Introduction

A Namespace Database, or NSDB, is the repository for fileset location information in a FedFS domain. At its core, an NSDB is simply an LDAP server with an NSDB Container Entry, or NCE, for short. FedFS data is stored as children of this entry.

In this article, we introduce several simple command line tools that can be used to manage and troubleshoot an NSDB.

Installing or building the NSDB admin tools

• Installing or building fedfs-utils-0.8

Additional instructions

Instead of installing the whole package, you may choose to install just the the NSDB admin tools:

# (cd fedfs-utils-0.9/src/nsdbc ; make install)

And install the nsdbparams command:

# (cd fedfs-utils-0.9/src/nsdbparams ; make install)

Simple queries

First, create an entry for your NSDB in your admin host's NSDB connection parameters database:

# nsdbparams update -D cn=Manager -e ou=fedfs,dc=example,dc=net ldap.example.net

The NSDB hostname is almost always a parameter of each NSDB admin tool. To save yourself some typing, you can set up an environment variable containing the name of the NSDB you'll be working with.

$ export FEDFS_NSDB_HOST="ldap.example.net"

Now, see what NCEs exist on your NSDB:

$ nsdb-nces

This command should tell you which naming contexts host an NCE. You should see the NCE you created above. There should be no FedFS records yet, but you can confirm that with:

$ nsdb-list
