Currently kubelet volume management works on the concept of desired and actual world of states. The volume manager periodically compares the two worlds and perform volume mount/unmount and/or attach/detach operations. When kubelet restarts, the cache of those two worlds are gone. Although desired world can be recovered through apiserver, actual world can not be recovered which may cause some volumes cannot be cleaned up if their information is deleted by apiserver. This change adds the reconstruction of the actual world by reading the pod directories from disk. The reconstructed volume information is added to both desired world and actual world if it cannot be found in either world. The rest logic would be as same as before, desired world populator may clean up the volume entry if it is no longer in apiserver, and then volume manager should invoke unmount to clean it up.
