Hi, I am using ES 0.90.13 with 10 clusters. Java Sun 1.7.53. We find out that the # of replicas on our ES clusters was zero. Hence, we increased the # of replica last week on ES2 to 1. Since then the cluster became yellow \<-\> green. It runs fine for several hours and then became yellow (with X unassigned shards). After few hours it became green. Most of the time it became green, but from time few time it is stacked on 2 unassigned shards. From the logs: [index.shard.service] [es2-s01] [ds77777][3] suspect illegal state: trying to move shard from primary mode to replica mode [2014-08-11 00:33:10,384][WARN][cluster.action.shard] [es2-s02] [ds6765431\_1\_s][1] sending failed shard for [ds6765431\_1\_s][1], node[M34ta1aGTv-S4ahkrXK5DA], [R], s[STARTED], indexUUID [4T8zV8r7RUu8UkvQYsoz3w], reason [master [es2-s03][4rJC0nkVR1SgZhAcOK2MZw][inet[/10.1.112.3:9300]]{data\_center=ny4, max\_local\_storage\_nodes=1, master=true} marked shard as started, but shard has not been created, mark shard as failed] This is a producation cluster.
