Week commencing Monday 2nd July 2018
Task Areas
General updates

Monday 2nd July


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.
WLCG Operations Coordination - AgendasWiki Page

Monday 25th June

Monday 16th April

  • There was a meeting on 12th. Agenda | Minutes.
    • Balazs Konya is new in the role of WLCG Middleware Officer.
    • Next meeting 7th June.
    • Delay for submission of GGUS tickets for recalculation should be respected. It is 10 days after monthly drafts of the availability reports are sent around by WLCG project office. If the GGUS tickets are not submitted respecting 10 days delay, they are not accepted.
    • A/R recalculations will be accepted if they are relevant to the site MoU commitment or concern time ranges of sufficient length.

Monday 5th March

  • The agenda and minutes from the WLCG ops coordination meeting last week are available.
  • Special topics were: CNAF recovery update; SAM recalculation policy draft discussion and Progress on WLCG Storage Space Accounting Prototype including tape metrics.

Tuesday 27th February


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.
Storage & Data Management - Agendas/Minutes

Wed 13 June

  • Future directions for T2s with DPM?
  • Assessing storage requirements for IRIS

Wed 06 June

  • Report from DPM workshop

Wed 30 May

  • Problems with deep vs shallow checksums in implementations - does the system present the checksum the data has or the checksum it thinks the data should have?
  • IPv6 use - how to ensure IPv6 only transfers

Wed 16 May

  • Operational issues some of which at least are due to timeouts hardwired in the system.
  • Report on CERN data lakes - still lots of questions, though. Maybe if we could try it out?

Wed 02 May

  • DPM DOME discussion... will Glasgow (or someone else) volunteer to test before DPM workshop?
  • Storage agenda for HEPiX
Tier-2 Evolution - GridPP JIRA

Tuesday 3rd July"

  • "Universal" DIRAC VMs deployed in production for GridPP DIRAC and LHCb

Tickets

Monday 2nd July 2018, 15.00 BST
33 Open UK Tickets this month.

IPv6 Tickets (14)
SUSSEX: 131617
RALPP: 131616
OXFORD: 131615
CAMBRIDGE: 131614
BRISTOL: 131613
BIRMINGHAM: 131612
GLASGOW: 131611
ECDF: 131610
DURHAM: 131609
SHEFFIELD: 131608
MANCHESTER: 131607
LIVERPOOL: 131606
UCL: 131604
RHUL: 131603

Oxford, Bristol, Sheffield, UCL and maybe Glasgow's tickets are all a little stale. The RALPP, Manchester and RHUL tickets really need an update due to various reasons.

Regular Tickets.

BRISTOL
135618 (11/6)
CMS SAM test stageout failure. Last update from Friday things are waiting for the site-local-config to be changed, which is in hand. In progress (29/6)

134820 (29/4)
CMS DDM quota ticket - after a long while CMS provided some feedback as to what they would like their quotas adjusted to. After this is done then hopefuly this ticket can be closed. In progress (26/6)

BIRMINGHAM
129930 (4/8/17)
The "atlas http SAM test" ticket soon to be rendered moot by the deployment of EOS at the site. The ticket could do with a progress update, in part to see if you need atlas to do anything. On hold (23/4)

GLASGOW
134689 (23/4)
Perfsonar upgrade ticket. 4.1 is due out this quarter I believe, so the anointed time to upgrade will soon be upon you. On hold (24/4)

135621 (12/6)
Atlas deletion errors, much discussed. I agree that the site cannot do much, we'll need to keep pressure on the VO to fix things. In progress (21/6)

ECDF
135404 (30/5)
Low availability ROD ticket. The last week's looking green, so it's just a waiting game. On hold (28/6)

DURHAM
134687 (23/4)
Request to upgrade the perfsonar host to Centos 7. Set in progress but no news on this for a while. Could do with an update (even if it's just to take the Glasgow-stance). In progress (30/4)

SHEFFIELD
134947 (4/5)
Atlas transfers timing out. I believe Elena rolled out the gSOAP fix for the original issue, so it looks like a fresh cause of errors has popped up - checking the monitoring they're still there at at a rate of a few hundred a day. Reopened (11/6) Update - solved with a DB cleanup.

135851 (28/6)
T2K having trouble downloading files from Sheffield. It turns out that the files have disappeared from the site. The VO has offered to close the ticket, but it's a good idea to suggest that they delete these entries from their LFC first (if they haven't already). In progress (30/6)

LIVERPOOL
135852 (29/6)
A ticket assigned on Friday, atlas complaining that deletions aren't working. I suspect a fallen over httpd daemon. Assigned (29/6) Update - solved. The second pass of the automatic httpd restarter fixed things.

UCL
134686 (23/4)
I am once again regretting not spinning these off into their own list - another request to upgrade the site perfsonar hosts. No news since it since the ticket was acknowledged. On hold (23/4)

QMUL
134573 (17/4)
CMS request to install Singularity, on hold until the site's C7 upgrade. On hold (17/4)

132929 (18/1)
CMS spotting APEL problems. The ticket's been quiet for a bit, is there a conversation with the APEL devs happening along a different channel? In progress (10/5)

BRUNEL
135871 (1/7)
LHCB have noticed a black hole node gobbling up pilots at Brunel. Assigned (1/7) Solved by offlining the bad node.

133956 (9/3)
CMS xroot config ticket. CMS would like to know if there's any progress? In progress (15/6)

100IT
135786 (22/6)
A simple availability ticket, made a bit horrid by all the auto-replies from the 100IT helpdesk system. On hold (28/6)

TIER 1
134685 (23/4)
The last of the requests to upgrade the perfsonar hosts. Last update was positive. In progress (11/6)

135822 (26/6)
CMS jobs seeing file read problems. Quite a complex issue, but it looks to be a problem with singularity and bind paths - a corresponding singularity issue has been opened (here). In progress (29/6)

124876 (7/11/16)
The oldest ticket, this ROD ticket for ECHO was waiting on the tests to be fixed. As seen in the now solved (125026) it looks like things should work (or at least be able to be made to work). But it requires some setup at the site tweaking the SE_PATH, this is underway. Reopened (28/6)
