We have a cluster with multiple elastic instances deployed on a few servers. We decided to use ECK to manage our cluster. We are looking for the best option for persistent volume for an ECK cluster.
We have tried NFS and Local Volumes. However, NFS volume is not recommended to be used with Elasticsearch (here and here). We also have problems using Local volume (Pod crashes after a few document insertion).
Could you please help us to choose best volume option for our case?
We use Debian on our servers.
