Tuesday 9th May
Tuesday 4th April
- The next ops coordination meeting is this Thursday 6th April. Agenda. The theme is HTCondor accounting work at PIC.
- Any T1 or T2 issues to be discussed?
Monday 20th March
Monday 6th March
- There was an ops coordination meeting on Thursday 2nd March - agenda | Minutes.
- The overview talks were: Mid-SLAs | Machine Job Features.
- The main summary items:
- Lessons learned from ATLAS tape usage tests. Follow up via FTS steering group. Will share experience with other experiments.
- "Mid SLA" resources. During the next months accumulate experience at CERN (providing such resources) and in experiments (using such resources). Review accumulated experience after a couple of months and decide what we need to do in terms of tagging, accounting, etc...
- MJF deployment is not as successful as desired. Find help (at least temporary) for deployment campaign concentrating on the LHCb sites. See whether this task would become more important considering outcome of the benchmarking discussion.
- In order to avoid inconsistencies in the naming of the service types along the WLCG IS chain (GocDB, OIM, SAM, experiment-specific systems like Dirac), there will be agreement between representatives from OSG, EGI and GocDB team and IS evolution task force on the policy for introducing of the new service types.
- The next WLCG ops coordination meeting will be on 6th April.

Tuesday 16th May
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- Castor central services were upgraded to version 2.1.16 on Tuesday 9th May. It was not possible to do the LHCb stager and SRMs the same day and this is being on done Thursday (11th). Remaining updates to bring the rest of Castor to this version likely to be in around two weeks time.
- As reported for last week's meeting: On Friday 28th April there was a problem with the UPS for building R89. The UPS switched itself into "bypass" mode - which effectively means we have no UPS. We have run in this way since then. The cause was overheating of internal capacitors which failed. A new UPS has been installed and it is being commissioned. In the current situation the diesel generator cannot be used.
- The new version of FTS3, installed on our "test" FTS service (used by Atlas) last week no longer supports the SOAP API. There are still some access to our "production" FTS3 service via this API (mainly SNO+ and MICE). We will wish to upgrade the production FTS3 srevice - and need VOs to move to the rest API provided with the newer versions of FTS. Would like to set deadline when we upgrade the "production" instance and hence no longer support the SOAP API.

34 Open UK Tickets this week - we're whittling them down.
Merseyside Webdav Access
128328 (15/5)
The Liver Lads got a ticket concerning Liverpool's information in the gocdb and how it was lacking a webdav endpoint. I'm not sure DPMs explicitly have a https://<hostname>443/webdav/<vo? endpoint, and webdav access just used the same namespace as everything else. But I could be wrong. Steve was on it though. In progress (15/5)
Sneaky Ticket at ECDF
128294 (12/5)
This ROD availability ticket snuck in on Friday and looks like it hasn't been noticed yet. Assigned (12/5)
Also regarding the SE ticket 128129 - we've been bitten by similar sounding issues at Lancaster, our SE was looking really clogged up and service restarts weren't cutting it - we had to reboot which seemed to cheer everything up.
And regarding the perfsonar ticket 127940, we had the same error message was was fixed by sorting out IPv6 for the node which had gotten into a weird state. Not sure if that applies though.
UK XROOTD Redirector at RAL
127598 (7/4)
Andrew reports that the machine to host this service is installed and awaiting firewall holes. Nice. In progress (12/5)
THANKS TO DANIELA AND DAN for helping Sussex out.
122772 (11/7/16)
Webdav/xroot ticket - atlas have enabled webdav and I assume it's working for them. In progress (9/5)
125503 (9/12/16)
Sno+ troubles after Sussex SE renaming- Daniela has been helping out and devising an LFC renaming strategy. Waiting for reply (10/5)
