I use k8s built a ela cluster, I in the yaml document data directory: / usr/share/elasticsearch/data local hostpath path is: / data/elasticsearch/data - This is directory permission information: drwxr-xr-x. 3 1000 1000 18 Feb 22 11:25 elasticsearch What if we solved this problem, because we now have one data directory mounted in three containers ---

Welcome to our community! 😃 > [@limedong1](#): > > because we now have one data directory mounted in three containers You can't do that, you need to have something like `/data/elasticsearch/data0`, `/data/elasticsearch/data1`, `/data/elasticsearch/data2`, ie specific directories for each node. ---

- I see what you mean,How do I set up a different data directory for each node in the cluster? ---

Each master and data node pod need a dedicated persistent volume. ---

I understand what you mean, but I am not sure how to add a private data directory for each container of ela cluster in k8s ---

That is a k8s question and not directly related to Elasticsearch, so I will leave that for someone else. ---
