*[[Installing_dcache_pool]] gives a description on how to add a pool v180

==== Headnode settings ====
*On the headnode in PoolManager.conf add these lines
<pre>
psu create pool pool2-shadow
psu create unit -net 192.168.99.0/255.255.255.0
psu addto ugroup all_net 192.168.99.0/255.255.255.0

==== Pool node settings ====

*behar030 has been used as the reference storage box
*Install dcache software
<pre>
wget http://www.dcache.org/downloads/1.9/dcache-server-1.9.5-29.noarch.rpm
rpm -ivh dcache-server-1.9.5-29.noarch.rpm
wget http://www.dcache.org/downloads/1.9/dcache-srmclient-1.9.5-23.noarch.rpm
rpm -ivh dcache-srmclient-1.9.5-23.noarch.rpm
</pre>

*In the v180 setup the dCacheSetup file differs from the template file with several aspects
**ourHomeDir and ourHome are set
**serviceLocatorHost is defined to ''hostname''
**java version is not set to a specific version
**java_options are different
**metaDataRepository, metaDataRepositoryImport, parallelStreams, srmBufferSize, srmTcpBufferSize, billingToDb parameters are set explicitely
**logArea=/var/log/dcache is set to specific subdirectory
*The v180 file has been put in place with the necessary changes
*The v195 log4j.properties is kept
*PoolManager.conf: seems to be the default file in v180 and the v195 and v180 don't seem to differ
*dcache.kpwd: put file of behar030 in place
*dcachesrm-gplazma.policy: put behar030 file in place
*logConfig.xml: kept v195 file
*node_config: set behar030 version of file but change the
*srm_setup.env keep 195 file
*/opt/pnfs/etc/pnfs_config: no such file
*/usr/etc/pnfsSetup: no such file

*generate keys
<pre>
cd /opt/d-cache/config/
ssh-keygen -t rsa1 -b 768 -f ./server_key -N ""
ssh-keygen -t rsa1 -b 1024 -f ./host_key -N ""
</pre>

*run install script
<pre>
/opt/d-cache/install/install.sh
</pre>

*make log directory
<pre>
mdkir /var/log/dcache
</pre>

*look into http://mon.iihe.ac.be/trac/t2b/wiki/Installing_dcache_pool for the procedure to add a pool to the headnode
*In short it goes like this
**there is a poollist file on the pool node /opt/d-cache/config/pool2-shadow.poollist. It contains this line
<pre>
pool2-shadow /storage/1/pool sticky=allowed recover-space recover-control recover-anyway lfs=precious tag.hostname=pool2-shadow
</pre>
**must make sure this /storage/1/pool/data directory exists, in this case made a symlink to a larger partition
<pre>
ln -s /var/storage /storage
mkdir /var/storage
</pre>
**then create the pool
<pre>
/opt/d-cache/bin/dcache pool create 20g /storage/2/pool/
</pre>
**Don't forget to add the pool in PoolManager.conf on the headnode and restart dcache on both headnode and poolnode
*some more directories are created when the dcache is started
*scp ccq:/root/dCache_essential_config/behar030_essential_config/setup /storage/1/pool/setup.orig.behar

*Add lcg-CA rpms
<pre>
wget http://repository.egi.eu/sw/production/cas/1/current/repo-files/EGI-trustanchors.repo
mv EGI-trustanchors.repo /etc/yum.repos.d/
yum install ca-policy-egi-core
yum install lcg-CA
</pre>

*start dcache
<pre>
/opt/d-cache/bin/dcache start
</pre>
