PV detach from shutdown node

[lavalex]

Hello,

When node goes down, pod is deployed on another node, but NFS mount stays "attached" to the failed node. Is it expected to happen?

Thanks.

@lavalex Yes, it’s expected that NFS mounts stay attached when a node fails.

If a node goes down unexpectedly, Kubernetes does not immediately clean up or forcefully unmount the NFS volume.
The PV remains "attached" to the failed node until Kubernetes detects the failure.

One Approach that is common check persistentVolumeReclaimPolicy in pv.yaml and check it should be Retain i think this may fix it. As this approach is actively taken and work for majority of the people.
