3 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Outline Disk Pool Manager Overview How to install a DPM Server DPM testing

4 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Disk Pool Manager Overview The Disk Pool Manager (DPM) is a lightweight solution for disk storage management, which offers the SRM interfaces. The DPM head node has to have one filesystem in this pool, and then an arbitrary number of disk servers can be added by YAIM. The DPM disk servers can have multiple filesystems in the pool. The DPM head node also hosts the DPM and DPNS databases, as well as the SRM web service interfaces.

5 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Installing DPM

6 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Installation Pre-requisites Start from the base machine you installed in the INTRODUCTORY tutorial Verify that these packages are installed and properly configured: –Java SDK –ntp daemon –glite-yaim-core Also check that your host certificates are present in /etc/grid- security and have proper permissions: -rw-r--r-- 1 root root1127Jun 14 12:27 hostcert.pem -r root root887 Jun 14 12:28 hostkey.pem

7 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America my-site-info.def customization Copy /opt/glite/yaim/examples/site-info.def into /root/siteinfo/site-info.def and edit these fields: MY_DOMAIN= ring.pucp.edu.pe ring.pucp.edu.pe MON_HOST=rgmasrv.ct.infn.it JAVA_LOCATION="/usr/java/j2sdk1.4.2_13“ DPM_HOST=limaXX.$MY_DOMAIN DPMPOOL=Permanent DPM_FILESYSTEMS="$DPM_HOST:/storage" DPM_DB_USER=dpmdbuser DPM_DB_PASSWORD=dpmdbpassword DPM_DB_HOST=$DPM_HOST

8 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Other requisites We need to create one or more partitions for DPM In this example installation we will create the /storage directory, specified into the DPM_FILESYSTEM configuration variable: – mkdir /storage Add this row (if not exist) to /opt/glite/yaim/etc/users.conf: – 151:dpmmgr:151:dpmmgr:x:dpm:

9 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Middleware installation with YAIM We are ready to install the DPM Server: /opt/glite/yaim/bin/yaim -i -s /root/siteinfo/site-info.def - m glite-SE_dpm_mysql This command will download and install all the needed packages for the DPM Head Node and the Disk Server.Now we can configure the node: /opt/glite/yaim/bin/yaim -c -s /root/siteinfo/site-info.def - n SE_dpm_mysql

10 12th EELA TUTORIAL - USERS AND SYSTEM ADMINISTRATORS – Lima, September, 2007 E-infrastructure shared between Europe and Latin America Firewall configuration The following ports have to be open: –DPM server: port 5015/tcp must be open locally at your site at least (can be incoming access as well), –DPNS server: port 5010/tcp must be open locally at your site at least (can be incoming access as well), –SRM servers: ports 8443/tcp (SRMv1) and 8444/tcp (SRMv2) must be opened to the outside world (incoming access), –RFIO server: port 5001/tcp must be open to the outside world (incoming access), in the case your site wants to allow direct RFIO access from outside, –Gridftp server: control port 2811/tcp and data ports /tcp (or any range specified by GLOBUS_TCP_PORT_RANGE) must be opened to the outside world (incoming access).
