CTDB and Clustered Samba
Revision as of 09:47, 2 February 2023 by Slowfranklin (talk | contribs) (→Configuring Clusters with CTDB)
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.
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.
Configuring Clusters with CTDB
- Basic CTDB configuration
- Setting up a cluster filesystem
- Configuring the CTDB recovery lock
- Adding public IP addresses
- Configuring clustered Samba
- Setting up CTDB for Clustered NFS
- Setting up CTDB with other services
- Advanced CTDB configuration
- CTDB with GPFS
- CTDB with GlusterFS
- CTDB with GFS
