Tuesday 26th September A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

• There was a problem with the LFC service. A new node was added to the alias but it was not configured to support dteam VO. This was corrected in response to a GGUS ticket.
• A better understanding of CEPH problems with Echo has provided stability. However, careful management of the disks in servers recently added into Echo has been needed. This has slowed the rate at which the new hardware is being brought into full use.

Wednesday 30 Aug

• How will experiements use object stores in the future? Could the Sept. pre-GDB clarify this?
• Fair bit of stuff known about advantages and disadvantages of erasure coding data, compressing data, etc. prior to storing it.
• Bristol's curious missing SE - dropped out of the inforamtion system?

Tuesday 26th Sept 2017

• Safari on macOS autogenerated client certificates fix put into production last week.

Tuesday 19th Sept 2017

• Bug in Safari on macOS causes random Apple generated client cert to be presented to www.gridpp.ac.uk using a CA we don't know about. The connection is then rejected by Apache. Other browsers ok since we request but do not require that they supply a certificate. Workaround produced by (a) installing the Apple CA root and intermediary CA and (b) whitelisting UK e-Science DNs (+ CERN? Others?) in the HTTPS Wiki plugin. Tested but not yet in production.

• Staged Rollout pages (now separated into EMI1 & 2), and the page listing the deployed versions is extractable from the bdii, so they should all be reasonably up-to-date:

Monday 31st July

• Ian has now left GridPP. Please direct queries to the security team via ukngi-security at cern.ch.

- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).

Tuesday 4th July

• Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).

Tuesday 6th June

• An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.

Tuesday 25th April

• perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here

• Duncan has recreated the UK perfSONAR mesh. Link here!

23 Open UK Tickets this month.

SUSSEX
122772 (11/7/16)
Sussex have just the one ticket- the atlas xroot/httpd one. Last word was that Leo had contacted Dan at QM for help. In progress (5/9)

RALPP
130264 (28/8)
Biomed CE publishing ticket - Chris is waiting on the corresponding Brunel ticket (130263) to see how the fix offered works out. In progress (26/9)

OXFORD
130032 (11/8)
LHCB jobs failing on upload. The ticket occurred at a time of multiple SE troubles, and there's not been any news throughout September so first port of call will be to see if the problems persist. In progress (23/8)

130173 (22/8)
A ticket from Duncan about incomplete perfsonar results, with the likely solution being to reinstall to CentOS7. Kashif is on it. In progress (26/9)

129931 (4/8)
http SAM tests failing - for unknown reasons. Kashif hopes an update of the headnode will fix things. On hold (19/9)

CAMBRIDGE
130787 (28/9)
LHCB pilots failing at Cambridge. It looks like lhcb jobs are failing due to hitting a CPU time limit, although no changes have been made site side to break things. John proposed increasing the CPU limits. Waiting for reply (28/9)

BRISTOL
130646 (20/9)
Low CMS xroot HC rates. After some clarification on the problem Lukasz is looking at the xroot logs. Did you see anything? In progress (26/9)

BIRMINGHAM
129930 (4/8)
The Birmingham version of the Oxford http SAM test ticket. Although symptoms are slightly different it's equally hard to debug. Any news, or perhaps we can try to rally the troops for another bash at helping? In progress (16/8)

MANCHESTER
130868 (2/10)
A fresh ROD CE submission test failure ticket. Assigned (2/10)

LIVERPOOL
130518 (12/9)
One of those ROD availability tickets we all loathe. Steve kept us all in the loop, and hopefully things will go green soon. On hold (2/10)

LANCASTER
130753 (26/9)
Setting up na62 at Lancaster, things seem to be working for them after the usual back-and-forth and we just need some more jobs to flow. On Hold (26/9)

QMUL
130262 (28/8)
Another biomed publishing ticket, although this one is aimed at the SE. After some feedback from Biomed it looks like it's the glue2 bit that's broken. In progress (26/9)

IMPERIAL (well, Dirac)
130202 (24/8)
Not really a IC ticket, but one to all na62 sites - about na62 jobs waiting too long. Dan included a useful link in the ticket - there's feedback from RAL in the ticket too. Is it just fairshare (fairly) stopping na62 jobs running as quickly as they'd like? In progress (27/9)

BRUNEL
130742 (26/9)
LHCB noticing pilots failing at Brunel - Raul points out that the CE is being replaced so the problems should be going away. In progress (26/9)

130263 (28/8)
Biomed ticket about negative running jobs being published at Brunel - the ARC devs are involved and Raul has kindly offered to test what they have. Any news from them? In progress (13/9)

TIER 1
128991 (16/6)
Solidexperiment.org tape support. The Castor tape is reading for testing, just waiting on word from the VO (aka Janusz). But Janusz is busy in a control room somewhere... Waiting for reply (13/9)

130467 (10/9)
CMS SAM tests failing at RAL, due to a lack of space on CASTOR. Chris has identified a bunch of dark data and set about purging it, ready for another round of consistency checks. In Progress (25/9)

130782 (27/9)
A request from lhcb to deploy the latest version of heposlibs (which contains a dependency on git). The request has been passed along at the Tier 1. In progress (28/9)

130193 (23/8)
CMS staging of files taking a too long from RAL tape- possibly due to a bunch of corrupt files (although manual copies for some problem files are working). George has asked CMS to try again, and if problems persist send a list of dodgy files. Waiting for reply (29/9)

130207 (24/8)
MICE seeing timeouts copying to CASTOR. Gareth provided an indepth update in the ticket, the ticket is being kept open whilst the GenTape disk pool is upgraded. In progress (6/9)

127597 (7/4)
A CMS ticket to check networking and xroot performance, held up for a while waiting on the RAL networking team. There is some recent movement to repoke the networkers. On hold (2/10)

124876 (7/11/16)
ECHO SAM tests failing due to a problem with the tests - no movement on the counter-ticket (125026) since April - it likely needs a kick. On hold (1/1)

117683 (18/11/15)
Getting GLUE 2 working for CASTOR. Intermittently worked on as time allows. The ticket could do with an update this quarter. On hold (6/7)

Tuesday 18th July

• Following our ops discussion last week, Steve will focus his tests on supporting the GridPP DIRAC area and decommission the other tests.
