Hello,  
This topic has been discussed in-depth, and I am still looking for a better understanding. So hoping someone can provide insights.

How do we actually allocate storage to a shard? I know we can increase number of shards, but I am interested in resizing a shard. For example, if i want to increase size of my 10 shards (from 10GB to 15GB) for an index, what is the best approach?

Thanks!  
Hamid

If you are using ILM then you can limit the size of the index - and hence the shards. Otherwise it's a more of a logical concept, and you cannot directly limit the size of a shard.
