For active-active Samba on Linux, the only setup I know of is the Red Hat
Cluster using GFS over a SAN

For active-passive, DRBD works great and the price is right

If you really want active-active, be prepared to spend a lot ;-). Also, be 
extremely sure you know exactly what you're buying. HA terminology tends to 
vary in meaning from vendor to vendor. For example, Steeleye has what they 
call an active-active cluster, but what they mean by that is something 
conceptually like:

* node1 is running Samba
* node2 is running Apache
* if either node dies, both apps run on the other node
