Week of 080121

Open Actions from last week: Announce the supported middleware versions for the Feb run at the Monday weekly operations meeting.

Monday:

see the weekly phone conference in Indico

Tuesday:

Experiment report(s):

ALICE: (PM) One SL4 VO-vox is already in production at CERN and sites at RAL, in Mexico and in Russia are currently migrating. All ALICE Tier1 should have SL4 VO-boxes by the February startup.

LHCb: (HR) There is a meeting happening now discussing configuring their Castor Tier1 sites for CCRC'08.

CMS: (DB) [ apologies: limited attendance to these meetings this whole week due to participation to CMS DM/WM workshop in Lyon]. --- Discussion on megatable figures from which to extract CCRC transfer goals almost finalized. --- Polling T2s (supporting the CMS VO) on SRMv2 deployment plans: in progress. We are counting which T2s we can have with SRMv2, and plan transfer tests accordingly.

Core services (CERN) report: A fix to the current gfal problem is being targeted for next Monday.

DB services (CERN) report:

  • The patch for the streams bug which has affected the ATLAS streams set-up since last Tuesday has been delivered by Oracle this morning and has been applied to the source database of the ATLAS online RAC (ATONR). It is a non-rolling patch and therefore a service interruption of one hour was necessary for ATONR. The streams capture process has been restarted. (The bug was observed after a procedure to compact and compress the PVSS archived data, developed in collaboration with ATLAS and IT-CO).

Monitoring / dashboard report:

Release update:

Questions from sites/experiments:

Question by CMS: should we expect a regular review by WLCG on SRMv2 deployment status at Tier-2s in the next days, approaching the deadline?

BNL: (ME) A concern is access to ATLAS conditions data by Tier1 reprocessing jobs. Various placement models are being looked at. JDS asked if their space requirements are clear to which the reply was Yes but configuration is not complete.

AOB: (JDS) We are going to document known issues and any workarounds. We will also be discussing high level monitoring of ccrc'08. I am thinking of a weekly report based on the 3 types of metrics - experiment scaling factors, experiment defined critical services and MoU targets.
