  1. Testbed Site • EDG 1.2 • LCFG • GridPP Replica Catalogue • GDMP and multiple VO’s Owen Maroney University of Bristol 1

  2. SE, CE, 2 WN’s running PBS queue • Standard EDG1.2 • Run from LCFG server • In process of adding in working farm • 15 worker nodes • not using LCFG! • Also local UI • Replica Catalogue for GridPP VO • Being updated to EDG1.2 Owen Maroney University of Bristol 2

  3. LCFG • Used to set up 1.1.2 EDG version • Painful process! • For 1.2 used the GridPP network installation • Not a painful process! • gpp-install.sh can also be used to upgrade EDG version • Webpages on GridPP Site are excellent! • But could this be a problem? Site support? • Need the site test suite? Owen Maroney University of Bristol 3

  4. LCFG “Disaster Recovery” • CE developed hardware failure • just before Sheffield Demo • As this hosts security, shut-down entire site! • Solution • edit 1 file on LCFG server (switch hardware addresses in dhcp.conf) • Reboot one of the WN from disc • Becomes new CE with exact configuration of old CE • Start PBS server on new CE • Done! Owen Maroney University of Bristol 4

  5. GridPP Replica Catalogue • LDAP server – rc-gridpp.ac.uk • Mapping LFN to PFN • Straightforward but undocumented • In future will need many RC’s? • Currently write permission must be added ‘by hand’ • Need to configure GDMP • multiple VO’s • But: each user is assigned to only 1 VO Owen Maroney University of Bristol 5

  6. GridPP RC Configuration • LCFG configuration: • add to each node profile • #include “gridpp/gridpp-XX-cfg.h” • Modify site-cfg.h file • Add lines • #define SE_VO_GRIDPP • #define SE_GDMP_REP_CAT_GRIDPP_PWD !password! • Add ‘gridpp:/<flatfiles>/gridpp’ to the line • #define SE_VO_ alice:/<flatfiles>/alice …. Owen Maroney University of Bristol 6

  7. GridPP RC Configuration • Post LCFG configuration on CE • Create lock files • touch /<etc>/grid-security/gridmapdir/gridppXXX • In /opt/edg/etc/mkgridmap.conf • group ldap://vo.gridpp.ac.uk/ou=testbed,dc=gridpp,dc=ac,dc=uk .gridpp • auth ldap://grid-vo.nikhef.nl/ou=People,o=gdmpservers,dc=eu-datagrid,dc=org • group ldap://grid-vo.nikhef.nl/ou=apptb,o=gdmpservers,dc=eu-datagrid,dc=org gdmp Owen Maroney University of Bristol 7

  8. GridPP RC Configuration • On CE, WN • Add file gdmp-rc-values.sh to /etc/profile.d • Copy file rc-gridpp.conf to /opt/edg/etc/gridpp • On UI, also need rc-gridpp.conf • User must declare environment variables • export RC_CONFIG_FILE=/opt/edg/etc/gridpp/rc-gridpp.conf • export GDMP_CONFIG_FILE=/opt/edg/etc/gridpp/gdmp.conf • The SE must be included in the gdmpservers VO • Notify Grid.Support@nikhef.nl • Attach the SE host certificate file Owen Maroney University of Bristol 8

  9. Multiple VO membership • Currently: each user is mapped to one (and only one) VO. • Can only use the RC of that VO • To force an override, write the user into grid-mapfile-local for different VO eg: • “/O=Grid/OU=UKHEP/CN=First Last” .gridpp • But no longer in original VO! • Goes against security considerations Owen Maroney University of Bristol 9
