[Linux-cluster] Redhat GFS 6.1 for sharing same storage from 4 nodes without High availability

[Jonathan E Brassow]

Yes, you can use GFS for this.

What you are most likely concerned about in this case is coherency (and 
a file system that can tolerate multiple machines mounting).  Note that 
just because GFS is cluster-aware and won't corrupt itself, doesn't 
mean your applications are suitably cluster-aware.  A first question 
you could ask yourself is, "Could I run multiple copies of my 
application on the same node successfully?"  If the answer is yes, then 
you can probably run multiple copies of your app on different machines 
when using GFS.
