Problem solved. reroute every failed shards in index.  
Here is the exam;  
POST /\_cluster/reroute  
{  
"commands" : [ {  
"allocate" : {  
"index" : "index\_name",  
"shard" : 4,  
"node" : "node\_name",  
"allow\_primary": true  
}  
}  
]  
}

That won't reindex the data, it'll (likely) just create a new, but empty shard.

Reindex your data using the same method you used to initially index it.
