Can someone explain why we should use NFS? It is fairly slow and unsecure.

Why not use some clustered FS ? 

Are there alternatives ?

This list shows that you have no clue what you are doing. iSCSI is a
transport protocol. gfs and ocfs2 are filesystems.

Stick with NFS. Cluster filesystems are complex and fragile beasts. As
long as you don't need it for scalability reasons, it does not provide
you much gain.
