• • Import pnfs database:
  • go to jefke.wn and in /storage/userbackup/Maite_Db_backup/ find a file with pnfsdb.tar (any will do).
  • Untar it in the correct location. Hint: tar -tf to see where the tree structure of the tarball.
  • This configures contains the metadata for the pnfs database
  • Also copy the last file full_*.gz, which contains the full pnfs database.

su - postgres
zcat <path to gzipped full database> | psql postgres

• install dcache and check md5sum on site

wget http://www.dcache.org/downloads/1.9/dcache-server-1.9.12-8.noarch.rpm
md5sum dcache-server-1.9.12-8.noarch.rpm
must be 3b3f358e57ccd574df19131868c9f9e4
rpm -ivh dcache-server-1.9.12-8.noarch.rpm

/etc/init.d/postgresql restart

• This section is optional, it initialises chimera which we don't use at the moment. SKIP this section

createdb -U postgres chimera
createuser -U postgres --no-superuser --no-createrole --createdb --pwprompt chimera
psql -U chimera chimera -f /opt/d-cache/libexec/chimera/sql/create.sql
createlang -U postgres plpgsql chimera
psql -U chimera chimera -f /opt/d-cache/libexec/chimera/sql/pgsql-procedures.sql

• Create db and user

createuser -U postgres --no-superuser --no-createrole --createdb --pwprompt srmdcache
createdb -U srmdcache dcache

• Generate keys

##ssh-keygen -b 768 -t rsa1 -f /opt/d-cache/config/server_key -N ""
##ssh-keygen -b 1024 -t rsa1 -f /opt/d-cache/config/host_key -N ""
ssh-keygen -b 768 -t rsa1 -f /opt/d-cache//etc/server_key -N ""
ssh-keygen -b 1024 -t rsa1 -f /opt/d-cache//etc/host_key -N "" 

• edit /opt/d-cache/etc/dcache.conf and add:

dcache.layout=head
webadminAuthenticated=true

• execute following commands, this will start dcache:

/opt/d-cache/bin/dcache import cacerts
/opt/d-cache/bin/dcache start

• edit /opt/d-cache/etc/layouts/head.conf to enable the correct services; Also edit /opt/d-cache/share/defaults/dcache.properties if you want to use pnfs
  
  

dcache.namespace=pnfs

• install a more recent version of dcap:

cd /etc/yum.repos.d/
wget http://grid-deployment.web.cern.ch/grid-deployment/glite/repos/3.2/glite-UI.repo
yum install dcap

• This installs the following RPMs

dcap-2.47.5-0.x86_64.rpm
libdcap-2.47.5-0.x86_64.rpm

• run pnfs and the pnfs startups script. This script needs to be ran only once.

/opt/d-cache/libexec/preparePnfs.sh
/etc/init.d/pnfs start

• To /opt/d-cache/config/PoolManager.conf you have to add InstallDcache_PoolManagerConf

adminDoorDomain
spacemanagerDomain
namespaceDomain

statisticsDomain
httpdDomain
gPlazmaDomain
utilityDomain

• • The complement of these are
  • nfsDomain vs. pnfsDomain: name change? oth, nfsDomain is not mentioned in the manual
  • adminDomain vs. adminDoorDomain: name change?
  • gPlazma-maiteDomain vs gPlazmaDomain: name change?
  • infoProviderDomain vs. infoDomain: name change?
