Hi , I'm getting this error in Kibana

Elasticsearch is still initializing the kibana index... Trying again in 2.5 second

and the .kibana index is the only index in red mode

any suggestions without losing all data ?

ELK stand alone server :


-bash-4.1# curl http://localhost:9200/_cluster/health?pretty
{
  "cluster_name" : "elasticsearch",
  "status" : "red",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 1770,
  "active_shards" : 1770,
  "relocating_shards" : 0,
  "initializing_shards" : 0,

What is the output from _cat/indices/kibana*?v?

Unfortunately you have a single node with no replica, so unless you have a backup of the Kibana index, you have likely lost it.

You have nearly 1800 shards on a single node. That is not good at all and is causing you problems with cluster stability and all those unassigned shards. You need to look at reducing that shard count to at least a third of the current size.
