Hello Aiman Aidil,

Shared storage in a cluster would serve the purpose of a centralized pool where your application (in your case apache) lives and that can be accessed by all nodes at any given time. If you wish to implement something outside of this then how would your application tolerates a node failure? The main purpose of HA is to sustain/tolerate a node failure where application is running and which could migrate to healthy node when this happens. Please explain...
