The High Availability chapter of the Samba HOWTO is a great place to start. http://us1.samba.org/samba/docs/man/Samba3-HOWTO/SambaHA.html For reasons cited there, your best bet is an active/standby cluster configuration. With this setup you'd have two servers up and running, but only one of them would be serving files with Samba. In the event of a problem with the Samba server, the standby server would take over and begin serving the files. There are various programs that can be used to help automate the failover. It is worthwhile to note that during failover SMB connections will be lost and will have to be reestablished. With newer Windows clients the reconnection will typically occur automatically though any open files will likely be closed. The loss of connections would occur even in an active/active configuration though only half of the clients (those connected to the failing server) would be affected.
