statvfs api couldn't fetch files and free details for mounted path

  I  tried to find the free space on mounted volume which is aws elastic filesystem. used statvfs api to find, but statvfs_obj.f_bavail and statvfs_obj.f_blocks are 13digit numbers, statvfs_obj.f_files and statvfs_obj.f_ffree are zeros.

  How to retrieve correct details from mounted aws efs on linux by using statvfs( mounted_filesys_path, &statvfs_struct_obj).  Th path looks like /mnt/efs_mounted_from_xx_city.

  OS: RHEL7.4,

  mount details:  nfs4, rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,noresvport,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=xxxx,local_lock=none,addr=xxxxx 0 0

This is supremely difficult. Far more difficult than it should be. provides a very compact discussion of the related problems + one potential way to... approach a fix...
I think, it's very difficult to find the source filesystem name from mounted path in generic(amazon, google, redhat, ... storages). So, ignored.
