** The LFC is STILL running - hurrah! We now believe that this problem has been correctly resolved.

* FTS / gfal version issues
+
**The newest version of gfal made changes to the way certificate are processedThis broke transfers to a significant number of sites.  Tier-1 was ticketed to role back the FTS service.
+
* New Castor tape service:
+
** Teir-1 have successfully run ATLAS performance tape test.  Excellent results at 2GB/s.  This was reported at the WLCG Archival Storage WG[1].   
+
** We were second only to IN2P3 who got 50% better throughput but had dedicated 36 T10KD drives compared to our 8 T10KD drives.   
+
** As we migrate more VOs to the new Castor instance we will have more drives available (up to 22) and this should mean we are likely to double our overall throughput.

 +
* Three certificates were revoked mistakenly on ARGUS on Thursday.  All SAM tests failed until this was fixed the next morning.  Batch farm also did not start any new jobs during this time.  We used this accidental draining to reboot nodes that needed to pick up security patching.
 +
* LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
 +
* Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team.  Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

LHCb has added this to their requirements:
* Changes to Approved VOs: LZ record at Imperial now showing up in the portal (had been inserted as a special case until now.)
+
  
 +
Sites not having an SRM installation must provide:
  
'''Tuesday 11th June 2018'''
+
* disk only storage
 +
* a GRIDFPT endpoint (a single dns entry)
 +
* an XROOT endpoint (a single dns entry)

''' Tue 16th April 2019'''
  
'''Tuesday 11th June 2018'''
+
Minor change to LHCB requirements in Approved VOs:
  
Approved VOs now contains two new SKA VOMS servers (at Oxford and Imperial, as well as Manchester).
+
* Sites having migrated to the Centos7 (including "Cern Centos7") operating system or  later versions are requested to provide support for singularity containers.

 +
 +
'''Tue 2nd April 2019'''
 +
 +
Changes to Approved for DUNE (and LZ)
 +
 +
There is a new "Approved VOs" document showing new settings for DUNE. And, since both LZ's voms servers now show up in the EGI Portal, I've removed the (now spurious) entry for voms.hep.wisc.edu that was formerly being inserted by hand.
 +
 +
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
 +
 +
I've also created a new set of RPMs (each has all LSC, VOMS, and XML for one VO) for all approved VOs. See Approved VOs doc for details, version is 1.9.
 +
 +
Sites with DUNE services need to update using whatever method they employ.
 +
 +
Special note: Since voms1.fnal.gov changed yesterday, I've updated documentation for that right away. But voms2.fnal.gov remains as it is until 23rd April (3 weeks). I'll update documentation for that when it is closer. Staggering the updates like this gives a time margin, so any particular site can have at least one service properly configured at any time.  But it does mean that two site updates are needed; one now, and one in three weeks. However, since it's sufficient for only one (of the two) voms servers to be configured properly, sites could save effort and wait until (say) 19th April, then update both at once. But I can't dictate what site admins should do. It's your call.

* Dashboard struggled during the week and it was slow but now it seems to be OK.
 
* One Bristol ticket got stuck in weird state where it can not be deleted from dashboard although it has been solved.
 
 
'''Monday 21st May'''
 
* There was a problem with jobs accessing  http://repository.egi.eu:80/sw/production/cas/1/current/meta/ca-policy-egi-core.list to get the latest release so many arc ce test fails. No tickets opened for these alarms and the problem went away when the underlying issue was fixed.

42 Open UK Tickets this month.
 
 
'''IPv6 Tickets'''<br />
 
'''BRISTOL:''' https://ggus.eu/?mode=ticket_info&ticket_id=131613<br />
 
Last update 4/10. There is some recent conversation of this ticket, servers are v6 configured but things are not quite right - perhaps with the v6 routing?
 
 
'''UCL:''' https://ggus.eu/?mode=ticket_info&ticket_id=131604<br />
 
Last update 4/10. Some positive news with hopefully some v6 addresses rolling out soon - but that old bugbear of v6 DNS being a problem is showing up again. Ben finishes his update asking if firewall rules remain the same between v6 and v4.
 
