ElasticSearch update[edit]

1. Backup elasticsearch data directory 

 sudo service elasticsearch stop
 sudo tar cfz var_lib_elasticsearch_$(date +%y%m%d).tgz  /var/lib/elasticsearch
 sudo service elasticsearch start

2. Check that ES is up and running, and note the results: 

 curl -X GET "localhost:9200/_cat/indices?v"
 health status index     pri rep docs.count docs.deleted store.size pri.store.size 
 yellow open   aips        5   1      24816            1    175.4mb        175.4mb 
 yellow open   transfers   5   1          0            0       720b           720b

Check also if there are any configured snapshot: 

 curl -XGET "localhost:9200/_snapshot/_all?pretty"

3. Remove Snapshots

If there are any snapshot (step 1), please remove it: 

 curl -XDELETE "localhost:9200/_snapshot/backup-repo?pretty"

4. Stop elasticsearch service 

 sudo service elasticsearch stop

5. Check wich elasticsearch version is installed 

 Redhat/Centos: rpm -q elasticsearch
 Ubuntu: dpkg -l elasticsearch

6. Download a temporary copy of elasticsearch (same version than intalled) 

 wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.6.tar.gz


7. Uncompress the downloaded tar.gz and go into it 

 tar zxvf elasticsearch-1.7.6.tar.gz
 cd elasticsearch-1.7.6


8. Copy data from system wide installed elasticsearch, ot the temporary copy 

 sudo cp /var/lib/elasticsearch data -rf

9. Adjust file permissions 

 sudo chown <your user>:<your group> data -R

10. Launch the temporary elasticsearch instance 

 ES_JAVA_OPTS="-Xms2g -Xmx2g" ./bin/elasticsearch -d -p elastic-tmp.pid -Des.http.port=9500  -Des.discovery.zen.ping.multicast.enabled=false

11. Verify that the indexes were properly copied. Use the port specified in the previous command: 

 curl -X GET "localhost:9500/_cat/indices?v"

12. Remove elasticsearch 1.7.6 and it's files 

 Redhat: sudo yum remove elasticsearch
 Ubuntu: sudo apt-get remove --purge elasticsearch
 sudo mv /var/lib/elasticsearch /var/lib/elasticsearch-1.7.6
 sudo mv /etc/elasticsearch /etc/elasticsearch-1.7.6

13. Upgrade archivematica and install elasticsearch 6 

 ansible-playbook -i hosts singlenode.yml --tags=elasticsearch,archivematica-src

14. Configure ElasticSearch 6 to handle reindex from the temporary es 

 echo 'reindex.remote.whitelist: localhost:9500' | sudo tee -a /etc/elasticsearch/elasticsearch.yml
 sudo service elasticsearch restart

15. Migrate the indexes 

 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 reindex_from_remote_cluster -t 60 -s 1 http://localhost:9500
 ";

The command should finish with 

 All reindex requests ended successfully!

Else, you might need to tweak the timeout (-t) and size (-s) parameters.


16. Verify that the new indexes were created and populated: 

 curl -X GET "localhost:9200/_cat/indices?v" 
 health status index         uuid                   pri rep docs.count docs.deleted store.size pri.store.size
 yellow open   transferfiles jlu2d2yZQpWwpKKT1ZzMAA   5   1          0            0      1.1kb          1.1kb
 yellow open   aips          VAvONAByRBuVcWBYhlhUmw   5   1        116            0     66.9mb         66.9mb
 yellow open   transfers     OhfLVBzuRqCNUYRCSSTidg   5   1          0            0      1.1kb          1.1kb
 yellow open   aipfiles      clX1gcqnT9CTdwTm8jeatw   5   1      24700            0     70.6mb         70.6mb

You should have 4 indexes now, and the sum of the aips and aipfiles docs.count column should be equal to the doc.count for the aip index in ElasticSearch 1.7.6. The same happens with the transfers/transferfiles indexes.

17. Stop the temporary elasticsearch service 

 kill $(cat ~/elasticsearch-1.7.6/elastic-tmp.pid)

18. Restart all archivematica services 

 sudo service archivematica-mcp-server restart
 sudo service archivematica-mcp-client restart
 sudo service archivematica-dashboard restart
 sudo service archivematica-storage-service restart
