42 Open UK Tickets this month.

SUSSEX
131617 (3/11/17)
Only this IPv6 ticket at Sussex. End of August was the timescale for the IPv6 rollout given in the network planning document. How's that looking? In progress (4/6)

RALPP
136259 (20/7)
A t2k.org ticket with the user having some trouble with downloading files using the gfal tools. Chris gave some tips but no news from the user side. Any luck finding out what was up with the bdii info? If that seems sorted I reckon this ticket can be closed. In progress (20/7)

131616 (3/11)
RALPP's IPv6 ticket. This poor chap seems neglected and really could do with an update, or putting out of its misery. In progress (16/1)

OXFORD
131615 (3/11)
Again only the v6 ticket for Oxford. Kashif provided a recent (although sadly not very positive) update. On hold (13/7)

CAMBRIDGE
131614 (3/11/17)
Another v6 ticket, at last update (in June) John was waiting on the University to migrate to a new v6 block. Any news on this? No worries if there's not. On hold (5/6)

BRISTOL
131613 (3/11/17)
Yet another v6 ticket, in an update that was only last month Winnie restated the Bristol position, which is the unique state of having dual-stacked all the "hard stuff" and are just waiting to be able to v6-ify the perfsonar. On hold (16/7)

BIRMINGHAM
129930 (4/8/17)
The atlas ticket that heralded the "Dawn of EOS" at Birmingham. I believe that there is work going on towards getting EOS working for atlas at the site, but I see no updates in the ticket.... Just hinting. On hold (23/4)

131612 [(3/11/17)
And Birmingham's v6 ticket. Some postive(ish) news, with Mark waiting on the v6 DNS entries for the perfsonar. Any joy getting that done? On hold (28/5)

GLASGOW
134689 (23/4)
A request from Duncan to upgrade the site's perfsonar to CentOS7. Gareth was waiting on 4.1 to be released first - which at last check (29th June) was only in beta. On hold (24/4)

131611 (3/11/17)
v6 ticket. I don't really want to ask how it's all going... On hold (26/2)

EDINGBURGH
136391 (26/7)
Atlas jobs failing at ECDF-RDF with lcg-cp not found. It appears that there's some confusion in the site's AGIS configs, Teng has asked last week for some changes which he thinks need to be made. In progress (6/8)

131610 (3/11/17)
The ECDF IPv6 ticket. After a promising start the ticket is on hold waiting on updates from the networking team. On hold (21/5)

DURHAM
134687 (23/4)
Durham's request to update their perfsonar, they've adopted the Glasgow position on this matter, but might end up updated "by accident". In progress (3/7)

131609 (3/11/17)
And Durham's v6 ticket. In a recent update there was sadly no positive progress. In progress (10/7)

SHEFFIELD
136014 (10/7)
Atlas transfer errors at Sheffield. Elena cleaned the database, but although things looked better her end atlas still report troubles. I'm reminded of this setup hint that might help (setting control_idle_timeout to 7200). In progress (6/8)

136043 (11/7)
ROD low availability ticket. On hold (11/7)

131608 (3/11/17)
As you may have guessed, the Sheffield v6 ticket. Elena gave an update last month, although sadly the news wasn't very positive. On hold (10/7)

MANCHESTER
136631 (9/8)
Atlas seeing deletion errors. Alessandra has had to kick things a few times but things were looking good this morning. In progress (13/8)

131607 (7/11/17)
Manchester's v6 ticket. Perfsonar is v6'd, but IIRC it might be a while until the SE is dual-stacked due to v6 DNS issues. Any progress with this from your Central IT people? On hold (14/5)

LIVERPOOL
136667 (12/8)
Atlas deletion error ticket. John is away, but my recommendation is just check you have httpd running on all your pool nodes. In progress (13/8)

131606 (3/11/17)
The Liverpool v6 ticket. At last check not a sausage was to be heard about the new routers that will sort out the v6 performance issues seen by the site. In progress (4/6)

LANCASTER
136648 (10/8)
Atlas transfer ticket for Lancaster as the site recovers from a DPM headnode migration that was a little rough (to say the least). We might have fixed things (or at least made things less bad). In progress (13/8)

136635 (9/8)
ROD Availability ticket, another side effect of the DPM migration. On hold (9/8)

UCL
134686 (23/4)
Request to upgrade the site perfsonar hosts to C7. No news on this at all. On hold (23/4)

131604 (3/11/17)
UCL's v6 ticket. In a May update Ben noted he had re-poked UCL Networks. No news since - has anyone heard from Ben about anything? Just checking he's okay down there. On hold (4/5)

RHUL
131603 (3/11/17)
The only ticket for RHUL is their v6 ticket. Now that you are Post-Govind how are the site's v6 plans looking? In progress (6/2)

QMUL
136550 (4/8)
A ticket from t2k that I only just noticed didn't have the "notify site" field filled in. The user was having SE connection problems, but I think this coincided with other problems at the site, so maybe the issue is fixed now? Again the same user is seeing bdii problems in his gfal commands. Assigned (13/8)

136178 (17/7)
A kind of parent ticket to the above one, here the same t2k user was seeing timeout issues. The situation seems a little confusing. In progress (7/8)

136576 (13/8/0647)
Availability ticket after the aircon failures. On hold (6/8)

136641 (9/8)
Atlas transfer failures after some load problems. Following the link it looks like the issues are cleared up for the last 48 hours. Dan notes in the ticket that QM might need to buy a new Storm headnode next time out. In progress (11/8)

134573 (17/4)
Request from CMS to install singularity. Planned for the end of Summer move to C7. Any news on that? On hold (17/4)

132929 (18/1)
Problems with APEL at QM. No news in the ticket since May. In progress (10/5)

BRUNEL
133956 (9/3)
Changing the CMS xroot config ticket. Raul is postponing the work until the move to C7/dome. In progress (3/7)

136649 (10/8)
CMS notes some possible missing files at Brunel, which Raul cannot find a record for in the last 4 weeks. Raul has asked for some extra details, as they've had phantom files at the site before. In progress (13/8)

TIER 1
136199 (18/7)
LHCB are seeing a lot of stuck transfers on the RAL FTS. In progress (7/8)

136655 (10/8)
LHCB spotted a missing file (with no replicas) at RAL. Sadly the file was dead, so I think this ticket can be closed. In progress (13/8)

136028 (10/7)
A CMS ticket with troubles reading files off of RAL disk - which I think are due to xroot problems (it's a very long ticket and I only had tiem to skim it). Chris has asked if there's a CMSSW expert that they can get involved. In progress (13/8)

136358 (25/7)
CMS xroot access problems from the RAL WN. On hold whilst other issues are cleared up. On hold (13/8)

136563 (6/8)
CMS spotted possibly corrupt files at RAL, the ticket has been referred to the ECHO team, but that was a week ago now. Of course there have been problems... In progress (6/8)

136665 (11/8)
CMS ticket for the site being down, the ticket is referred to the unscheduled downtime and other issues. In progress (12/8)

136366 (25/7)
A ticket from MICE asking for them to be removed from the batch system at RAL as the experiment winds down. Catalin asks if the removal can be tested to see if it fails as it should. Waiting for reply (8/8)

124876 (7/11/16)
The old Ops gridftp test ticket for ECHO. Waiting on a change to be rolled out to the RAL WNs to get the new tests working. In progress (28/6)
