Guidelines for pnfsManager

Postgres

cd /tmp/
wget http://yum.pgsqlrpms.org/reporpms/8.3/pgdg-centos-8.3-4.noarch.rpm
rpm -ivh pgdg-centos-8.3-4.noarch.rpm
yum install postgresql postgresql-server
chkconfig postgresql on
service postgresql initdb
chkconfig postgresql on && service postgresql start
/usr/bin/postgres --version

Java

chmod +x jdk-6u12-linux-x64-rpm.bin 
./jdk-6u12-linux-x64-rpm.bin 
java -version

PNFS

It is know a dependency with an libpq.so.4 for 32 bits. The first workaround is include a symbolic link of /usr/lib64/libpq.so.4 to /usr/lib/libpq.so.4 . The second one is install pnfs-postgresql using rpm -ivh --nodeps .

Guidelines for SMRManager

Install Java in this node;
we need a host certificate installed (copied from osg-se.sprace.org.br ) at /etc/grid-security and also a symbolic link to certificates directory. Use automount to mount our computer element directories:

 echo "/osgce     /etc/auto.spraid01   --timeout=30" >> /etc/auto.master
 echo "OSG     -rw,soft,bg,rsize=8192,wsize=8192,tcp   192.168.1.150:/OSG" > /etc/auto.osgce
 chkconfig autofs on
 ln -s /osgce/OSG /OSG
 ln -s /osgce/globus/TRUSTED_CA  /etc/grid-security/certificates

Install PhEDEx

Pools

To change our pools to a 64 bits node host, important directories:

The pool directory. It contains a control/ directory with meta data, a data/ directory with data, a one or more setup files.
An entry in the pool_name_n.poollist (i.e. spraid02.poollist) file stored in the config/ directory of the dCache installation. This entry contains the path to the pool directory, the name of the pool and various settings.

Follow these steps to move a pool. Let's assume you move pool POOL_1 from SOURCE to DEST. SOURCE and DEST may

Make sure the pool is shut down /opt/d-cache/bin/dcache stop.
Copy the directory containing POOL_1 from SOURCE to DEST (take care not to overwrite files at DEST).
Copy the SOURCE.poollist file from SOURCE to DEST (you can add more pools in this same file)
Restart the pools at DEST

Important: Do not start the pool at SOURCE after you moved the files.

Another possibility is using dcache CopyManager to just copy POOL_1 from SOURCE to DEST.

Admin

It means that we want to migrate our PNFs to a different host, so we need to export our database. In our SOURCE admin it is done like a

/opt/d-cache/bin/dcache stop
/opt/pnfs/bin/pnfs stop
pg_dump -U pnfsserver admin >admin.dump 
pg_dump -U pnfsserver data1 >data1.dump

now inject it in your fresh install DEST admin node (we assume that all configuration files are set up)

dropdb -U pnfsserver admin
dropdb -U pnfsserver data1
createdb -U postgres admin
createdb -U postgres data1
psql -U postgres admin
and restart your pnfs system.
