Setup

Hyrax migrator configurations

config/initializers/hyrax_migrator.rb

config.skip_field_mode = true
config.migration_user = '[email protected]'
config.upload_storage_service = :file_system
config.ingest_storage_service = :file_system

Tasks on a fresh OD2 Install

Default admin set and collection

bundle exec rails hyrax:default_admin_set:create
bundle exec rails hyrax:default_collection_types:create

Default OD2 admin sets and collections

bundle exec rake oregon_digital:create_admin_sets
bundle exec rake oregon_digital:create_collections

Load workflows

bundle exec rails hyrax:workflow:load

Ingest a single zip bag

  1. scp bagsclean.tar.gz from OD1 server to a local folder /data/tmp/ and untar, which would create bagsclean with subfolders for each seed data collections.

  2. Make a zip version of a single bag /data/tmp/bagsclean/Baseball_jpegs/3t945r08v/ from within the folder, and move it to /data/tmp/batch_baseball/3t945r08v.zip.

  3. Load the console in the server container and run the following to migrate bag located at /data/tmp/batch_baseball/3t945r08v.zip:

$ bundle exec rails c
> Hyrax::Migrator.config.skip_field_mode = true
> Hyrax::Migrator.config.upload_storage_service = :file_system
> Hyrax::Migrator.config.ingest_storage_service = :file_system
> pid = "3t945r08v"
> file_path = "/data/tmp/batch_baseball/3t945r08v.zip"
> w = Hyrax::Migrator::Work.find_by_pid(pid)
> w = Hyrax::Migrator::Work.create(pid: pid, file_path: file_path) if w.blank?
> m = Hyrax::Migrator::Middleware.default
> m.start(w)

To allow a restart, existing records would need to be removed for now (restart for existing records hasn't been implemented yet):

$ bundle exec rails c
> pid = "3t945r08v"
> gid = ActiveFedora::Base.find(pid).to_global_id.to_s if ActiveFedora::Base.exists?(pid)
> Sipity::Entity.find_by(proxy_for_global_id: gid).delete if Sipity::Entity.find_by(proxy_for_global_id: gid).present?
> ActiveFedora::Base.find(pid).delete if ActiveFedora::Base.exists?(pid)
> ActiveFedora::Base.eradicate(pid)
> Hyrax::Migrator::Work.find_by_pid(pid).delete if Hyrax::Migrator::Work.find_by_pid(pid).present?

Ingest a collection or group of zip bags in a folder

  1. scp bagsclean.tar.gz from OD1 server to a local folder like /data/tmp/ and untar, which would create bagsclean with subfolders for each seed data collections.

  2. cd into Baseball_jpegs folder /data/tmp/bagsclean/Baseball_jpegs/ and execute zip_bags.sh.

/data/tmp/bagsclean/Baseball_jpegs/zip_bags.sh

#!/bin/bash

# Usage: cd into the collection folder 'Baseball_jpegs' and run bash zip_bags.sh

# Baseball jpegs (20) collection

# get number of elements in the array
ELEMENTS=${#ARRAY[@]}

# zip from within the directory of each PID
for (( i=0;i<$ELEMENTS;i++)); do
    echo ${ARRAY[${i}]}
    cd ${ARRAY[${i}]}
    zip -r ../${ARRAY[${i}]}.zip .
    cd ..
done
  1. Make batch folder batch_baseball and get the zip files generated with zip_bags.sh 
mkdir /data/tmp/batch_baseball
rsync -r -v /data/tmp/bagsclean/Baseball_jpegs/*.zip /data/tmp/batch_baseball/
  1. Get into the workers container and run BagIngestService for batch batch_baseball 
$ bundle exec rails c
> c = Hyrax::Migrator::Configuration.new
> c.upload_storage_service = :file_system
> c.ingest_storage_service = :file_system
> c.file_system_path = "/data/tmp"
> c.ingest_local_path = "/data/tmp" 
> i = Hyrax::Migrator::Services::BagIngestService.new(['batch_baseball'], c)
> i.ingest
  1. Inspect the logs in the workers container
tail -f log/development.log

Other Tasks

Bulk delete by collection

Add to OD2 lib/tasks/migration/bulk_delete.rake and set batch_name to a folder name inside the path defined at config.ingest_local_path (defaults to /data/tmp in config/initializers/hyrax_migrator.rb) in OD2.

Example

When batch_name is batch_baseball, the task bellow will scan bags at /data/tmp/batch_baseball to get the PIDs, and then remove them from the system.

/data/lib/tasks/migration/bulk_delete.rake

# frozen_string_literal: true

namespace :migration do
  desc 'Bulk delete migrated items'
  task bulk_delete: :environment do
    batch_name = 'batch_baseball'
    begin
      file_name = "bulk-delete-migrated-#{Date.today}.log"
      logger = Logger.new(File.join(Rails.root, 'log', file_name))
      puts "Delete works already migrated at #{batch_name}"
      c = Hyrax::Migrator::Configuration.new
      batch_path = File.join(c.ingest_local_path, batch_name)
      bag_zip_files = Dir.entries(batch_path).select { |e| File.file?(File.join(batch_path, e)) && File.extname(e) == '.zip' }
      bag_zip_files.each do |zip_file|
        pid = File.basename(zip_file, File.extname(zip_file))
        puts "Deleting work #{pid}"
        gid = ActiveFedora::Base.find(pid).to_global_id.to_s if ActiveFedora::Base.exists?(pid)
        Sipity::Entity.find_by(proxy_for_global_id: gid).delete if Sipity::Entity.find_by(proxy_for_global_id: gid).present?
        ActiveFedora::Base.find(pid).delete if ActiveFedora::Base.exists?(pid)
        ActiveFedora::Base.eradicate(pid)
        Hyrax::Migrator::Work.find_by_pid(pid).delete if Hyrax::Migrator::Work.find_by_pid(pid).present?
        logger.info("Successfully deleted #{pid}")
      end
      puts "Done"
    rescue StandardError => e
      puts "Unable to delete #{pid}"
      puts "Error: #{e.message}"
      puts e.backtrace
      logger.error "Unable to delete #{pid}: #{e.message}: #{e.backtrace}"
      return nil
    end
  end
end
