Documentation - KeyDocs

Tuesday 12th Dec 2017

Resources requirements for CMS have been increased.

https://www.gridpp.ac.uk/w/index.php?title=GridPP_approved_VOs#VO_Resource_Requirements

Jobs require an address space larger than the memory size specified above. Sites should allow processes to use at least 6GB of virtual address space more per core than memory to accommodate the large amount of shared libraries used by jobs. (For a typical 8-core pilot that would translate into a VZSIZE limit of at least 64GB.)

Nov 2017

VOMS servers located at CNAF have been knocked out due to some flooding. It is not known when they might be recorvered. Hence, at present, there are no VOMS servers at all for both planck or ipv6.hepix.org. And a single new VOMS server has been provided for enmr. See the VOMS records in the Approved VOs document for details.

Tuesday 5th Sept 2017

New Approved VO. SKA European regional data centre, skatelescope.eu

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

This VO is ramping up and has requested support. Andrew McNab is the contact person for GridPP.

General note

See the worst KeyDocs list for documents needing review now and the names of the responsible people.

Tickets

Monday 18th December 2017, 13.00 GMT
48 Open UK Tickets this week.

Tickets that can be hopefully closed:

SUSSEX
132189 (29/11)
This Sno+ ticket seems to be solved (at least at the site end) and the VO has said it can be closed. In progress (13/12)

132027 (23/11)
All the tests listed in this ROD ticket have been green for a while now, so this ticket looks like it can be closed too. Waiting for reply (14/12)

RALPP
132438 (11/12)
Chris needed to order new certificates to solve this atlas ticket, and planned to roll them out today. Hopefully there was a set of wins and this ticket can be closed. On hold (11/12)

130264 (28/8)
Whilst no one likes patching this close to Xmas, hopefully Chris can wrap up this biomed publishing ticket this week too. Good luck Chris! On Hold (6/12)

QMUL
132504 (15/12)
Dan caught the rogue node causing these LHCB troubles, so maybe this issue can be closed? In progress (15/12)

130262 (28/8)
The Storm Devs have given some advice on how to patch Storm to get Glue 2 publishing to work to satisfy Biomed. Of course you might want to leave this until next year as it does call for re-yaiming. In progress (14/12)

MANCHESTER
132422 (10/12)
Atlas deletion errors after one of the Manchester disk servers keeled over. Any word on the recovery? There haven't been many recent atlas deletion failures so this ticket looks like it could be closed. In progress (11/12)

TIER 1
132356 (7/12) Raja has confirmed that this LHCB file access ticket can be closed. Waiting for reply (18/12)

132336 (6/12)
Similarly this ROD ticket looks like it can be checked and then closed. In progress (18/12)

Ticket that need shoring up for the Holidays:

IPV6 TICKETS
If you have one of these ticket still open (which is most sites) and it's not On Hold yet (5 sites) then please can you consider putting it On Hold unless you plan to spend Christmas dual-stacking!

SUSSEX
122772 (11/7/16)
The atlas xroot/http ticket needs an update even if there's no news, and perhaps On Holding until it can be tackled again. In progress (18/10)

BRUNEL
132517 (15/12)
A CMS request to change the stageout plugin to gfal2 at Brunel. Not spotted yet by the site (but it did come in Friday evening). Assigned (15/12)

RALPP
132334 (6/12)
CMS stageout errors at RALPP. Chris tweaked a few things but at last check there were still errors, and the ticket could do with an update. In progress (7/12)

EDINBURGH
132446 (11/12)
LZ and LSST dirac jobs having problems at ECDF. Rob has kicked a few things, but after a brief period of LSST jobs passing we're back to both VOs failing with the same error message (gridpp dirac jobs aren't having any problems). Is there time for one last bash at this before the Holidays? In progress (14/12)

MANCHESTER
132121 (28/11)
Pheno noticing that their VOMS roles were occasionally disappearing. Any news on how the investigation's going? In progress (1/12)

The old storage accounting ticket. Any news? In progress (1/11)

TIER 1
132314 (5/12)
Most of the alarmed tests in this ROD ticket have gone green, but one fresh one has cropped up spoiling things- org.nordugrid.ARC-CE-sw-csh-ops "Could not find $PATH in the csh environment". Hopefully it will be an easy fix. In progress (11/12)

130207 (24/8)
Henry has tacked on a query on the health of Castor after noticing some MICE transfer failures last night, but this ticket could also do with an update, even if it's a boring one. On Hold (16/12)

131815 (13/11)
This T2K ticket could well be closable - Brian and Henry have provided their advice and the next thing to do is see if this worked for the VO. In progress (1/12)
