Getting and Building CTDB

From SambaWiki

Getting CTDB Source code

If you download source code for Samba >= 4.2.0 then CTDB is included in the ctdb subdirectory.

Binary packages

  • Your operating system may include pre-built packages for Samba and CTDB
  • If you use pre-built packages then you need to ensure that Samba was built with cluster support
You can get information about smbd's clustering features:
  # smbd -b | grep -i 'ctdb\|cluster'
  Cluster support features:
    CTDB_SOCKET: /var/run/ctdb/ctdbd.socket
Note that output may vary slightly, but the CLUSTER_SUPPORT feature must be present.
  • CTDB will usually be in a separate package to other Samba components called ctdb

Building from source code

CTDB should be built with Samba. Add the following options to the ./configure command.

This enables clustering support in Samba and includes CTDB in the build
Clustered Samba needs an IDMAP facility so it is worth building a few

Other than that, just follow instructions for building Samba.

Legacy CTDB versions

You should use a version of CTDB that comes with a supported Samba version.

However, legacy, standalone versions of CTDB are still available (including 2.x). These versions were used with Samba versions older than 4.2.0.

The code is also available from the CTDB git repository at git:// See also the GIT web interface.
