AGLT2 5mSpeakers: Robert Ball (University of Michigan (US)), Dr Shawn McKee (University of Michigan ATLAS Group)
Very little out of the ordinary has occurred in the past 2 weeks. We are hoping to have the MSU R630 online yet today, as the MSU switch configuration was finally debugged at the end of last week, and all configurations for the NICs are now in place as of early this morning.
We will take an "at risk" SE downtime on Friday to upgrade the dCache rpm at our site. This will also give us an opportunity to examine an msufs02 NIC that has been bouncing since early in January. As it is part of an active/active bond it is not critical, but it is both limiting and annoying.

NET2 5mSpeaker: Prof. Saul Youssef (Boston University (US))
It has been a busy fortnight at NET2:
o DELL equipment has arrived at MGHPCC except for 1 switch
o Will borrow a switch and install everything next week, operations soon after.
o Augustine went to Ceph school as I expect this to likely be in our future.
o Large transfers of RAW data from NET2 to the other US T2s seems to be done. This is in preparation for re-reprocessing which may (as I understand it) begin as soon as the weekend.
o We have been having occasional problems with FAX where up to ~1000 files are open on the FAX node, linux load ~ 1000 and errors start to appear in the FAX logs.
o There is a problem with availability testing at Harvard that we have to track down.
o We still need to transition to HTCondor.
o Working with MOC team (Massachusetts Open Cloud) to add NET2 worker nodes from a pool of MOC resources.
o Working with BU networking on a WAN upgrade plan.
o Smooth operations otherwise.