 
'''DURHAM:''' https://ggus.eu/?mode=ticket_info&ticket_id=131609<br />
 
Last update 10/7. Any news on this front? There seemed to be a lot of exasperation in the last, short post back in July.
 
 
'''CAMBRIDGE:''' https://ggus.eu/?mode=ticket_info&ticket_id=131614<br />
 
Last update 25/9. Some good news here, with the Cambridge perfsonars dualstacked and added to the mesh. Duncan noticed some low throughputs for the v6 traffic, but they are otherwise working.
 
 
'''BIRMINGHAM:''' https://ggus.eu/?mode=ticket_info&ticket_id=131612<br />
 
Last update 27/8. At the last update in August Mark mentioned that their Central I.T. was waiting on some shiny new infrastructure before they could provide v6 DNS. Has a timescale on getting this rolled out appeared in the last 6 weeks? Pressure definitely needs to be applied I think.
 
 
'''LIVERPOOL:''' https://ggus.eu/?mode=ticket_info&ticket_id=131606<br />
 
Last update 4/6. Steve and Co were waiting on new switches so that their v6 performance wouldn't be terrible, plus there were internal negotiations going on. Any news on any of this?
 
 
'''RHUL:''' https://ggus.eu/?mode=ticket_info&ticket_id=131603<br />
 
Last update 10/9 (from Duncan). Any news at all on this? The perfsonar was dual-stacked but as Duncan pointed out no v6 DNS.
 
 
'''OXFORD:''' https://ggus.eu/?mode=ticket_info&ticket_id=131615<br />
 
Last update 13/7. Kashif once again mentioned v6 DNS and a blocker. Any progress pressuring them?
 
 
'''GLASGOW:''' https://ggus.eu/?mode=ticket_info&ticket_id=131611<br />
 
Last update 4/9. It's not been that long since your last update where your move to Plan B (or is it Plan C, D, or Z?) was mentioned. Any news in that short space of time?
 
 
'''RALPP:''' https://ggus.eu/?mode=ticket_info&ticket_id=131616<br />
 
Last (proper) update 16/1. Any news here? Things seemed really positive for a while, but that was 2 seasons ago. Really needs an update.
 
 
'''MANCHESTER:''' https://ggus.eu/?mode=ticket_info&ticket_id=131607<br />
 
Last (proper) update 25/4. The perfsonars are dualstacked, but no news on the storage (again due to v6 DNS problems IIRC). Another ticket that really needs any update?
 
 
'''ECDF:''' https://ggus.eu/?mode=ticket_info&ticket_id=131610<br />
 
Last update: 6/9. There have been some Ipv6 misadventures at ECDF, but a lot of effort has been put into getting things working. Any luck on getting your pool nodes dualstacked (or finding out when you'll be able to do this)?
 
 
'''SHEFFIELD:''' https://ggus.eu/?mode=ticket_info&ticket_id=131608<br />
 
Last update 10/7. Things were looking up for a while in the last update, but I take it from the silence since things haven't made much progress?
 
 
Back to the regular tickets, site-by-site as is the tradition.
 
 
'''RALPP'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137633 (8/10)<br />
 
A very fresh CMS ticket for transfer failures to RALPP. Assigned (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137361 (24/9)<br />
 
A t2k ticket, where a user notices that you can upload a zero-sized file but you cannot then download it. I'm not sure why this is relevant, but Chris can replicate with the Imperial SE and reckons it's a dcache "feature". It might be that this will go unresolved. In progress (26/9)
 
 
'''GLASGOW'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=134689 (23/4)<br />
 
Request to upgrade the Glasgow perfsonars. With the release of 4.1 Gareth is working on it, and would like to build the new perfsonars using the docker images. Duncan has suggested giving it a go with the perfsonar-testpoint image to see how things go. In progress (21/9)
 
 
'''ECDF'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137627 (8/8)<br />
 
A ROD ticket for failed SRM tests, Rob notes likely caused by some storages on a disk server falling over. Being fixed (and indeed the tests are working now). In progress (8/8)
 
 
'''DURHAM'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=134687 (23/4)<br />
 
