Thank you to open a case for my request.
I have though one thing unclear: in a cluster that contains for example 2 blades I have the same app deployed on both payloads - otherwise I do not see why they would be in a cluster - at least that is my understanding of having a cluster.
With that in mind, I do not see why the deployments && configuration directories could not be shared over a NFS mounted drive rather than having them defined per blade !
Right now I cannot have them shared because the standalone.xml is written by the instance running on each blade (+ the history, etc ...) && the deployments directory contains extra files as ".undeployed" etc .....
Duplicating the same data for me on different blades is error prone not to say that it requires extra handling. Especially if one has a 40 blade system .... there would be 40 copies of the same data across every blade which to me sounds redundant.
That would require some more changes and I do not know if one would agre with me.
