hi all,
please provide me some solution asap
i have some indexes on local files at my server.after shutdown and restart

I'm afraid you can not get back your documents.
As far as understand your problem:
You have one node with x docs.
You have node two running with 0 docs but with the same clustername.
You stop node1 and start it again.
So your node1 recognize your node2 which is a master node and told to node1 that
there is 0 docs in the index.
So, node1 delete all remaining index/docs.
One thing you can try is to stop node1. Then to stop node2.
Then start node1 and see if you get back your docs.
Try to see the size of your node1 data dir to see if documents remains here.
If your dir is almost empty, you won't recover your docs.
My 2 cents.
David.

I have all my indices file intact in my local file system [38gb size] but
my production node does not recognize indices and throws dangling index
problem.

So, first, backup theses files.
Then, is the dirname under data is the same as your cluster name ?
What happens if you only start your local node?
Can you see your index and documents?

no i cant see my indices all of them become dangling as soon as i start
production node.i did recovery from backup i made of whole cluster which
saved me from disaster production node recognized the indices from the rar
backup.but can some one explain me the fundamentals of \_state files in
cluster and the shards?
