Maintaining Elasticsearch

Since version 0.9, Archivematica uses Elasticsearch as its search engine. Elasticsearch stores information about AIPs and Transfers in backlog. This data can be searched from the Archival Storage and the Backlog tabs on the Archivematica dashboard.

Note

As of Archivematica 1.7, this feature can be fully or partially disabled.

Rebuild the indexes

Archivematica includes two Django commands to regenerate the Elasticsearch indexes. These commands require access in the local filesystem to the location paths of the AIP and Transfer Backlog storage locations. These usually are located in the following paths:

  • /var/archivematica/sharedDirectory/www/AIPsStore
  • /var/archivematica/sharedDirectory/www/AIPsStore/transferBacklog

You should confirm the paths of your installation in the Locations tab of the Storage Service.

AIP indexes

To recreate the AIP indexes from files run the following command, passing the path of the AIP storage location you confirmed above.

Note

Please note, the execution of this command may take a long time for big AIP storage locations, especially if the AIPs are stored compressed.

sudo -u archivematica bash -c " \
    set -a -e -x
    source /etc/default/archivematica-dashboard || \
        source /etc/sysconfig/archivematica-dashboard \
            || (echo 'Environment file not found'; exit 1)
    cd /usr/share/archivematica/dashboard
    /usr/share/archivematica/virtualenvs/archivematica-dashboard/bin/python \
        manage.py rebuild_elasticsearch_aip_index_from_files \
            /var/archivematica/sharedDirectory/www/AIPsStoree --delete-all
";

The command accepts the following parameters:

  • [storage_location_path] [REQUIRED]: Path where the AIP storage location is located in the local filesystem.
  • –delete-all: Removes the entire indexes to regenerate the mapping and settings.
  • –delete: Removes matching AIP documents to avoid duplicates but keeps the index mappings and settings.
  • –uuid [aip_uuid]: Index a single AIP from the storage location.

It can be executed multiple times with different paths to index multiple AIP storage locations.

Transfer indexes

To regenerate the Transfers indexes, apart from access to the storage location, the command checks the transfer and transfer files existence in the Dashboard database. The indexes will be fully recreated with the current settings and mappings and populated with the Transfers from the location. Execution example:

Note

Please note, the execution of this command may take a long time for big Transfer Backlog storage locations.

sudo -u archivematica bash -c " \
    set -a -e -x
    source /etc/default/archivematica-dashboard || \
        source /etc/sysconfig/archivematica-dashboard \
            || (echo 'Environment file not found'; exit 1)
    cd /usr/share/archivematica/dashboard
    /usr/share/archivematica/virtualenvs/archivematica-dashboard/bin/python \
        manage.py rebuild_transfer_backlog
";

The command accepts the following parameters:

  • –transfer-backlog-dir [storage_location_path]: Path where the Transfer Backlog storage location is located in the local filesystem. Default: /var/archivematica/sharedDirectory/www/AIPsStore/transferBacklog.
  • –no-prompt: Do not ask for confirmation.

External access

For further interactions with the Elasticsearch indexes, to browse the data or to create visualizations, the following tools are recommended:

The index names are: aips, aipfiles, transfers and transferfiles.

Sauvegarde de données

Dans Archivematica, on recommande de sauvegarder les trois types de données suivantes :

  • Filesystem (en particulier les répertoires de stockage)
  • MySQL
  • Elasticsearch

MySQL sert à entreposer à court terme les données de traitement. On peut sauvegarder la base de données MySQL en utilisant le code de commande suivant :

mysqldump -u <your username> -p<your password> -c MCP > <filename of backup>

Elasticsearch is used to store long-term data. Instructions and scripts for backing up and restoring Elasticsearch are available in the Elasticsearch documentation.

Resolve hanging decisions

« My Transfer or Ingest tab has a red circle indicating that a decision is awaiting user input, but there are no decisions to be made on the screen. How do I get rid of the red circle? »
A red bubble on the Transfer tab at the top of the Archivematica dashboard indicates that a decision is awaiting user input.

Any time a decision in the Transfer or Ingest tab is awaiting user input, Archivematica visually indicates the need for user input by placing a red circle on the tab. The numeral inside the circle indicates how many decisions are awaiting user input on the tab.

