Extend content capacity for an existing deployment (FAST Search Server 2010 for SharePoint)

FAST Search Server 2010
 

Applies to: FAST Search Server 2010

Topic Last Modified: 2011-04-05

A default Microsoft FAST Search Server 2010 for SharePoint indexer configuration is optimized for content volumes up to 15 million items per index column. You can change the indexer configuration to handle up to 40 million items per column.

warningWarning
Before you change the configuration, you must first remove all indexed content from your FAST Search Server 2010 for SharePoint farm. Depending on the size of your deployment, it may take days or even weeks to re-index the content.


Before you extend the content capacity, read the Index capacity tuning recommendations.

To extend content capacity for a deployment with indexed content
  1. Stop crawling:

    1. If you use the FAST Search Content SSA to crawl content, see Start, pause, resume, or stop a crawl (FAST Search Server 2010 for SharePoint) for information about stopping a crawl.

    2. If you use the FAST Search Web crawler to crawl content, see Start, suspend, resume, or stop a crawl process (FAST Search Web crawler) for information about stopping a crawl.

    3. If you use the FAST Search database connector to crawl content, see Test, start or stop a crawl (FAST Search database connector) for information about stopping a crawl.

    4. If you use the FAST Search Lotus Notes connector to crawl content, see Test, start or stop a crawl (FAST Search Lotus Notes content connector) for information about stopping a crawl.

  2. Pause the Web Analyzer components. These components analyze links between items and search clickthrough logs. The components must be stopped to avoid partial updates for indexed items during the procedure.

    1. On the administration server, open a FAST Search Server 2010 for SharePoint shell.

      1. Verify that you meet the following minimum requirements: You are a member of the FASTSearchAdministrators local group on the server where FAST Search Server 2010 for SharePoint is installed.

      2. On the Start menu, click All Programs.

      3. Click Microsoft FAST Search Server 2010 for SharePoint.

      4. Click Microsoft FAST Search Server 2010 for SharePoint shell.

    2. Inspect the Web Analyzer schedule status:

      waadmin ShowStatus
      
      noteNote
      Refer to waadmin.exe reference if you use multiple views for the Web Analyzer.

      In the Views section of the command output, for the default view, inspect the Schedule status.

      1. If the Schedule status is set to paused, type the following command:

        waadmin enqueueview
        
      2. Wait until the default Web Analyzer view is running. Type the command waadmin ShowStatus and inspect the Schedule status. The Schedule status should be set to running.

    3. Stop Web Analyzer processing:

      waadmin AbortProcessing
      spreladmin AbortProcessing
      
  3. Wait until all item processing is finished:

    psctrl status
    

    Repeat the command until all processor servers report "idle".

  4. Remove all items from the content index:

    1. If you use the FAST Search Content SSA to crawl content, follow the steps in Reset the content index (FAST Search Server 2010 for SharePoint) to remove all items from the default content collection named "sp".

    2. If you use the FAST Search Web crawler to crawl content, follow the steps in Reset the content index (FAST Search Web crawler) to remove all items from the content collection or collections that are associated with this connector.

    3. If you use the FAST Search database connector to crawl content, follow the steps in Reset the content index (FAST Search database connector) to remove all items from the content collection or collections that are associated with this connector.

    4. If you use the FAST Search Lotus Notes connector to crawl content, follow the steps in Reset the content index (FAST Search Lotus Notes connector) to remove all items from the content collection or collections that are associated with this connector.

  5. Make sure that no items are indexed on any of the indexers:

    On the administration server, type the following command:

    indexerinfo -a doccount
    
    noteNote
    All indexers must report 0 items before you proceed to the next step.
  6. Change the index partition configuration:

    1. On the administration server, locate the indexer template configuration file:

      <FASTSearchFolder>\META\config\profiles\default\templates\installer\etc\config_data\RTSearch\clusterfiles\rtsearchrc.xml.win32.template

      Where <FASTSearchFolder> is the path of the folder where you have installed FAST Search Server 2010 for SharePoint, for example C:\FASTSearch.

    2. Save a backup of the file. You may need the backup at a later stage if the configuration file is modified in a software update.

    3. In a text editor, open the file and change the following configuration parameters:

      • numberPartitions:

        Default value: 5

        New value: 10

      • docsDistributionMax:

        Default value:

        6000000,6000000,6000000,6000000,6000000

        New value:

        6000000,6000000,6000000,6000000,6000000,6000000,6000000,6000000,6000000,6000000

  7. Re-deploy the farm configuration to all servers:

    importantImportant
    In this step, you must change the deployment configuration file (deployment.xml) without changing the actual content. You can do that by adding a space and then save the file.

    Follow the steps in Reconfigure the deployment including adding new servers.

  8. On the administration server, run the following commands to resume processing for the Web Analyzer components:

    waadmin EnqueueView
    spreladmin Enqueue
    
  9. Start a full crawl of all content:

    1. If you use the FAST Search Content SSA to crawl content, see Start, pause, resume, or stop a crawl (FAST Search Server 2010 for SharePoint) for information about starting a crawl.

    2. If you use the FAST Search Web crawler to crawl content, see Start, suspend, resume, or stop a crawl process (FAST Search Web crawler) for information about starting a crawl.

    3. If you use the FAST Search database connector to crawl content, see Test, start or stop a crawl (FAST Search database connector) for information about starting a crawl.

    4. If you use the FAST Search Lotus Notes connector to crawl content, see Test, start or stop a crawl (FAST Search Lotus Notes content connector) for information about starting a crawl.
