Experimental Updates

LHCB- nothing to report
CMS- trying to change SAM tests to gfal2 - however this isn't working as well as CMS say - sites shoud look at their results.
https://etf-cms-prod.cern.ch/etf/nagios/
Gareth - we noticed a blip but fixed itself - saw lots of transfers at zero rate.
Daniela advises ignoring this for 24 hours.

Brian - we had a lot of issues with the right version of gfal.
-mentions version in the tarball, but generally thought that's okay.

Pete G sees problems with xrootd test, but Daniela says that is harmless for a Tier 3.

ATLAS - some problems at QM, Dan thinks it's to do with Gridftp on a 1G link. Some problems at Birmingham

Matt D - things are piling up a bit at Birmingham, they should be offered support.

Other VOs - no news

Meetings and Updates

Pre-GDB meeting http://indico.cern.ch/event/394831/
Security Operations Centre Face to Face - David attending.

GDB http://indico.cern.ch/event/394784/
Presentations from David and Ian.

MWR meeting last week - https://twiki.cern.ch/twiki/bin/view/LCG/MWReadinessMeetingNotes20160706
Matt D - mainly CentOs 7 WN and UI talk.

Kashif - from 1st of July Argo takes over monitoring - very simlilar to nagios. Kashif started decommissioning to reduce the number of Ops tests being sent out. VO nagios will be kept running until a replacement comes - not sure how that's going to work. Full decommissioning will starts soon.

Gareth R - are we sure that these are production ready? Seeing lots of source failures? Should we be concerned?
Kashif - Point me to these errors please,
https://argo-mon.egi.cro-ngi.hr/nagios/cgi-bin/status.cgi?host=svr019.gla.scotgrid.ac.uk&servicestatustypes=16&hoststatustypes=15&serviceprops=0&hostprops=0

Gareth - Red for 4 days, stage in failures. See similar error in argomon2
https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?host=svr019.gla.scotgrid.ac.uk&servicestatustypes=16&hoststatustypes=15&serviceprops=0&hostprops=0

Kashif - we need to open a ticket with argo - shouldnt be using srm-atlas. It might be that this SE is (wrongly) publishing Ops support.

Assume "small hiccups" to begin with!

Brian notes in chat window that "btw , can't access argo links due to nto being in dteam"

Tier 1 update
Brian - Better understanding of the tape system problems, now kinda stable.
FTS upgraded at VO request, that's about it.


Tickets - nothing exciting brought up.

Perfsonar
Brian - PIC are doing sustained 10m IPv6 perfsonar tests - other sites might be interested in that. It is quite an invasive test though.
Pete G- we might be interested - our IPv6 is a lot better then our IPv4 results 
Brian-IPv4 tends to be more congested, so probably not as good a target for tests.
Pete G - that's probably why our Ipv6 is better then IPv4

Reminder - quarterly reports.
Pete G - will look at reviewing the reports today to see if they need updating, hopefully in time for this round of reports but if not then for next time.

AOB
Pete G mentioned the possibility of moving to fortnightly Ops meetings over the Summer - there was overwhelming support for this idea.

Chat Window.

I think it was related to a gridftp se with only 1G nic
