Elasticsearch data folder size

(sri) #1

am running elasticsearch cluster for elk
with 1master 1client and 1 data node
(5shards and 1 replica)
mounted the volumes under /data directory in the es containers.
i allocated 20 gb volume for each
but when the cluster is formed if i see the usage in /data
bash-4.3# df -h /data
Filesystem Used Available Use% Mounted on
Size 160.3G
Used 70.3G
Availabel 81.8G
Use% 46%
Mounted on /data

why is the use% 46 at the initial stage itself when there are no indexes created yet

pls clarify
