Setting up a simple CTDB Samba cluster
As of April 2007 you can setup a simple Samba3 or Samba4 CTDB cluster, running either on loopback (with simulated nodes) or on a real cluster with TCP. This page will tell you how to get started.
Getting the code
You need two source trees, one is a copy of Samba3 with clustering patches, and the other is the ctdb code itself. Both source trees are stored in bzr repositories. See http://bazaar-vcs.org/ for more information on bzr.
The fastest way to checkout an initial copy of the Samba3 tree with clustering patches is:
rsync -avz samba.org::ftp/unpacked/samba_3_0_ctdb .
To update this tree when improvements are made in the upstream code do this:
cd samba_3_0_ctdb bzr merge http://samba.org/~tridge/samba_3_0_ctdb
To get an initial checkout of the ctdb code do this:
rsync -avz samba.org::ftp/unpacked/ctdb .
To update this tree when improvements are made in the upstream code do this:
cd ctdb bzr merge http://samba.org/~tridge/ctdb
Building the Samba3 tree
To build a copy of Samba3 with clustering and ctdb support you should do this:
cd samba_3_0_ctdb/source ./autogen.sh ./configure --prefix=/gpfs0/samba/prefix --with-ctdb=/usr/src/ctdb --with-cluster-support --enable-pie=no make proto make
You should replace the /gpfs0/samba/prefix path with the cluster shared storage path you will use to install Samba. The path should to be a directory that is the same on all nodes of the cluster. If you are setting up a virtual cluster on loopback then this can be any local directory.
The /usr/src/ctdb path should be replaced with the path to the ctdb sources that you downloaded above
Building the CTDB tree
To build a copy of the CTDB code you should do this:
cd ctdb ./autogen.sh ./configure make
Installing Samba3
To install Samba3 you should do this:
cd samba_3_0_ctdb/source make install
Then you need to configure an appropriate smb.conf. There is a very simple example in samba_3_0_ctdb/examples/ctdb. You need to put this smb.conf in the lib/ subdirectory of the prefix you chose above.
Next you need to initialise the Samba password database. Something like
smbpasswd -a root
will do that. Samba with clustering must use the tdbsam or ldap SAM passdb backends (it must not use the default smbpasswd backend). The rest of the configuration of Samba is exactly as it is done on a normal system. See the docs on http://samba.org/ for details.
