What is the default port of NFS server?
2049
The NFS Daemon runs only on NFS Servers (not on clients). It already runs on a static port, 2049 for both TCP and UDP. Firewalls should be configured to allow incoming packets to this port on both TCP and UDP.
What is NFS in OpenShift?
NFS implements the OpenShift Container Platform Recyclable plug-in interface. Automatic processes handle reclamation tasks based on policies set on each persistent volume. By default, PVs are set to Retain . Once claim to a PVC is deleted, and the PV is released, the PV object should not be reused.
What is NFS node?

What is NFS Kubernetes?
Network File System (NFS) is a standard protocol that lets you mount a storage device as a local drive. Kubernetes allows you to mount a Volume as a local drive on a container. The NFS integration is very useful for migrating legacy workloads to Kubernetes, because very often legacy code accesses data via NFS.
What are NFS volumes?
Kubernetes Volumes and NFS Kubernetes Volumes are abstracted storage units that allow nodes within a cluster to write, read and share data between them. Kubernetes offers many storage plugins that provide access to storage services and platforms.
How to request persistent storage from NFS server?

How to configure NFS based persistent volume in Kubernetes?
How to Configure NFS based Persistent Volume in Kubernetes 1 NFS Server IP = 192.168.1.40 2 NFS Share = /opt/k8s-pods/data 3 K8s Cluster = One master and two worker Nodes More
What is the IP of the NFS server?
NFS Server IP = 192.168.1.40 Note: Make sure NFS server is reachable from worker nodes and try to mount nfs share on each worker once for testing. Create a Index.html file inside the nfs share because we will be mounting this share in nginx pod later in article.
