Can we use fsriver plugin to index remote directory. Suppose we have 4 Linux machine on same network and can access each other. I have fsriver installed on node[1,2] and elastic search on[1,2] for failover. If i create a new index for folder //node3/temp, can fsriver index this folder if i can access this folder from both node[1,2]. or can mount a directory as shared between all the nodes.
