Adding a new VO
Collect information about the new VO
Go to the CIC portal ([1]) to collect information about the new VO.
Relevant information are the VOMS server(s), the content for the vomses file, possible VOMS roles and groups to be supported, indications of the number of required pool accounts etc.
Create pool accounts and the grid map dir
Find the next free Unix group ID and user ID range for the pool accounts. This can be achieved with via an ldapsearch query, or easier by using the ldap browser (LBE). LBE is available at the Nikhef desktops via /global/ices/toolset/bin/lbe.
Create pool accounts, home directories for the pool accounts and gridmapdir entries using the procedure described at the following page: [[2]].
Create a software installation area
TBD
Add the VO configuration to Quattor profiles
All modifications to the Quattor set up are located in the template hierarchy under the facility-specific directory $L/cfg/facility/facility-name where $L points to the conf directory under the Quattor root directory. Unless specified differently, all files mentioned here are relative to the facility-specific directory.
file: lcg2/yaim/pro_vo_voname.tpl Configuration of VO settings like the VOMS server, contents for the vomses file, location of the software installation directory, the default storage element etc. It is recommended to copy an existing template, rename it and customize its contents.
file: lcg2/yaim/pro_config_lcg2_vos.tpl In this file, include the VO-specific file created above.
file: lcg2/yaim/pro_lcg2_config_yaim_files.tpl Add 1 line per pool account group associated with the VO to the definition of variable USERSCONF. This line should refer to the first pool account in the group only (because we do not use Yaim to create these users). Add all supported VOMS roles and groups to variable GROUPSCONF.
file: lcg2/yaim/pro_queue_access.tpl Add the name of the VO and optional VOMS FQANs to the QUEUE_GROUP_ENABLE variables that correspond to the queues to which the VO users may submit jobs.
file: lcg2/pro_lcg2_service_maui.tpl Add a line to the Maui configuration to specify the fair share and priority of the VO.
file: lcg2/yaim/pro_voms_trustanchors.tpl If the server certificate of the VOMS server is not installed via e.g. an rpm, it should be included in this template.
