Thanks David ! All my "Recovery Throttling settings" are default in the elasticsearch.yml file. How do I disable allocation, in a running production environment ? Do I need to disable allocation first, restart each node / daemon, and after rename the nodes ?
Or maybe it would be better to down the ES cluster (all 3 nodes) during a maintenance windows, change all names, and then restart the ES cluster nodes again ? //Jan-Erik Den onsdag 18 februari 2015 kl. 16:18:42 UTC+1 skrev David Pilato: > > Yes.
