Monday 25th June


Monday 11th June

  • There is a pre-GDB Tuesday on benchmarking.
  • There is a June GDB on Wednesday.
  • HEPSYSMAN is next week 18th-19th June - so no ops meeting next Tuesday.
  • Winnie – 8th June problem with argo-mon.egi.eu
  • Progress towards running LSST DESC data challenge on GridPP. Lack of multicore option in DIRAC for per VO basis.
  • DPM 1.10.2 update issue
  • dCache and IPv6: GridFTP doors and pools require that if a client can connect to an IPv6 address on an interface, that interface should also have an IPv4 address to which that client can connect.
  • Brian: requested input last week to Hardware for Grid SE page.
  • Of note: VO vo.geoss.eu status from Pending to Production
  • APEL: delay in processing VM accounting records and new cloud data appearing in the Portal during the week of the 11th to 15th June. This is so that the APEL Repository can be updated to correctly assign the usage VMs incur to individual months when they run over month boundaries (i.e. long running VMs). This requires reloading a large volume of existing cloud accounting data once the update has been applied.
  • May A/R (waiting for replies to 6th June request):
    • ALICE All OK
    • Atlas RHUL 81% Lanc 86%
    • LHCB RHUL 76% Bristol 74% (Availability only)
    • CMS Bristol 77%
  • WLCG weekly ops meeting minutes from Monday 11th.
  • Today there are issues affecting the databases that GOCDB relies on, leading to very slow responses through the portal and API.

    • A/R recalculations will be accepted if they are relevant to the site MoU commitment or concern time ranges of sufficient length.


Tier-1 - Status Page

Tue 25 June Report for the Experiments Liaison Report (02/07/2018) is here.

  • ADVANCE WARNING : There is currently a scheduled three day period (July 24th - July 26th), where RAL Tier-1 will be undertaking server room circuit breaker testing. Although it is believed that these tests should not effect our services, such is the nature of these tests all Tier-1 production services should be considered "At Risk" during this time. All VOs are asked to give consideration with respect to possible unexpected outage to any high priority/critical jobs they may wish to run during this period.

RALPP: 131616
Back in January Chris was thumping IPv6 on his perfsonar boxes into shape. I don't think you're still flogging that problem. How goes things? In progress (31/1)

OXFORD: 131615
Some good news delivered with some new switches back in March. Any update since then, now that Summer is well and truely upon us? On Hold (6/3)

CAMBRIDGE: 131614

BRISTOL: 131613
At the last update Bristol admins were debating how to get an perfsonar box onto an IPv6 network back in April. Any luck with that? On hold (11/4)

BIRMINGHAM: 131612
Some good progress IPv6-ing his perfsonar box back in May, did you get the v6 DNS working? On hold (28/5)

GLASGOW: 131611
I don't want to really ask this, as I have an inkling as to the answer and it kind of feels like adding insult to injury, but how goes the new data centre? On hold (26/2)

ECDF: 131610
The busiest v6 ticket by far, if I'm reading things right things are waiting until a big networking procurement in September. Is this still the case? On Hold (21/5)

Any joy with this? Did the IT department get round to deploying v6 reverse DNS? In progress (4/5)

SHEFFIELD: 131608
Things took at positive turn at the end of April, with news that the University would work towards deploying IPv6 - but it was only at the approving the work to be done level at that time. Any news since? On Hold (30/4)

MANCHESTER: 131607
Good progress getting the perfsonar boxes dual-stacked, any plan of attack for doing the same for your DPM? On Hold (25/4)

LIVERPOOL: 131606
Waiting on new routers to deal with the rubbish IPv6 performance Liverpool are seeing. Any news since last months update? In progress (4/6)

UCL: 131604
Not much news here, Ben's been occasionally repoking UCL Networks. As noted UCL only need to dual stack their perfsonar boxes to satisfy this ticket. On hold (5/6)

RHUL: 131603
At last update in February the perfsonars were dual-stacked but once again v6 DNS lookup wasn't supported yet - did they manage to get it working? On Hold (23/5)
