I currently have a multi-node Kubernetes cluster running Wazuh.  A persistent volume was created using NFS.  I've read that using NFS is not an efficient way to run Elasticsearch.  My goal is to have 3 clustered Elasticsearch nodes and 3 clustered worker nodes in this setup.  I am running this on top of VMware VMs.  What are some good shared storage options?  Cloud services are not an option.For testing purposes right now, I may only be able to use 1TB-2TB of disk space.  Would GlusterFS or CephFS be a good option?  I do use Pure storage and I've read about Portworx volumes.  But that product is not available to me.I've wondered if it would be a good idea to build this on bare metal using K3OS as a single node Kubernetes cluster.  Kazuh would not be the primary monitoring/logging solution.
