Description

our application using an RWX cephfs volume share files between POD in different NODE, and this application do `mount` operation in this volume subdirectory like `/share`,
the `mount` src is an hostpath file, after this operation, we can see the this file in the application NODE's kubelet volume directory `volumes/kubernetes.io~csi/pvc-f1f23430-de13-41ac-966d-4f972e22765e/mount`, but see nothing in other NODE! i have tested RWO local-path volume, ALL POD using this volume could see the `mount` operation effect, could you explain why cephfs volume is this behavior ?
