---+ Storage Upgrade
---++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 [[http://www.dcache.org/manuals/Book/cookbook/cb-pool-vacate.shtml][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
<pre>
/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
</pre>
now inject it in your fresh install  DEST admin node (we assume that all configuration files are set up)
<pre>
dropdb -U pnfsserver admin
dropdb -U pnfsserver data1
createdb -U postgres admin
createdb -U postgres data1
psql -U postgres admin<admin.dump
psql -U postgres data1<data1.dump
</pre>
and restart your pnfs system.

  * May be consider change to a Chimera , following these instructions

---++ Guidelines
Postgres
<pre>
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
</pre>

Java
<pre>
chmod +x jdk-6u12-linux-x64-rpm.bin 
./jdk-6u12-linux-x64-rpm.bin 
java -version
</pre>

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= .