The Durham request to upgrade perfsonar. Adam has put upgrading onto their todo list in the last update. In progress (26/9)
 
 
'''SHEFFIELD'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137491 (1/10)<br />
 
Atlas transfer failures to Sheffield. Acknowledged by the site, but have you had any luck tackling the issue? From today's update by the DDM shifters it looks like it's ongoing. In progress (8/10)
 
 
'''MANCHESTER'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137112 (11/9)<br />
 
Atlas spotted that SRM space reporting at Manchester was broken. Robert set them straight- it was due to a bug in a draining script moving data outside of the tokens. Fixing this is a slow process, Robert estimated of the order of weeks. On hold (20/9)
 
 
'''LIVERPOOL'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137458 (28/9)<br />
 
Liverpool's SE not working for biomed, due to there being no space left on the communal area. Liverpool have a spacetoken for biomed, but it was going unused. John and Stephan helped the VO with how to query these. I suspect this ticket can be closed soon. In progress (4/10)
 
 
'''LANCASTER'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=136635 (9/8)<br />
 
Low availability ticket for Lancaster. Being tough to get a clear 30 days due to a collection of downtimes and the Lancaster SE playing up a bit. On hold (8/10)
 
 
'''QMUL'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=132929 (18/1)<br />
 
APEL accounting ticket for QM's slurm batch system. Lots of discussion and a related APEL ticket (https://ggus.eu/index.php?mode=ticket_info&ticket_id=118969). I'm not sure if there's much further input to be had from the site for now? In progress (12/9)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137180 (13/9)<br />
 
A t2k ticket complaining about the QM data access being slow. One of several tickets tackling a known issue with the QMUL STORM (particularly SRM). Dan helpfully provided a bunch of alternatives and suggestions to help the user - so useful it should be documented! In progress (14/9)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137631 (8/10)<br />
 
A fresh ROD ticket - all SE based tests... Assigned (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=136719 (15/8)<br />
 
LHCB having file access problems at QM (although I think file metadata access problems would be more exact). The ticket mentions a database move, did you get round to this? In progress (18/9)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137622 (8/10)<br />
 
LHCB FTS transfer problems - Dan notes that a rack had power problems which required physical intervention. The rack is back on so hopefully transfers will work again. In progress (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137617 (7/10)<br />
 
An atlas ticket for the same issues. In progress (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=134573 (17/4)<br />
 
A request to install singularity from CMS. Dan mentioned right at the start that this would be part of their CentOS7 move. Is this on the horizon? On hold (17/4)
 
 
'''IMPERIAL'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137468 (28/9)<br />
 
CMS production job stage outs from Brunel to I.C. failing. Daniela cannot reproduce this by hand even though the problems persist for CMS. An environment to test this out by hand has been provided so Raul could try it out on a WN directly. In progress (5/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137352 (24/9)<br />
 
CMS noticed a few transfers failing - a pool node had fallen over and then had filesystem troubles. All fixed now, so we're in the wait and see if things go green stage. Waiting for reply (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=136687 (28/9)<br />
 
Loosely related to 137468 (this ticket uncovered that issue), CMS stageout failures at Brunel. I didn't quite follow the thread, but diagnostics were being run over the weekend. Did they reveal anything? In progress (5/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137451 (28/9)<br />
 
LHCB data transfer problems at Brunel. A lack of information had made Raul's job debugging this difficult. Vladimir responded with something that could help a bit today. In progress (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=133956 (9/3)<br />
 
CMS xroot config change ticket. In July a multi-point plan was laid out, how goes it? In progress (3/7)
 
 
'''100IT''' have a ticket: https://ggus.eu/?mode=ticket_info&ticket_id=137306
 
 
'''Orphaned ticket:''' https://ggus.eu/?mode=ticket_info&ticket_id=136687<br />
 
I think this ticket regarding third party http transfers and the FTS can be closed, I'm not sure anyone's looking at it.
 
