LCG Operations Weekly Report
|
|
|
Summary
of status and progress of the LCG Operations. This report covers the WLCG
activities since the last MB meeting. All daily meeting summaries are
available here: https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOperationsMeetings.
Some remarks to the slides linked from this meeting’s agenda are noted
below. Slide 7: In
response to a question from Philippe Charpentier about support at sites
during the week-end, it was clarified that the MOU does not specify this but
rather states averages for uptimes over a year. In order to address possible
differences between expectations and the service levels provided, Ian Bird
proposed to review this during the Collaboration Workshop in Slide 8:
See further information below on the data loss in CASTOR at CERN. Slide 10:
Ian Bird stressed the need to avoid adding non essential functionality
changes. Alberto
Pace presented slides attached to this item on the agenda page. He described actions
taken and planned following the incident of data loss in CASTOR at CERN. Concerning
the possibility of physically setting the write protect switch once data has
been written to the tapes, Ian Fisk added that this is already done at FNAL.
It provides useful protection from software errors as well as manipulation by
a malicious insider. CERN has already contacted FNAL for details on this. It was
agreed that a review of operational procedures should take place for all
incidents involving data loss. |
