I think mount -a will only try to mount filesystems that are not already

 -a, --all
         Mount all filesystems (of the given types) mentioned in fstab.


         Attempt  to remount an already-mounted filesystem.  This is
         commonly used to change the mount flags for a filesystem,
         especially to make a readonly filesystem writeable.
