Change nfs path without reinstalling helm package #331

AlistairMcCutcheonIAS commented 4 months ago

I've been using this for some time, but I need to change the nfs path that I'm using. I have several persistent volumes which I don't want to delete. As per the readme, the way to install the helm package is:

helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
    --set nfs.server=x.x.x.x \
    --set nfs.path=/exported/path

But is there any way to change the nfs.path after it is installed please?

It is not possible to change the path in existing volumes.

Rename/move the data folder on the NFS server (if the archiveOnDelete policy is not set), then delete pv/pvc, then move the data back to its place after creation of new pv/pvc.

In the case of a database, temporary replace the command with ["/bin/sleep", "infinity"] to maintain data consistency.

Well, since https://github.com/kubernetes/kubernetes/issues/54562 configuration for NFS volumes is effectively set in stone, so there are no easy way to move data automatically.

Nevertheless, I removed the stale label, because this issue can be addressed, at least with mention of some workarounds in the docs.
