Agenda

• CSCS Status
  • NFS temporal relocation
• Other Sites Status
  • T3_CH_PSI
    • After the maintenance shutdown of Jan 8th there is one older Sun Fire X4100 with a broken service processor and yet another defect Thor Seagate disk (funny enough, the failing disk is one of the unused spare disks)
    • ran stably over the vacation period. In the first working week we had a dcache failure based on the posgresql DB going into a strange state. The effect was that all connections just kept hanging after the initial handshake. Ok after restart of DB.
    • Fabio Martinelli will join the PSI Scientific Computing group on Feb 1st. He will take over the T3 administration as his main responsibility
• (Derek) We need to keep better accounting for reports to funding agencies (e.g. we should add metrics for monitoring the filled SE space per experiment). Also see ResourceAccounting2010
• New Twiki Index (left bar)
• Firewall and Thumper migration delay
• PhaseD upgrade status

Minutes

• The most interesting news is the request from ATLAS to merge MCDISK into DATADISK with immediate effect. The procedure should be as follows: move all free space (with a couple of TBs of margin) from MCDISK to DATADISK. The cloud DDM will then move all files from MCDISK to DATADISK and will eventually advise when it is OK to discontinue the MCDISK token and move all its space to DATADISK. It is foreseen that the whole procedure be complete by beginning of February.
• Coming up very soon: "Networking Requirements for LHC Data Analysis in Germany": http://indico.desy.de/conferenceDisplay.py?confId=3823. 1 person per tier-2 associated with Germany is formally invited
• As far as site news are concerned, here is what is going on at UNIBE-LHEP:
  • 1) migrated to NGI_CH in GOCDB. Waiting to begin the certification process
  • 2) ce.lhep.unibe.ch now tested within the pre-production instance of the German Nagios: https://rocmon-fzk.gridka.de/nagios/cgi-bin/status.cgi?hostgroup=all&style=detail
  • 3) DPM hardware delivered and installation has started. Head node running glite-DPM_mysql and bdii-site, 3xDisk servers running glite-DPM_disk, all on SLC5
