Introduction

CTDB is a clustered database component in clustered Samba that provides a high-availability load-sharing CIFS server cluster.

The main functions of CTDB are:

  • Provide a clustered version of the TDB database with automatic rebuild/recovery of the databases upon node failures.
  • Monitor nodes in the cluster and services running on each node.
  • Manage a pool of public IP addresses that are used to provide services to clients. Alternatively, CTDB can be used with LVS.

Combined with a cluster filesystem CTDB provides a full high-availablity (HA) environment for services such as clustered Samba, NFS and other services.

Supported platforms

CTDB is primarily developed and tested on Linux. A subset of features may work on other platforms.

Getting and Building CTDB

Samba and CTDB must be installed on all nodes of a cluster. CTDB is part of Samba (>= 4.2.0), so to get CTDB you need to get Samba.
