Hi,

I am facing shard failure issue because of lack of space. However I noticed that the in some indexes the deleted count was more than 20%.  
As per the Elastic Search documentation, segment merging will happen if deleted count crosses the 10% of total records. But currently this is not happening.  
Anybody know why this is not getting merged?

ES version : 5.4.1  
RAM : 60GB  
HDD : 2TB SSD  
CPU : 8core

Thanks,  
Nilesh
