Hi,

The following configuration seems to do what you ask for:

Two NFS servers, each of them provides access to a huge equal-sized
file-container.
Third server mounts directories with files-containers from the
prevoius two servers.
GEOM RAID1 mirroring is used on the third server to create a /home
filesystem backed by two huge file-containers.

You will have a copy of your /home inside the GEOM file-container on
each of the two servers.
You will get realtime data replication.

Drop a note if the performance of such configuration is acceptable :)

Best regards,
EforeZZ
