gave us an average response time > 1. Poor statistics is a right blimmer. I've updated the ticket - which was solved whilst I wrote the report.

The take home from this - please remember to set your tickets In Progress! It does actually matter (kinda).

118337 (14/12/15)
Sussex Storage down for Sno+ - I assume this is still the case? Jeremy M replied a while ago but no news since. On Hold (15/2)

117894 (23/11/15)
One of the last Atlas Consistency Checking tickets - in a similar state to the former. On Hold (25/1)

118289 (10/12/15)
gridpp pilots at Sussex- again no news. On Hold (25/1)

I was supposed to poke the Sussex tickets before Easter but local things came up - I will prod them after tomorrow's meeting if we don't get a chance to discuss them during.

118628 (5/1)
LZ support at RALPP. Chris tried to roll out the LZ-friendly test version of ARC to a production server but hit a roadblock and had to rollback. Chris is waiting on the fix to go out into the proper repositories, and is interested to see how things fair on a test centos7/umd4 ArcCE he has brewing (no pun intended). On hold (22/3)

120282 (18/3) Atlas HTTP taskforce ticket. Chris has asked that the tests be re-aimed at another, less-loaded server. Waiting for reply (1/4)

120019 (7/3)
A CMS ticket asking the Oxford T3 to change its xrootd federation subscription. Ewan was the chap who first-responded to this ticket, quiet since - it needs some attention. In progress (7/3)

117892 (23/11/15)
The other holdout of the Atlas Storage Consistency Checking tickets, and again in a similar state. In progress (24/3)

120345 (22/3)
At atlas ticket asking Oxford to update their xroot monitoring settings. Kashif battled this issue with Ilija's help, and with luck it can be closed. In progress (31/3)

119957 (4/3)
A ROD availiability ticket after their SE DB crisis, just waiting to for the alarms to go green. On hold (31/3)

117706 (19/11/15)
Pheno (and other?) pilots at Glasgow. Gareth reports that they should have their new identity management system up and running soon (it it arrived on time). On Hold (23/3)

118052 (30/11/15)
ATLAS HTTP Taskforce ticket. Reopened just before Easter after tests started failing with TLS issues. Reopened (24/3)

120351 (22/3)
The first on a few enable LSST tickets - On Hold until the new identity management system is up and running. On hold (23/3)

120135 (11/3)
I'm not entirely sure why you chaps got a second http TF ticket, but you have (for a slightly different issue). In progress (1/4)

120004 (7/3)
ROD ticket for the test ARC CE fronting ARCHER, where tests fail as expected. I remember years ago being among many who couldn't think of a good reason to keep the "Production=yes, Monitoring=no" option, so they got rid of it - but it would perfectly apply here. How long can the ROD keep this ticket on hold before the dashboard self-destructs? On hold (29/3)

118764 (12/1)
Another HTTP TF ticket. Elena kicked the services a while ago, but no news since (and the tests are still not passing by the looks of things). In progress (24/2)

114460 (18/6/15)
gridpp pilots at Sheffield. Did you get round to having a look at this? In progress (29/2)

120430 (24/3)
Ticket tracking setting up Manchester for Icecube glideins (the coolest of VOs...). It opens with a request to the Manchester site admins to enable their user (looks like just the one pilot DN), but no reply (as the Mancunians might have missed that the ticket has turned on them). Assigned (24/3)

LANCASTER 120412 (24/3)
Atlas deletion errors at Lancaster - caused by a few files badly drained back in 2014. I'm trying to figure out a clever, database-y way of listing all the files on these long gone servers (the best I've got so far is `select * from Cns_file_replica where host like 'fal-pygrid-%';`, but of course the dpns mapping isn't that straightforward. Expect a cry for help soone! In progress (4/4)

119509 (12/2)
Sno+ job directories being cleaned up prematurely. It looks like this problem could have been transient - Matt M submitted some test jobs and didn't see the problem, and is re-testing with some proper work. Hopefully those tests completed okay. In progress (22/3)

120352 (22/3)
Request to enable LSST at QM. Dan has asked for a reminder after/during GRIDPP36. On hold (24/3)

120204 (15/3)
LHCB having issues with some of the QM CEs. The reasons for this are unclear - pilots stopped around the start of March and the problem persisted at last check. In progress (17/3)

117683 (18/11/15)
CASTOR not publishing GLUE2. It's being worked on in people's spare time - any recent news? If not, maybe progress is slow enough to warrant on-holding the ticket. In progress (17/2)

119841 (1/3)
HTTP TF ticket, this time for LHCB. Proxy functionality isn't working (although regular cert/key pair access is okay) - this functionality was never turned on and is being looked into. In progress (22/3)

120350 (22/3)
Request to enable LSST at the Tier 1. Daniela notes that the Tier 1 will likely hit the same problem as RALPP for LZ (118628), Andrew L concurs. Pool accounts have been requested, things chug along nicely. In progress (22/3)

Tools - MyEGI Nagios

Tuesday 5th April 2106

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.

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

  • For January:

ALICE: All okay.

RHUL 89%:89% Lancaster 0%:0%

RALPP: 80%::80%

RALPP: 77%:77%

  • Site responses:
    • 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.
