On-duty - Dashboard ROD rota

Tuesday 29th April

  • Ongoing problems with the dashboard. Issue escalated to EGI.
  • There was an update of Dashboard last Thursday which solved a few issues. It no longer shows warning alarms which is good. There were some other improvements as well.
  • EMI-2 deadline is approaching. The following need attention and are about to be escalated:
  • RHUL (cream2.ppgrid1.rhul.ac.uk) ) Last update in ticket: 16/4
  • Sussex (grid-cream-01.hpc.susx.ac.uk, grid-bdii.hpc.susx.ac.uk,) (Plus Sha-2 compliance for grid-cream-01.hpc.susx.ac.uk) ) Last update in ticket: 16/4
  • Bristol (lcgce03.phy.bris.ac.uk, lcgce04.phy.bris.ac.uk, lcgbdii.phy.bris.ac.uk) ) Last update in ticket: 23/4
  • ECDF (info2.glite.ecdf.ed.ac.uk, ce7.glite.ecdf.ed.ac.uk) Last update in ticket: 28/4
  • Durham (ce1.dur.scotgrid.ac.uk, se01.dur.scotgrid.ac.uk) ) Last update in ticket: 23/4

Tuesday 22nd April

  • There were ongoing problems with the dashboard last week. Several bugs, possibly including one related to the email function, have been fixed.
Rollout Status WLCG Baseline

Tuesday 18th March

Tuesday 11th February

  • 31st May has been set as the deadline for EMI-2 decommissioning. There may be an issue for dCache (related to 3rd party/enstore component).


Security - Incident Procedure Policies Rota

Tuesday 29th April

  • The changes to the regional dashboard make the on-duty task harder. Need to rely on Pakiti again.

Tuesday 15th April

  • Update on the OpenSSL status.
  • The discussion list members have been updated. Anyone missing?

Services - PerfSonar dashboard | GridPP VOMS

Tuesday 29th April

  • It was mentioned several weeks ago that the perfsonar meshes were being sorted by host name and that sorting by site name would be available soon. This is now the case. You can see the familiar GridPP site sorting here and the large WLCG mesh here. Note the square of GridPP sites towards the bottom right. Red squares represent throughput of less than 500 Mb/s.

Tuesday 15th April

  • New LiveCD and LiveUSB images are now available containing the latest openssl packages (see email of 11th April).

Tuesday 8th April

  • Some discrepancies found in VOMS ports and listings between VOMSsnooper and the dashboard for ops. (15009 vs 15002.
  • Also noted WLCG VOMS changes. New VOMS servers are being introduced as notified in this broadcast.

Monday 28th April 2014, 16.30 BST
I'm afraid the ticket roundup is incredibly light and not in the usual (or any) format.

EMI upgrade tickets: ECDF, Bristol, RHUL, Durham, EFDA-JET, Glasgow, Sussex, UCL and RALPP all have open EMI upgrade tickets. Can everyone with an open ticket please update it this week (preferably buy the first) if they haven't done so in the last 7 days (or if you have but have made progress since then). It's a lot easier for the Person on Duty to extend tickets when there's site updates to validate their actions.

(RALPP have submitted https://ggus.eu/index.php?mode=ticket_info&ticket_id=104839 in response to an argus problem they were seeing post upgrade).

UCL have another Nagios error ticket: https://ggus.eu/index.php?mode=ticket_info&ticket_id=104824

Interesting One: https://ggus.eu/index.php?mode=ticket_info&ticket_id=104937 Manchester received a ticket from Steve Traylen regarding a lot of connections to the CVMFS stratum 1. Andrew confirms these are VAC machines (unless I've misread something). It looks like the local squid cache was being ignored, Andrew is on the case.

Afraid that's it from me. Next week's will be better (because it's the first Monday of the month... that came around quickly!).

Tools - MyEGI Nagios

Monday 17th March

Tuesday 26th November

  • Regional Nagios updated to release 22. It is a glite to UMD update and it required a fresh installation.
  • There have been some internal changes in SAM-Nagios. Test probes are now the responsibility of product team. Some test names have been changed as a result of this reorganization. For example the org.sam.CREAMCE-DirectJobSubmit test has become emi.cream.CREAMCE-DirectJobSubmit. This does not affect the operational activities.
  • Please could all site admins look at services associated to their site and please mail Kashif if anything odd is noticed. Site admins can reschedule tests for their sites and it would be helpful if most functionalities are tested.
  • Also, look at myegi which can be useful with links to the Dashboard, GSTAT, Accounting Portal and GGUS.
VOs - GridPP VOMS VO IDs Approved VO table

Tuesday 15th April

  • Is there interest in an FTS3 web front end? (more details)

Monday 17 February 2014

  • Proxy renewal
    • All RAL WMSs now renew proxies with 1024 bits. This looks like the end of this (at last).

Tuesday 11 February 2014

  • Proxy renewal
    • lcgwms06 at RAL has been upgraded and works
    • Both Imperial's WMSs work
    • Glasgow's will still need to be upgraded (unless they have been since Friday).
Site Updates

Tuesday 8th April

  • Steve noted that Liverpool are having a problem with the CVMFS clients on their workers nodes. "...in short, VO/CVMFS admin for na62 and mice are publishing stale .cvmfswhitelist and repos cannot be mounted on new systems. I expect this to spread to other systems and VOs as local cache dates expire."