 
'''THE TIER 1'''<br />
 
https://ggus.eu/?mode=ticket_info&ticket_id=137195 (14/9)<br />
 
A ROD ticket due to bdii problems causing SRM test failures. The issues are known about and being worked through, but at last check on Friday the problems persist. In progress (5/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137391 (25/9)<br />
 
Atlas seeing poor transfer efficiency to tape and disk at RAL. Tim narrowed the errors down to a pair of sources. One of the sources (TRIUMF) has spotted the cause at their side (a v6 networking issue I failed to fully understand), it may or may not be a similar problem for EELA-UTFSM. In progress (5/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=136701 (14/8)<br />
 
LHCB noticing a high (5%) background failure rate for jobs at RAL. The theory is a network issue or a problem with Castor. Waiting on the submitter to get back from his hols. Waiting for reply (24/9)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=136199 (18/7)<br />
 
LHCB stuck FTS transfers. There's been a long break in looking at this, waiting on Catalin to get back from a well-earned break. On hold (1/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137153 (12/9)<br />
 
A t2k ticket about 0-sized files, asking how to deal with them in the LFC (where they seem to have a bunch of these). It appears to be unrelated to the recent LFC issues. There's some discussion at the Tier 1 about what to do. In progress (25/9)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=137634 (8/10)<br />
 
A fresh CMS ticket regarding some transfer failures to METU (although the error could be at either end). In progress (8/10)
 
 
https://ggus.eu/?mode=ticket_info&ticket_id=124876 (7/11/16)<br />
 
The old ECHO gridftp test ticket - it's looking now like a simple authorisation problem for the test's robot certificate - so maybe we're nearly there fixing this. In progress (8/10)
 
 
  
 +
32 Open Tickets this week, which is an in depth a look as I've been able to take.

WLCG Operations Coordination - AgendasWiki Page

Tuesday 11th June

  • I got stuck (figuratively) in my machine room last Thursday afternoon so missed it. Agenda. Minutes. Ste was there - any observations?

Tuesday 14th May

  • Next meeting this Thursday.

Tuesday 9th April


Tuesday 26th March

Monday 11th February 2019

  • There was a WLCG ops coordination meeting last Thursday. You can view the meeting notes here.
    • End of CREAM support Dec 2020.
    • Migration from CREAM to be discussed at the EGI conference 6-8 of May in Amsterdam.
    • Operational intelligence discussion (see slides).
    • Experiment updates (see ATLAS discussion on DOMA)
    • WG updates (few).




Tier-1 - Status Page

17 June 2019 Report for the Experiments Liaison Report (17/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.

11 June 2019 Report for the Experiments Liaison Report (10/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.
  • Three certificates were revoked mistakenly on ARGUS on Thursday. All SAM tests failed until this was fixed the next morning. Batch farm also did not start any new jobs during this time. We used this accidental draining to reboot nodes that needed to pick up security patching.
  • LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
  • Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team. Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

Documentation - KeyDocs

Tue 9th July 2019

LHCb has added this to their requirements:

Sites not having an SRM installation must provide:

Tue 16th April 2019

Minor change to LHCB requirements in Approved VOs:

  • Sites having migrated to the Centos7 (including "Cern Centos7") operating system or later versions are requested to provide support for singularity containers.

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

Tue 2nd April 2019

Changes to Approved for DUNE (and LZ)

There is a new "Approved VOs" document showing new settings for DUNE. And, since both LZ's voms servers now show up in the EGI Portal, I've removed the (now spurious) entry for voms.hep.wisc.edu that was formerly being inserted by hand.

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

I've also created a new set of RPMs (each has all LSC, VOMS, and XML for one VO) for all approved VOs. See Approved VOs doc for details, version is 1.9.

Sites with DUNE services need to update using whatever method they employ.

Special note: Since voms1.fnal.gov changed yesterday, I've updated documentation for that right away. But voms2.fnal.gov remains as it is until 23rd April (3 weeks). I'll update documentation for that when it is closer. Staggering the updates like this gives a time margin, so any particular site can have at least one service properly configured at any time. But it does mean that two site updates are needed; one now, and one in three weeks. However, since it's sufficient for only one (of the two) voms servers to be configured properly, sites could save effort and wait until (say) 19th April, then update both at once. But I can't dictate what site admins should do. It's your call.
