I've set up a Linux file server for the municipal offices of my town (as a volunteer consultant and Linux evangelist).

The intent is that if one goes down, the other one will take over with little or no lost data and the shift will be imperceptible to the network users.
What software should I be looking at to accomplish this?

Two packages you might want to take a look at are rsync for duplicating data between machines and heartbeat for detecting if a machine goes does down (for auto fail over I think). There is another package for syncing two machines in near real time, it treats the second as a block device for data backup, but I can't remember the name of the package (old age setting in I think but I can't remember). -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998