It is possible to remove transfers or SIPs from the Transfer or Ingest tab without resolving a decision, which results in the red circle remaining even if there is no decision awaiting user input on the tab. While this isn’t a critical issue, it is annoying. To get rid of the red circle, you need to use a command line tool to resolve the user input first and then either complete or reject the transfer/SIP. In the Archivematica source code, there is a python module containing an RPC client that can give you information about the transfers and SIPs that you have in your dashboard. It also allows you to add user inputs, as an alternative to using the dashboard.

Important

The tool that is currently being used for this workflow, mcp-rpc-cli, may be deprecated or replaced in future releases. These instructions are accurate as of Archivematica 1.7.2.

Note

These instructions work on Archivematica 1.7.x, deployed on either CentOS or Ubuntu via ansible or RPMs. If you are using this tool on a vagrant deployment, please note the specific instructions related to vagrant. For more information about installation methods, please see Installer Archivematica.

  1. Clone the archivematica-devtools repository into your Archivematica source repository and follow the installation instructions found within the repository. On Ubuntu or CentOS, clone the repository to /opt/archivematica. On vagrant, clone the repository to /vagrant/src/. You should be able to access the devtools by running the am command.

  2. Navigate to the Archivematica MCP Client directory and start the mcp-rpc-cli.

    Ubuntu or CentOS:

    sudo -u archivematica bash -c " \
       set -a -e -x
         source /etc/default/archivematica-mcp-client || \
             source /etc/sysconfig/archivematica-mcp-client \
                 || (echo 'Environment file not found'; exit 1)
         cd /opt/archivematica/archivematica-devtools/bin/
         ./am mcp-rpc-cli
     ";
    

    Vagrant:

    sudo -u archivematica bash -c " \
       set -a -e -x
         source /etc/default/archivematica-mcp-client || \
             source /etc/sysconfig/archivematica-mcp-client \
                 || (echo 'Environment file not found'; exit 1)
         cd /vagrant/src/archivematica-devtools/bin/
         ./am mcp-rpc-cli
     ";
    
  3. You should see an output that looks like the snippet here:

    q to quit
    u to update List
    number to approve Job
    Please enter a value:
    

    The above is showing two SIPs that were cleared from the Ingest tab while waiting for user input at the Store AIP decision point. Each SIP is given an entry number, beginning with 0. Note that transfers that were cleared from the Transfer tab while waiting for user input would also appear in this list.

    Below the entry number, we get some basic information about the SIP within the <unit> element (the type, UUID, and the current location). Following that, we have the <choices> element, which presents the currently-available choices for the SIP. The Store AIP decision point gives the user two choices: Reject AIP or Store AIP.

  4. Select the transfer or SIP that you would like to work with by entering the entry number.

    Please enter a value: 0
    

    You should now see a list of the available choices for the transfer or SIP. Each choice is preceded by an entry number.

    Please enter a value:
    
  5. Make the decision by entering the choice’s entry number.

    Please enter a value: 1
    

    In this example, we have chosen to store the AIP by selecting the Store AIP choice. We could now confirm that this action worked by checking the Archivematica instance’s Storage tab to confirm that the AIP was stored.

  6. To update the list and continue, enter u when prompted to enter a value. Repeat the steps above until there are no more choices left to make.

Transfer won’t start

« I try to create a new transfer, but nothing happens. What can I do? »

Sometimes a user may attempt to start a transfer and it will never seem to initiate the Archivematica processes. There are a few issues to look out for and investigate if this happens.

  1. File permissions
First, the issue may be related to file permissions in the transfer source directory. Check the permissions in the directory and on the files to ensure that all files can be read by Archivematica.
  1. System timeouts

If it is a large transfer, it may just be taking a long time to copy the files and initially load them into the system, and the user can wait a bit longer and see if the processes begin after a bit of time. It is also possible that it is taking a long time because some of the system timeouts are being exceeded and the transfer has failed. This can be verified by checking the Storage Service logs and by checking where the transfer exists on the filesystem.

For inadequate timeouts, check the Storage Service configuration and adjust if necessary.

  1. Communication between Dashboard and Gearman

If the transfer has successfully moved to the shared Directory (i.e. it can be found in sharedDirectory/watchedDirectories/activeTransfer/ folders), but is still not showing up in the dashboard, there could have been a problem with the communication between the dashboard and Gearman. Restarting all of the services can resolve this problem and the transfer will appear.

Restart services in the follow order: gearmand, archivematica-mcp-server, archivematica-mcp-client, and archivematica-dashboard.

Note that on some installations, gearmand may be called gearman-job-server.
