Our cluster got into really bad shape in production, probably because of too many shards. 45k shards in 5 data nodes.

I have tried a few things and seems to help that includes restarting the node (make sure there is no data loss). Right now, I see about 15k unassigned shards, but these unassigned hsards are recovering so slow that it will probably take days to recover.

I know there is a delay set for allocation of unassigned shards when a node leaves as mentioned [here](https://www.elastic.co/guide/en/elasticsearch/reference/1.7/delayed-allocation.html), but that's not helping here.

Is there a way to speed up allocation of unassigned shards with all nodes up? We have 2 replicas for all indices.
