Hi,  
I brought up a single node ES cluster and the heath status is being  
reported as Red. Any pointer on how to fix this?

{

- cluster\_name: elasticsearch
- status: red
- timed\_out: false
- number\_of\_nodes: 1
- number\_of\_data\_nodes: 1
- active\_primary\_shards: 1922
- active\_shards: 1922
- relocating\_shards: 0
- initializing\_shards: 0
- unassigned\_shards: 1950

}

Best Regards,

Ram Viswanadha

You have created quite a lot of shards, do you see any failures in the logs?
