[cinder-csi-plugin] Resize raw block device

Open sergelogvinov opened this issue 1 year ago • 6 comments

/kind bug

What happened:

During the volume expansion process, there is a risk of accidentally resizing an unmanaged (raw) block device if it already has a file system on it. Since raw block devices are not tied to any file system by Kubernetes, operations like resizing can potentially corrupt the existing file system, as it is unaware of the underlying changes.
