Integration Phase 11 (Oct 1 - Dec 31, 2009 - FY10Q1)

• Update LFC to version 1.7.2-4
• Two new methods have been added to the LFC server and the API: lfc_delreplicasbysfn() and lfc_registerfiles(), for the bulk removal or addition of entries.
• http://glite.web.cern.ch/glite/packages/R3.1/x86_64/updates.asp

Procedure

• Stop LFC:

      /etc/init.d/lfcdaemon stop
  

• Back up old installation:

      /bin/mv /opt /opt-backup; mkdir /opt
  

  (note: /opt was used as base directory for this install)

• Update pacman:

      cd /opt
      wget http://atlas.bu.edu/~youssef/pacman/sample_cache/tarballs/pacman-latest.tar.gz
      tar xfz pacman-latest.tar.gz; mv pacman-3.29 pacman
      cd pacman
      . setup.sh
  

• Fetch the current LFC package:

      pacman -get http://vdt.cs.wisc.edu/vdt_200_cache:LFC
  

• Set up the globus/TRUSTED_CA symlink

      cd /opt/globus; ln -s /etc/grid-security/certificates TRUSTED_CA
  

• Set up the LFC config file

      /bin/cp /opt-backup/lcg/etc/NSCONFIG /opt/lcg/etc
  

  (Note - this file contains the MySQL? password)

• Update database schema:

      cd /opt/lcg/share/LFC/lfc-support-1.6.0/
      mysql -u lfc_user -p lfc_password --database cns_db < migrate-mysql-schema-to-3-0-0.sql 

  (Note: a few of the commands in this file caused SQL errors, like Duplicate column name 'ctime'. To work around this run the SQL commands individually.)

• Restart LFC

      /etc/init.d/lfc start
