Check that no plugin applications are using the index before deleting it.

Note:

When the index is deleted, the corresponding index database is also deleted. The disk space is reclaimed after the cleaner threads begin.

  • To remove an index from the database, run dsconfig with the delete-local-db-index option. 
    $ bin/dsconfig delete-local-db-index \ 
  --index-name roomNumber --backend-name userRoot
