OSG-EDU Site

This is currently just a brain dump. I'll have to re-visit this page and organize it.

Machines

• Gatekeeper - osg-edu
• Worker nodes - osgs-c01 - osgs-c09
• Currently, osgs-c01 and osgs-c04 do not work (one of them does not yet exist, and the other has hardware problems)

The configuration on these machines is controlled by cfengine. Some directories of importance are:

• /usr/local/cfengine/inputs - The configuration of what gets set up
• /var/cfengine/inputs - Roughly the same as the other inputs directory. I don't know the different between them :)
• /usr/local/cfengine/outgoing - Some of the files that are distributed. Other files are copied right from the head node to the worker nodes. Check the configuration files for details

OSG software setup

OSG Software setup:

• The gatekeeper install is at /opt/osg-1.0
• The worker node client is installed at /nfs/wn_client
• The pre-installed Condor is installed at /usr. The logs are at /var/condor/logs. The config is at /etc/condor.
• $OSG_APP is /nfs/osg-app. I have no idea if this is important, but it was a required entry during configure-osg.sh, and I thought it needed to be on the shared file system, so I put it here.

Our site name with the GOC is WISC-OSG-EDU (VORS)

VOs supported & grid-mapfile

Each VO is mapped to a username. Important: These usernames must have their home directories on the shared filesystem (in /nfs)

• OSG-EDU - osgedu
• MIS - mis

If you want to run jobs on this machine for testing, you will need to add yourself to the grid-mapfile. The file to edit is at /opt/osg-0.8/edg/etc/grid-mapfile-local. Add an entry like the following:

"/DC=org/DC=doegrids/OU=People/CN=Scott Kronenfeld 301773" osgedu 

The first part is your certificate info. The second part is the UNIX user to run as. You must either map to the osgedu user or the mis user (you cannot map to your own user because your home directory is not shared on NFS). Then run $VDT_LOCATION/edg/sbin/make-gridmap to force an update to the grid-mapfile.

Every few months, a new VO package will be released. Follow the instructions from the GOC for the update, and afterwards, fix the edg-mkgridmap.conf file. There are two steps:

• Comment out all VO lines except for the VOs we support above
• Add a line to point at the grid-malfile-local. Check the end of edg-mkgridmap.conf.orig for this line. It will look something like "gmf_local /opt/osg-0.8/edg/etc/grid-mapfile-local" (but the exact path may change as we upgrade OSG versions)

OSG-RSV

The RSV user is 'rsv'. I requested a DOEGrids certificate for this user (Scot Kronenfeld (RSV) 211087). I have created a long lasting proxy, but this will need to be periodically regenerated (we don't have a current decision on how often to do this). The password to create the proxy is a standard password we use in the VDT.

Support

Scot is signed up for the OSG-SITES mailing list. Should anyone else be?

The vdt-support email is the contact for our OSG-EDU site.
