Mount–o REMOUNT,RW/

To mount a file system that has already been mounted (with read and write permission to mount), it is important to note that the mount point must be an existing directory, which may not be empty. The files that are commonly used in this directory are RO permissions and need to be temporarily changed to modifiable permissions.
