Hi,  
I have Heterogeneous machines in my cluster , some of them with smaller disk and some with larger.  
What will happen if one of the machines will run into situation where no more space left on disk ?

Thanks

Generally elasticsearch will start pushing shards off of the node when it  
gets close to full. You can use allocation properties (set on node and on  
index) to help with heterogeneous cluster.

Yes. The disk watermarks are 1.2ish. I don't remember off hand but you  
certainly have them.
