CMS ticketing RALPP essentially because their multicore jobs aren't getting slots.  Chris notes this problem may be compounded by these CMS jobs being particularly RAM-hungry in their resource requirements.

Monday 6th March 2017, 15.00 GMT
21 Open UK Tickets this month

TIER 1 and IMPERIAL
126808 (24/2)
WMS "Usage Survey" ticket. Both WMS sites have replied and it has been noted that the two big WMS users in the UK (mice and t2k.org) can be encouraged to use dirac. In progress (28/1)

SUSSEX
122772 (11/7/16)
Atlas webdav/xroot ticket. It's a bit of a baptism of fire for the new admin, and any luck with this? The storage group are always happy to help. On Hold (26/1)

OXFORD
126928 (3/3)
Atlas transfer failures ticket - Kashif spotted that the gridftp service wasn't listening and restarted it - I suspect this ticket can be closed but is it me or has the gridftp service been a bit flakey recently (particularly for Oxford?). In progress (3/3)

A ticket to track LZ deployment at Bristol. Ticking along. In progress (1/2)

124819 (3/11/16)

126838 (27/2)
Atlas "space reporting issue" ticket. Brian is aiding the investigation, spotting a large amount of possible dark data creation via botched deletions during the switch to webdav. The discussion moves onto problems inherent using webdav for deletions on storm. This has been talked about in the atlas uk meeting (although I'm afraid I phased out during the conversation). In progress (6/3)

TIER 1
126184 (26/1)
Atlas site monitoring survey ticket. Possibly closing soon? Has feedback been provided? In progress (7/2)

126889 (1/3)
Atlas deletion error ticket for the Tier 1. Again it looks like the problem has gone away, although Tomas kindly provided the error message that was being seen for investigation. In Progress (6/3)

126905 (2/3)
Finishing up with deployment of the cvmfs support for solidexperiment.org - focusing in part on accepted upload proxies. This looks to have been done, and Dan the new solidexperiment chap has success in uploading software. Daniela has updated the ticket with a few new questions. In progress (6/3)

117683 (18/11/15)
Castor Glue2 publishing ticket. Rob reports that much of the code has been written. On hold (2/3)

124876 (7/11/16)
The echo instance not working for nagios tests due to the wrong path being used. No movement on the child ticket 125026 - it looks like some chasing is needed to be done by someone. On hold (1/1)

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.

Atlas S&C week 2-6 Feb 2015

Production

• Prodsys-2 in production since Dec 1st

• Deployment has not been transparent , many issued has been solved, the grid is filled again

• MC15 is expected to start soon, waiting for physics validations, evgen testing is underway and close to finalised.. Simulation expected to be broadly similar to MC14, no blockers expected.

Rucio

• Rucio in production since Dec 1st and is ready for LHC RUN-2. Some fields need improvements, including transfer and deletion agents, documentation and monitoring.

Rucio dumps available.

Dark data cleaning

files declaration . Only Only DDM ops can issue lost files declaration for now, cloud support needs to fill a ticket.

• Webdav panda functional tests with Hammercloud are ongoing
