I want do some device initiation by using Daemonset(K8s resource).

Actually the deivce has been formated(inside container) and mounted(inside container) successfully to a container path `/hostmnt/lvpmem/` which is mapped of `/mnt/` which is a host path.

`mountpoint` works fine in container

```
[root@driver-hm4ll /]
#mountpoint /hostmnt/lvpmem/
/hostmnt/lvpmem/ is a mountpoint

```

but `mountpoint` works wrong in host env

```
[root@host ~]# mountpoint  /mnt/lvpmem/
/mnt/lvpmem/ is not a mountpoint

```

Also the data I write in container under `/hostmnt/lvpmem/` can't been seen under `/mnt/lvpmem/` in host env.

How can I mount the device so that both host and container can see it ?  

Also, if container is destroyed does the mount relation also be destroyed ? I have no idea about umounting the device in host env if mount relation can't be seen.  

Some opensource project use `nsenter` in container to run such format/mount command does it help ?
