hey all 
which type of persisstent storage I should use 4 my on-Premise cluster?
The problem is when I drain a node to update this one or the node failed all services will be offline if the persisent storage on this node?!
Is there a good solution 4 this? I think about NFS outside the cluster, but now I read that NFS is just for not intensive write operations?
Cluster information:
Cloud being used: Bare-Metal
Installation method: Kubeadm
Host OS: Linux-Buster
