Enabling and Disabling Multiple index locations support for Elasticsearch index volumes

Description

This article contains information about enabling and disabling multiple index locations support for Elasticsearch index volumes in Enterprise Vault 15.0 and greater.

Enabling ‘Multiple index locations support for Elasticsearch index volumes’

By enabling multiple index locations support for Elasticsearch index volumes, you will be able to utilize multiple Elasticsearch index locations.

To enable multiple index locations support for Elasticsearch index volumes, follow the steps mentioned below:

1. Stop the Enterprise Vault Indexing Service.
2. In the Administration Console, expand the Enterprise Vault site until the Enterprise Vault Servers container is visible.
3. Expand the Enterprise Vault Servers container.
4. Right-click the name of the Enterprise Vault server and select the Properties menu option.
5. Open the Advanced tab and select Indexing from the drop-down menu.
6. Select the Multiple index locations support for Elasticsearch index volumes setting and click the Modify button.
7. Change the setting from Off to On and click OK.
8. Click Apply/OK to save the changes.
9. You can now configure multiple Elasticsearch index locations for Elasticsearch Index volumes. To configure multiple index locations, open the Elasticsearch Index Locations page from the Enterprise Vault Indexing Service properties. You will be able to see the existing index location configured, which you may wish to use. Add/Remove the index locations as per the requirement and save the changes.
10. Start the Enterprise Vault Indexing Service.

Disabling ‘Multiple index locations support for Elasticsearch index volumes’

By disabling multiple index locations support for Elasticsearch index volumes, you can provide only one Elasticsearch index location.

After disabling the multiple index locations support, you must copy all the data from all the existing Elasticsearch index locations to a new Elasticsearch index location that you are going to use. Once the disabling process of multiple index locations is completed, existing Elasticsearch index locations will not be used.

To disable multiple index locations support for Elasticsearch index volumes, follow the steps mentioned below:

1. Stop the Enterprise Vault Indexing Service.
2. In the Administration Console, expand the Enterprise Vault site until the Enterprise Vault Servers container is visible.
3. Expand the Enterprise Vault Servers container.
4. Right-click the name of the Enterprise Vault server and select the Properties menu option.
5. Open the Advanced tab and select Indexing from the drop-down menu.
6. Select the Multiple index locations support for Elasticsearch index volumes setting and click the Modify button.
7. Change the setting from On to Off and click OK.
8. Click Apply/OK to save the changes.
9. You can now configure a new Elasticsearch index location for Elasticsearch Index volumes. To configure the new index location, open the Elasticsearch Index Locations page from the Enterprise Vault Indexing Service properties. Provide a new index location and save the changes.
10. Create the nodes\0\indices folder hierarchy under the new Elasticsearch index location.
11. You can get path details of all the existing index locations from the Event Viewer. Look for the event ID <3510> and make a note of all the index locations mentioned in the event.
12. Copy all the data from all the existing index locations to the new Elasticsearch index location (<New Index Location Path>\nodes\0\indices). Follow the steps below for each of the existing index locations:
    1. Go to <Existing Index Location Path>\nodes\0\indices. Copy all the data from this folder.
    2. Go to <New Index Location Path>\nodes\0\indices and paste the copied data into this folder.
    3. Repeat the above two sub-steps (sub-steps 1 and 2) for each of the existing index locations configured.
13. Start the Enterprise Vault Indexing service.
