File system replication between servers

Does anyone know of any software that will run on FreeBSD that would allow 
you to keep two servers in sync?  All writes to /dir1 on server1 would go 
to /dir1 on server2, and all writes to /dir2 on server2 would go to /dir2 
on server1?

I've thought about rsync, but am trying to get it as close to real time as 
I can, and on large file systems, rsync would just get too far behind, too 
quickly ...

I've started to look at Coda6, but so far what I'm reading through the 
docs makes it sound like it may not be suitable ...

What I'm looking for is a hot failover solution using FreeBSD ... if 
server1 goes down, server2 can start up and continue working ... when 
server1 comes back up again, changes to server2 could be re-sync'd back to 
server1, and server1 could once more resume its duties ...

Thanks ...
