Feedback from site admins after
Testbed1 experience

TB1 integration from site admins
• We (spanish Testbed sites) are one of the
EU-DataGrid “remote” (as described in
D6.1) Testbed sites
– Not yet in the Testbed1
• Here, I will briefly report on our activities
on the Testbed1up to now and try to
extract some “Testbed site needs” from
this experience

EDG TB1 s/w installation status
• Our 1st target:
– Install the 2 basic Grid Elements on each site
CE Gatekeeper +
WN
GDMP server(s) Alice,Atlas,CMS,LHCb
Biomed
SE Eathobs
Wpsix, iteam
EDG TB1 configuration @IFAE
GDMP servers
Atlas
Gatekeeper
+ WN
grid-w1.ifae.es grid-s1.ifae.es
• GDMP-Atlas VO (for the moment)
• Gatekeeper • Gatekeeper (fork)
• PBS • NFS server, exporting:
• GIIS /home/atlas001,…
– ifae (local site GIIS) /etc/grid-security/certificates
– es (country GIIS) (also grid-mapfile and gridmapdir)
• edg-crl-update
• edg-mkgridmap
• edg-pinger
Testbed1 activity
Try to “stay tuned” within the information flow:
– Documentation

• Key document – EDG Installation Guide
• Other documents in the WP6 Web page
– Bugzilla
• Keep an eye on it to be aware of bug status
• Use it to report about malfunction discovery

General comment:
Up to now it has been quite hard for a “remote site” to
follow the Testbed1 evolution from those sources
“We are shooting on a moving target” (F. Gagliardi)
TB info sources: EDG Install Guide
The EDG Installation Guide
• Main source of information
• It is an “evolving document” (current from 3/02/2002)
– It is “condemned” to be incomplete
http://www.pi.infn.it/~flavia/se_config.html
http://www.lnl.infn.it/datagrid/wp4-install/testbed-report_2/index.html
• Sometimes the info is a bit confusing or
inconsistent w.r.t. other WP’s docs
– E.g. Configuration of the CE & SE Info Systems…
TB info sources: EDG Install Guide
E.g. Configuration of the CE&SE Info Systems:
• Examples of info-mds.conf are given twice
– 7.5(7.6) CE(SE) Configuration, Configuring GRAM and GRIS
– 8.1 Ftree&MDS Info Services and Info Providers
• For the parameters inside globus.conf:
– From WP3 Web (http://hepwww.rl.ac.uk/DataGridMonitoring)
GRID_INFO_GRIS_REG_GIIS=ral - The site name
GRID_INFO_GRIS_REG_HOST=hostname.rl.ac.uk
– From WP3 Document “MDS Deployment Testbed-1”
GRID_INFO_GIIS_1=tb1-pbs
GRID_INFO_REG_GIIS_1=ral
GRID_INFO_REG_HOST_1=hostname.rl.ac.uk
– From EDG Installation Guide
GRID_INFO_GIIS_1=ce - The GIIS name
GRID_INFO_REG_GIIS=ral - The site name
GRID_INFO__REG_HOST=hostname.rl.ac.uk
TB info sources: Bugzilla & mailing list
Bugzilla (http://marianne.in2p3.fr/datagrid/bugzilla)
• Keeps record of s/w features/bugs
• Information about which are the open/closed
problems at a given moment
• Searchable: Clear classification in terms of
programs (GDMP, LCFG…) and versions
• New category “Testbed configuration” added on
mid December:
– This might be the best info repository for site admin
issues
– Still, some information here is not totally up to date…
TB info sources: Bugzilla & mailing list
The ITeam mailing list
www.listbox.cern.ch/earchive/hep-proj-grid-integration-team/
• This is the ultimate source of truly real-time
information concerning TB1 installation issues
– E.g. Replica Catalog installation instructions,
SE/GDMP configuration issues…
• The throughput is high enough (~102 mails/day)
to make online reading/filtering a tough task
• Searchable: But not as good as bugzilla to
search for “all those problems related to a given
service”
