Unavailable Shards Exception Not enough active copies to meet write consistency of [QUORUM] (have 1, needed 2)

Hi All,

We are using ES version 1.7.2 in Production cluster. ES cluster has 3 different physical servers.

We have 3 indices such as es_chr, es_cval & es_item
Sync job is running everyday for all indices. Yesterday during sync process we have got the following error in log table,

{"took":60005,"errors":true,"items":[{"index":{"_index":"es_item","_type":"item","_id":"4147177","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4152883","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4184942","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4184965","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4213047","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4250468","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4252967","_version":3,"status":200}},{"index":{"_index":"es_item","_type":"item","_id":"4258221","_version":3,"status":200}},{"index":

Some of the items were indexed properly but some items were failed to do so.

Is there any reason Why I am getting an error during sync job process?

Please kindly help me this..

Are you specifying write consistency?
How many replicas do you have?

No @warkolm I didn't use write consistency.

I have given replica as "2"
