| − | 28 Open UK Tickets today.<br />

| | | | |
| − | '''NGI'''<br />
| |
| − | https://ggus.eu/index.php?mode=ticket_info&ticket_id=106057 (9/6)<br />
| |
| − | The creation of a new UK Cloud site UKI-LT2-IC-HEP-Cloud. Jeremy has created the site and I see Adam has signed himself up as an Admin to it. Does anything else need doing? In progress (11/6)

| |
| − | Sno+ ran into a spot of bother with some of the UK vomses, Robert replied with a good explanation of what was going on at Manchester. Something for the other voms sites to watch out for (although you probably know all about it). In progress (is it solved?) (16/6)

| − | '''SUSSEX'''<br />
| |
| − | https://ggus.eu/index.php?mode=ticket_info&ticket_id=106060 (9/6)<br />
| |
| − | Matt RB fixed one atlas problem with the Sussex Storm SE, but another has come along- looking like bad checksums. Wahid suggests asking Chris Walker (the Storm Whisperer) for his advice. In progress (16/6)

| − | https://ggus.eu/index.php?mode=ticket_info&ticket_id=102810 (28/3)<br />
| |
| − | Sussex's EMI ticket - almost done now, I believe the alarms are disappearing and now the problems are with services not working (but as we discussed last week, upgraded and broken is still upgraded!). In progress (13/6)

| − | https://ggus.eu/index.php?mode=ticket_info&ticket_id=105618 (21/5)<br />
| |
| − | Sorry to be picking on Sussex. I suspect this Sno+ cvmfs ticket has been put on the back burner - can it be put on hold until you get round to it. In progress (9/6)

| General updates
|
Monday 23rd June
Monday 16th June
- There was a GDB last week and pre-GDB on IPv6. Of particular interest is Helge's trip report from HEPIX. The official GDB summary notes are now available and the actions updated.
- GGUS ran into problems over the weekend and this affected ticket processing. The system did not recover from a DB connection problem and required a server restart.
- There is a plan for the upgrade of the CVMFS installation servers hosted at CERN from v 2.0 to v 2.1, starting from August the 5th. Before the servers upgrade (by the end of July) there is a request to make sure that the CVMFS clients deployed on the WLCG infrastructure are upgraded to the 2.1.19 version, released on 28th May.
- Well done to Brunel for being the first UK site to offer EGI resources via the eGrant system!

- Machine/job features: SGE implementation now at Imperial.
- M/w readiness: See the task overview.

- We are looking at how to end the FTS2 service, now FTS3 is becoming widely used.
- The software server used by the small VOs will be withdrawn from service. Its use as a software server is very limited (possibly only SNO+) although a few VOs use it for uploading files to the CVMFS repository.

Tuesday 24th June
- An update from Janusz on DIRAC:
- We had a stupid bug in Dirac which affected the gridpp VO and storage. Now it is fixed and I was able to successfully upload a test file to Liverpool and register the file with the DFC
- The async FTS is still under study, there some issues with this.
- I have a link to software to sync user database from a VOMS server, haven’t looked into this in detail yet.
Tuesday 20th May
Between May 1st and May 12th, SAM-CENTRAL and the Message Broker Network have experienced a set of chained failures that resulted in the loss of a large portion of the metric results that were published by the SAM NGI Instances. The loss of these messages will result in an unusually high number of UNKNOWNS in the May A/R reports, but the actual A/R numbers will not be affected as UNKNOWNS are not take into account. No other services have been affected.
Tuesday 13th May
- From last week's discussion DiRAC now supports: NA62, vo.landslides.mossaic.org, t2k.org, snoplus, gridpp, CERN@school and northgrid. NA62 are moving from LFC to DFC and plan to use DiRAC in place of the WMS.
