At the moment we have 3 Elasticsearch-Node (All Master)
Each Elasticsearch-Node is installed on a Ubuntu-VM on our central ESXi-Cluster.
Each node has a dedicated /data mount to store the Data on a own volume in our SAN.
The current default for our indices is 1 Replica.
So i thought about one Central data-store for all nodes, so i could reduce the storage Size by the half because each shard is not stored 2x on different data-volumes.
I found the setting for that in the documentation:
So its possible and (at the moment) supported.
But did "This setting is deprecated in 7.x and will be removed in version 8.0" mean that in 8.0 it wouldn't be supported anymore or just you don't need to set this attribute?
And why its not recommend by Elastic, what are possible downsides?
Thanks in Advice,
