comment NFS Caching Issue
Need to restart the server process unless your application can be triggered to close open files & clear application caches. Many web frameworks that have caching functionality have something like that, e.g. symfony cc or drush cc all

comment NFS Caching Issue
Since Linux NFS client has close-to-open cache consistency you need to make sure that the files are closed and reopened by the webserver as soon as the deployment is complete.

comment NFS Caching Issue
What happens when you manually open a newly deployed file on a web server before clearing the NFS caches? Do you see the old or updated version. How do you deploy, @rsync@ or anything else? What are the mount options? AFAIK it is not supposed to behave like that.

comment Shared Disk in modern data center (SAN, virtualization, etc)
+1 for object storage. Looks like that is the core of the question, i.e. scalable storage of irregular chunks of data.

comment NFS client does not pick up server after restart
I was thinking of the grace period in Solaris NFS daemons. That is usually within 1 minute. I guess your NFS server is also a Debian server.

comment Possible to connect multiple InfiniBand switches?
Could you add more details of your setup by editing your question? What kind of switches do you have, what kind of cabling, what sort of hosts and HCAs, how do you check if the fabric is continuous?

comment NFS client replaces some remote folders with local folders
The thing about symbolic links doesn't seem clear enough could you add to your post the output of ls -l /home/MyUser/work and ls -l /nfs_share/work on the client?

Welcome to serverfault.com! This sounds like a shell scripting problem to me.

Since you are asking about home directories, how is your user account info distributed, is there anything resembling an ldap tree spanning the whole org?

comment Server restart cause
If it's a faulty capacitor in the PSU the frequency of restarts should gradualy increase with the time. Also do the restarts happen randomly during the day or close to specific time? Is the machine brand new?

comment Server restart cause
Anything. Computing md5sum of your filesystem or dd if=/dev/urandom of=/dev/null for instance. Just to see if higher load would cause a reboot.

comment Server restart cause
PSU might be the cause or memory, or few other options. Try to load it with some CPU-heavy or I/O heavy task. See if it would restart under load.
