Storage Plugin : Arkivum

In this tutorial we will look at installing the Arkivum Storage Plugin. This plugin allows you to use an alternative storage location and how to mount a Samba (CIFS/Windows) share to store that data.

This plugin was designed to mount the Arkivum Storage system, but could equally be used to store data on any CIFS/Samba system

Before You Start

​Install smbfs on the eprints server

apt-get install smbfs;# Debian
yum install cifs-utils;# Redhat

Note: Redhat uses cifs mounting rather than samba (so replace smbfs for cifs if using redhat

Make sure you have:

• Access to: /etc/fstab
• The UID of eprints and GID of the webserver group (likely to be www-data or apache)
• A directory and read/write access for the above user somewhere on the system

Preparing the directory

ON THE Arkivum Unit, or Samba Server

• Create the directory you want to mount the Astor Archive on to (eg /mnt/Archive)
• mkdir your_di​rectory
• edit /etc/fstab and add to the bottom:

//ASTOR_SERVER/astor /YOURDIR_ON_EPRINTS cifs defaults,guest,file_mode=0666,dir_mode=0777,uid=USERS_UID,gid=USERS_GID,forcegid,forceuid,rw 0 1

should you want to connect as ​​a specific domain user, use:​

//ASTOR_SERVER/astor /YOURDIR_ON_EPRINTS        cifs    defaults,sec=none,rw,soft,username=DOMAIN_USERNAME,password=DOMAIN_PASSWORD,dom=DOMAIN,uid=EPRINTS_UID,gid=APACHE_GID,forcegid,forceuid 0 0

• at the command line run: mount /YOURDIR_ON_EPRINTS
• running: df -h ; #will test to see if the mount succeeded

Configure Apache

On the Eprints Server

Remember to add the directory set as archive in the apache config file.

It should look like this:

<Directory "YOURDIR_ON_EPRINTS">
  Options FollowSymLinks
                  AllowOverride none
                Order allow,deny
                Allow from all
</Directory>​
  <Location "YOURDIR_ON_EPRINTS">
    PerlSetVar EPrints_ArchiveID fluffy

    Options +ExecCGI
    Order allow,deny
    Allow from all
  </Location>

The Storage Plugin

You can download the storage plugin from here: [1]

Then edit the main file to decide your rules for using the storage plugin:

eprints3/lib/storage/default.xml

<store xmlns="http://eprints.org/ep3/storage" xmlns:epc="http://eprints.org/ep3/control">
        <epc:choose>
                <epc:when test="datasetid = 'document'">
                        <plugin name="ArkivumR"/>
                </epc:when>
                <epc:otherwise>
                        <plugin name="Local"/>
                </epc:otherwise>
            
        </epc:choose>
</store>

This example would use the Arkivum Plugin for documents, and the normal plugin for everything else.

Check in E-Prints

""If the installation is successful, you should see the Akivum storage available by going here:"" E-prints web page --> LOGIN --> ADMIN --> CONFIG TOOLS --> STORAGE MANAGER (NB: if the file permissions are wrong, the storage wont show)
