Chapter 11. Clustered Samba Configuration
The Red Hat Enterprise Linux 6.2 release provides support for running Clustered Samba in an active/active configuration. This requires that you install and configure CTDB on all nodes in a cluster, which you use in conjunction with GFS2 clustered file systems.
This chapter describes the procedure for configuring CTDB by configuring an example system. For information on configuring GFS2 file systems, refer to Global File System 2. For information on configuring logical volumes, refer to Logical Volume Manager Administration.
CTDB is a cluster implementation of the TDB database used by Samba. To use CTDB, a clustered file system must be available and shared on all nodes in the cluster. CTDB provides clustered features on top of this clustered file system. As of the Red Hat Enterprise Linux 6.2 release, CTDB also runs a cluster stack in parallel to the one provided by Red Hat Enterprise Linux clustering. CTDB manages node membership, recovery/failover, IP relocation and Samba services.
