47 Open UK Tickets this month.
 
 
'''SUSSEX'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131617 131617] (3/11/17)<br />
 
The site's IPv6 ticket. Good news from Leo today, with all external services dual-stacked (the perfsonar just needs adding to the mesh). Nice one! Waiting for reply (3/9)
 
 
'''RALPP'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136958 136958] (30/8)<br />
 
t2k had their replications to ralpp timing out, but Chris noticed that they've run out of space. He's kindly trying to free them up a bit more room. In progress (31/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136927 136927] (29/8)<br />
 
CMS transfer failures, which look to be due to a bad file. It's been invalidated and a proper replica moved to the site. This should be just about done with? In progress (30/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131616 131616] (3/11/17)<br />
 
RALPP v6 ticket. Any updates? In progress (16/1)
 
 
'''OXFORD'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131615 131615] (3/11/17)<br />
 
Oxford's v6 ticket. Last update was July, I suspect there's been no progress over the summer. On hold (13/7)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136687 136687] (13/8)<br />
 
A bit of an odd LHCB FTS ticket as it's intended to mirror the issure for a site rather then track an issue at a site. From my understanding these are known issues with third party http transfers? In progress (17/8)
 
 
'''CAMBRIDGE'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131614 131614] (3/11/17)<br />
 
Cambridge's v6 ticket. Last update was back in June, any more news on the move to a new address block? On hold (5/6)
 
 
'''BRISTOL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131613 131613] (3/11/17)<br />
 
And Bristol's v6 ticket. Winnie's kept us appraised of the situation back in July. On hold (16/7)
 
 
'''BIRMINGHAM'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=129930 129930] (4/8/17)<br />
 
The http ticket that kind of tracks the move to EOS now. I do wonder if it's worth keeping this ticket around much anymore, as there's an epic Jira ticket charting the migration. On hold (14/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131612 131612] (3/11/17)<br />
 
The Birmingham v6 ticket. Mark gave some not great news last month. Andrea has asked to turn up the pressure. Maybe we can help? On hold (27/8)
 
 
'''GLASGOW'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=134689 134689] (23/4)<br />
 
Request to upgrade perfsonar to C7. Perfsonar 4.1 is out now if you feel like revisiting this. On hold (14/8) ''Update - Gareth has come up with some questions for Duncan about how best to go about setting up a perfsonar for the mesh. Waiting for reply.''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131611 131611] (3/11/17)<br />
 
Glasgow's v6 ticket. Any new (aspirational) plans that need to go into the ticket? On hold (26/2)
 
 
'''ECDF'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131610 131610] (3/11/17)<br />
 
Just the old v6 ticket at ECDF. Any news since your misadventures back in May? On hold (28/5)
 
 
'''DURHAM'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136909 136909] (28/8)<br />
 
Atlas deletion error ticket. The Durham guys are just back in the office and poking the ticket. In progress (3/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=134687 134687] (23/4)<br />
 
The other outstanding request to upgrade the perfsonar host. In progress (14/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131609 131609] (3/11/17)<br />
 
Durham's v6 ticket. From the feel of the July update I'm going to hazard a guess that there's not been any recent progress. In progress (should be On Hold?) (10/7)
 
 
'''SHEFFIELD'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136014 136014] (10/7)<br />
 
Atlas transfer errors, evolved to problems with the error message "job has been canceled because it stayed in the queue for too long". As this an FTS side error? Perhaps the SE is simply being overworked? In progress (30/8) ''Update - Elena reports that after some DPM config changes efficiency is up to 73%''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131608 131608] (3/11/17)<br />
 
Sheffield's v6 ticket. How goes the work that was supposed to resume in July? On hold (10/7)
 
 
'''MANCHESTER'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136976 136976] (1/9)<br />
 
A fresh atlas transfer error ticket. Robert found that their DPM's mysql database wasn't responding, but a restart should have fixed it (and indeed a peek at the monitoring shows this to be the case). In progress (1/9) ''Update - solved with transfers at 100% again.''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131607 131607] (3/11/17)<br />
 
Manchester's v6 ticket. Any news on this since the April update? On hold (24/4)
 
 
'''LIVERPOOL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131606 131606] (3/11/17)<br />
 
Just the v6 ticket at Liverpool. Any news since the June update? In progress (4/6)
 
 
'''LANCASTER'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136793 136793] (20/8)<br />
 
A ticket from snoplus as the Lancaster SE wasn't in the cern bdii. It looks like none of the Lancaster resources are in the cern bdii, even though other top bdiis know about this. A bit of a head scratcher. Has anyone else been "censored" (or censured) by the CERN bdii? In progress (3/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136635 136635] (9/8)<br />
 
A low availability ticket, not too far off being able to close it. On hold (9/8)
 
 
'''UCL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=134686 134686] (23/4)<br />
 
Request to upgrade perfsonar. No news since the ticket was acknowledged. On hold (23/4)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131604 131604] (3/11/17)<br />
 
UCL's v6 ticket. There was a re-poking of the network team back in May but no news since. On hold (4/5)
 
 
'''RHUL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=131603 131603] (3/11/17)<br />
 
