Monday 26th September

Monday 19th September


Tuesday 13th September

  • There was an ops coordination meeting on 1st September. Agenda|Minutes.
  • News from the WLCG accounting Task Force: The new accounting portal with changes performed for the WLCG view is ready for validation.
  • EL7 plans from the experiments were presented at 1st September WLCG ops coordination meeting and summarised in the minutes twiki. Site plans will soon be collected by WLCG Operations.


Tier-1 - Status Page

Tuesday25th October A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

  • In response to CVE-2016-5195, the Tier1 has decided to stop access to any services considered particularly vulnerable eg. the CEs, the UIs, the perfsonar boxes, some web servers. The the GOCDB entry for full details.
  • Following the replacement of the "UKLight" router that handles the data traffic in/out of the Tier on 5th October we have seen significantly more data flowing across the "non-OPN" bypass route.
  • Some changes were made to increase the number of CMS batch jobs that we run in order to bring the number more into line with the pledge.
  • We have had load issues for both the Atlas Scratch Disk and on the Castor 'GEN' instance. This latter caused some access problems for all users of 'GEN' (e.g. Alice).
  • Owing to staff availability the upgrade of Castor to version 2.1.15 is being scheduled to tale place in January.
Storage & Data Management - Agendas/Minutes

Wednesday 26 Oct

  • Feedback from WLCHEPiXG - don't miss it!

Wednesday 19 Oct

  • Long list of loose ends - accounting and information systems, IPv6 surprising successes

Wednesday 12 Oct

  • Initial impressions from WLCG workshop and CHEP-so-far
  • Coming events where GridPP storage-and-data-management could be, will be, or should be (re)presented.

Wednesday 05 Oct

  • GridPP (re)presentations at WLCG workshop (coming weekend) and CHEP (next week), and cloud workshop at Crick (Nov.)
  • Grid specific stuff - and interoperations and interconnecting infrastructures - and future requirements and technologies

Wednesday 28 Sept

Tier-2 Evolution - GridPP JIRA

Monday 24th October

  • Started HTCvcm (HTCondor Vacuum VM), using ATLAS VMs as the starting point, to provide a generic HTCondor client VM that will connect to HTCondor pools run by the local site, experiments, or larger sites.
  • Merging LHCb multipayload VM code into DIRAC Pilots repo.

Monday 17th October

  • Validation of APEL accounting of VM resources and VM-only sites has been completed.
  • From 4th October: A Lightweight sites questionnaire for WLCG sites has been circulated. The aim is to get to a "matrix" of approaches that sites can choose from, depending on criteria that is covered in the questionnaire.

Tue 10 Oct

  • Vac-in-a-Box 00.34 supports Vac 01.00 itself rather than pre-release (note that upgrading to 01.00 requires a reboot due to network layout changes)
  • "Vacuum Platform" specification published as HSF-TN-2016-04

Wed 05 Oct


Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06

Monday 26th September

  • A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.

Tuesday 14th June

  • GridPP accounting switched to use the 'new' EGI accounting portal.
  • APEL delays from UK sites look about 'normal' (i.e. delays are typical).

Tuesday 9th February

  • 4th Feb: The data from the APEL summariser that was fixed yesterday has now propagated through the data pipeline and the Accounting Portal views and the Sync and Pub tests are all working again.
  • Sheffield is slightly behind other sites (but looks normal) and so is QMUL.


Documentation - KeyDocs

Tue 20th Sept GridPP Approved VOs now has link to RPM versions of the VOMS records. They are available for now via the VOMS RPMS Yum Repository. The latest version, which is consistent with the Yaim records in the Approved VOs doc, is 1.0-1. Plan is that when VO records change, Approved VOs doc version will be incremented, and RPMs of changed VOs (only those) will be released carrying the same version stamp as the document. Thus a site that upgrades to "latest" will get the records compatible with the newest version of the GridPP Approved VOs document.

Note: A typical RPM contains as so:

[sjones@hep169]$ rpm -qlp gridpp-voms-dteam-1.0-1.noarch.rpm 
/etc/grid-security/vomsdir/dteam
/etc/grid-security/vomsdir/dteam/voms.hellasgrid.gr.lsc
/etc/grid-security/vomsdir/dteam/voms2.hellasgrid.gr.lsc
/etc/vomses/dteam-voms.hellasgrid.gr
/etc/vomses/dteam-voms2.hellasgrid.gr
/root/vo_xml/dteam.xml

The vomsdir (lsc) files (which list the DNs and CA DNs of acceptable certificates) and the vomses files (which give the coordinates of VOMS servers of various VOs) are provided, as if they were created by YAIM in the normal locations. No other features of YAIM are facilitaed by these RPMs. Thus they are useful for migrating from YAIM, but do not provide all the functions of YAIM such as setting SW dirs or other ENV vars etc.

