Rebuilding a Database (BDB, HDB)

Sometimes it is necessary to rebuild a backend database. This process differs depending on the database backend. For instance, with a SQL backend, it might entail dumping, dropping, and re-creating tables in the database.

Note

Moving to a new server and transferring contents to a new slave server are also processes similar to rebuilding a database, and the differences are mentioned within the text here.

The most commonly-used backends for OpenLDAP are the HDB and BDB backends (both based on the Berkeley DB lightweight database). In this section, I want to cover the process of rebuilding these databases.

This process consists of five steps:

  1. Stop SLAPD
  2. Dump the directory data into a file
  3. Delete the old directory files