Just the v6 ticket at Royal Holloway. How's it going? It looks like lack of v6 DNS was the problem here again. In progress (perhaps should be On Hold?) (6/2)
 
 
'''QMUL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136719 136719] (15/8)<br />
 
LHCB having file access problems (again?). Daniel thought it might be the SE misbehaving under load that's causing the problems. There was some testing, but I'm not sure of the conclusion. Waiting for reply (23/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136550 136550] (4/8)<br />
 
t2k having file access problems, with the root cause being the top bdii they were using being broken (sounds similar to what Lancaster has been seeing). It looks like the problem has gone away here though, so I think this ticket can be closed. In progress (14/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136714 136714] (14/8)<br />
 
The same t2k user having problems reliably copying files, but again this issue seems fixed. In progress (15/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136918 136918] (28/8)<br />
 
t2k not noticing downtime notices. It looks like this ticket can be closed too. In progress (3/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136178 136178] (17/7)<br />
 
It's a seemingly solved t2k ticket at Queen Mary that hasn't been closed by the user. You don't see many of those around. In progress (14/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136712 136712] (14/8)<br />
 
LHCB noticed they weren't running (many) jobs at QM. Dan explained why (all very reasonable). It looks to me this ticket is resolved. In progress (14/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136576 136576] (6/8)<br />
 
A low-availability ROD ticket after the cooling troubles. The A/R numbers are almost up to par. On hold (6/8) ''Update - closed by Kashif with his ROD hat on.''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=132929 132929] (18/1)<br />
 
APEL accounting for slurm ticket. Dan has been working on this, and has spread the new accounting scripts around his CEs and APEL box. In progress (3/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=134573 134573] (17/4)<br />
 
Request from CMS to install singularity. Dan has it on his to do list, is the move to C7 still planned for the end of the Summer (i.e. soonish)? On hold (17/4)
 
 
'''BRUNEL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136806 136806] (21/8)<br />
 
CMS jobs having problems at Brunel. There was an interesting case where WNs lost v4 connectivty whilst maintaining v6 and this were still able to get jobs, but the root cause looks to be problems with the xroot fallback mechanism. I think this might be above the site's metaphorical paygrade. In progress (31/8) ''Update - it's looking like the site-side issues are solved, just waiting on one last round of checks.''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=133956 133956] (9/3)<br />
 
A CMS ticket to reconfigure the site's xrootd configs. Postponed due to waiting on a move to C7/DOME. Have you made any progress with this? FYI we're planning on turning DOME on at Lancaster soonish. In progress (3/7)
 
 
'''TIER 1'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136884 136884] (27/8)<br />
 
lcg-cr not working for t2k, an lfc ticket that's been ported over to RAL as it looks like their database is corrupted. In progress (29/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136840 136840] (23/8)<br />
 
A Sno+ ticket, which looks to be related to the LFC issues. In progress (29/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136942 136942] (29/8)<br />
 
t2k noticing timeouts copying ONLINE_AND_NEARLINE files at RAL. After investigation it lead to the RALPP ticket above, and this ticket was left unclosed. In progress (can be closed) (30/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136701 136701] (14/8)<br />
 
LHCB would like to investigate the high background failure rate of jobs transferring their data out at RAL. A lot of back and forth on the ticket. Waiting for reply (3/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136967 136967] (31/8)<br />
 
CMS Phedex transfers from RAL to FNAL failing. Checking on it has been passed to the ECHO team. In progress (31/8) ''Update- solved after some files were declared lost.''
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136366 136366] (25/7)<br />
 
Removing MICE from the batch queues. It looks like submission has been successfully disabled. In progress (20/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136757 136757] (17/8)<br />
 
MICE VO voms configs missing from the LFC. This looks to be fixed (although the suspected database problems might interfere with stuff). In progress (21/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136028 136028] (10/7)<br />
 
CMS have issues reading files on ECHO, which looks to be a xroot problem (I couldn't follow the ticket). Chris B has put a lot of effort into this, and Brian Bockelman is roped into the ticket now. In progress (29/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=136199 136199] (18/7)<br />
 
An LHCB ticket to the FTS team, progress on the ticket stalled nearly a month ago (have people been on holiday?). In progress (7/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=124876 124876] (17/11/16)<br />
 
Getting ECHO gridftp ROD tests working. Things were looking quite good, but it looks like the ticket is waiting on a WN config change to be rolled out at RAL still? The tests are still broken. In progress (23/7)

Tier-1 - Status Page

Tue 14th August Report for the Experiments Liaison Report (13/08/2018) is here.

  • Tier-1 at RAL have had an unscheduled outage for Echo since Friday evening (10/8/18). The initial cause of this issue is thought to be a combination of client I/O and cluster I/O (moving data onto new hardware), which is causing an excessive amount of memory usage. This in turn is causing machines to start swapping heavily, which is placing even more load on the cluster. This has necessitated pausing all I/O operations on the cluster to try and reduce memory usage while we are restoring the cluster to a healthy state, and putting measures in place to reduce the memory usage on the storage nodes.
  • While this investigation and work is carried out the ongoing downtime has been extended until 12:00 16/08/2018
