Hi,  
Im wondering if there is option to save Elastic from getting above 90% disk space..  
I have ILM policy set to rollover new index every 50 GIGA and Delete phase for 30 Days. i have 10 Tera disk space on my Cluster...  
My data amount is different from day to day and sometimes i need to delete indices manually because Elastic doesn't have enough disk space.  
Is there any idea for manage that ?  
Retention policy maybe?
