I have a 3 node cluster running on bare metal. it was setup using kubeadm. Each node in the cluster has 100GB disk space, total add up to 300GB.
I would like to utilize the 300GB disk space available on them to run stateful pods like mysql, postgresql, mongodb, cassandra etc. what are the different opensource options available to create persistent volumes.
I still havent used kuberentes v1.14 which offers local persistent volumes out of the box. It would be one of the option
second option is to run NFS server on each node and utilize the nfs share from the respective machine to create PV's.
Apart from these what other options can be looked at. please suggest
