Hi, Prabu! This behavior is expected because you are using non-clustered filesystem (ext4 or xfs or whatever), which is not expected to be mounted to multiple hosts at the same time. What's more - you can lose data when doing like this. That's the nature of local filesystems. So if you need to access filesystem simultaneously at two or more hosts - consider using clustered filesystem like CephFS, OCFS etc or using network mounts like NFS or Samba.
