Goal

we try to solve when csi exit unexpect, the pod use cephfs pv can not auto recovery because lost mount relation until pod be killed and reschedule to other node. i think this is may be a problem. may be csi plugin can do more thing to remount the old path so when pod may be auto recovery when pod exit and restart, the old mount path can use.

NoGoal

Pod should exit and restart when csi plugin pod exit and mount point lost. if pod not exit will get error of **transport endpoint is not connected**.

implment logic

csi-plugin start:

	1. load all MountCachEntry  from node local dir
	2. check if volID exist in cluster, if no we ignore this entry, if yes continue
	3. check if stagingPath exist, if yes we mount the path
	4. check if all targetPath exist, if yes we binmount to staging path

NodeServer:

1. NodeStageVolume: add MountCachEntry on local dir include readonly attr and ceph secret
2. NodeStagePublishVolume: add pod bind mount path to MountCachEntry  and persist local dir
3. NodeStageunPublishVolume: remove pod bind mount path From MountCachEntry  and persist local dir
4. NodeStageunStageVolume: remove MountCachEntry  from local dir
