We are storing files on a network share, our application is mountig this drive using nfs. Now we have the requirement to have this drive redundant.
We can add a second server and then synchronize the direcory with this server. What are the best approaches to do the synchronisation?
If one server is out of order, how can we do the failover? Is there a way in nfs to specify a backup drive and nfs is automatically getting the data from the backup drive? If this is not possible with nfs, is there another filesystem which supports something like that?
