FC plugin: Update detach logic for block volume if devicePath is empty **What this PR does / why we need it**: Currently, FC plugin doesn't have a chance to update attached volume's devicePath into volume object. Therefore, at the volume teardown path, FC plugin gets empty devicePath from kubelet then fails volume detach operations especially volumeMode is Block. This PR adds logic to obtain devicePath from global map path if passed devicePath from kubelet is empty. I think this PR isn't complete solution but is a workaround to avoid teardown failures. In order to solve the root cause, we need to discuss the way to update devicePath at kubelet side again.(https://github.com/kubernetes/kubernetes/pull/54264) If volume is managed by multipath, FC plugin fails to detach volume from kubelet node on both Filesystem and Block cases. This PR also fix the problem. **Which issue(s) this PR fixes** : Fixes #57153 **Special notes for your reviewer**: @rootfs @jsafrane **Release note**: ``` NONE ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