Tue 6th Sept Benchmarking procedure. Contains instructions for ARC/Condor, CREAM/Torque, VAC. Needs to be updated for use with other systems.

https://www.gridpp.ac.uk/wiki/Benchmarking_procedure

Mon 1st Aug LZ VO now up to date in portal, and will be updated in Approved VOs automatically from now on. Sites supporting LZ are advised to read LZ VOMS settings section of https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs (which is between LSST and MAGIC!)

Tue 26th July

Elena has provided VOMS info for DUNE. I'm maintaining it by hand, at present, similarly for LZ.

Both should be present and correct in the Operations Portal, but are not.

Monday 19th September

  • Fairly quiet week, with just the usual suspects.
  • ROD responses received.

Monday 22nd August

  • Unusually quiet week. Nothing significant.
  • Portal very slow at times though.
  • New rota meet-o-matic request circulated - ROD team members please respond this week!

Security - Incident Procedure Policies Rota

Monday 24th of October

  • Dirty COW vulnerability - CVE-2016-5195
    • Sites are asked to act to mitigate this as soon as possible - see the advisory. Hopefully by the time the meeting comes we'll have more information on an SL fix (SL7 is available) - when this comes sites will have 7 days to update. Sites not able or wanting to apply mitigation before official patches are available have the option to go into Downtime, without penalty of loss of availability (until 3 days after official patches are available, agreed by EGI Operations).
  • EGI-SVG-2016-11476 (canl-c)
    • One or two sites still popping up on the monitoring each week.

Monday 17th October

  • Due to problems with pattern matching filters, Pakiti was not complaining about some instances until recently. This was in connection to vulnerability EGI-SVG-2016-11476.
  • There was an EGI Trust Anchor release 1.78-1. Please upgrade by 2016.10.18 at your earliest convenience. Please check the release notes for more details
  • FedCloud Sites have received a 'Heads Up'.
  • We are down to a few SL5 services.

Tuesday 4th October

  • Sites not upgrading for EGI-SVG-2016-11476 have now been ticketed by EGI CSIRT. Although WNs not thought to be vulnerable they are asked to be upgraded as indicator of compliance elsewhere. No UK sites have been ticketed _BUT_ it looks like the monitoring is only working through CREAM CEs so there may be ARC CE installations that would show "vulnerable" if/when the monitoring is fixed. Please check.

Services - PerfSonar dashboard | GridPP VOMS

- 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 25th October

  • Duncan has recreated the UK perfSONAR mesh. Link here!


Monday 19th September

  • UK eScience CA - certificate issuance problems. Jens reported that on 15th a partial but significant database corruption occurred on the signing system for the CA. Data was restored from (offline) backups but the rebuild was not correctly configured.
  • A large number of site admins and other GridPP supporters appeared to be suspended from the dteam VO last week. “During a planned upgrade operation of VOMS service, a system malfunction occurred. As a result, some users received false notification about membership expiration. We are in contact with the software development team in order to identify the cause.”


Tickets

Monday 24th October 15.00 BST
32 Open UK Tickets'
Just another lite update this week.

Looks like they can be closed:'
123504 (20/9) - Tier 1 T2K ticket, with T2K quiet on the grid and Jon P's departure I would close this ticket.

124411 (12/10) - QMUL ticket regarding IceCube GPU glideins. Looks like things are working and the ticket can be closed, interesting stuff though.

Need an Update:
122378 (4/10) - Glasgow Perfsonar ticket. I'm being a bit unfair singling this one out though.

123870 (14/9) - Manchester Perfsonar ticket.

121687 (10/10) - Tier 1 Perfsonar ticket - a reminder to update how do things look after a fortnight of statistics with the new router.

123962 (13/10) - Liverpool biomed ticket, after being taught the wonders of space tokens by John I noticed that Sorina's update contained a question that could do with a response.

124244 (5/10) - Tier 1 Ticket from LHCB for a cvmfs issue at RAL. Is this still a problem? No update for 19 days.

124431 (14/10) - Tier 1 ticket from atlas regarding a frontier squid. Checking the plots things still don't look right (at least to my eyes). Update - thanks to Alessandra for closing the ticket, the (unmaintained) monitoring was lying to us!

Tools - MyEGI Nagios

13th September 2016


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

  • 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.
