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?
