Description Jan Safranek 2020-08-07 13:34:05 UTC

Description of problem:

NodeUnpublish call on already unmounted directory failed with NotFound

E0807 13:21:57.324110       1 utils.go:50] GRPC error: rpc error: code = NotFound desc = Volume not mounted

The call should be idempotent, therefore return success if the volume was already unmounted.

Version-Release number of selected component (if applicable):
The version in today's 4.5 OLM catalog

How reproducible:
Always

Steps to Reproduce:
1. Run a pod with a Manila NFS volume
2. ssh to a node and unmount the volume
3. Delete the pod

Actual results:
The pod is Terminating forever

Expected results:
The pod is deleted

Additional info:
Please check also other CSI calls too, esp. NodePublish on already mounted volume - it must be idempotent too.

This is related to https://bugzilla.redhat.com/show_bug.cgi?id=1862523. Not the root cause though.
