Ariz,

Using rsync from the master to the slave node
is not a good thing.

rsync is good for transferring static or closed
files, but transfering open files... you could
be transmitting files in various inconsistent
state. Unless you run rsync every minute...
and that may not even help you at all.

What can be done is that the two box is sharing
the same Disk Array. But only one box can access
it at the same time. And maybe add a script to
the 2nd box to do the failover and check the
disk array by using fuser, df, or mount, etc.
before truly mounting the disks on the shared
disk array.

As an alternative, Ian mentioned drbd.
