You need to use GFS or similar "cluster" file system - other file systems cache things internally, and therefore you will get this sort of problem.

For example, if you do an ls on each machine, they will cache the blocks that represent that directory - then you won't see any changes as long as that buffer is still available - hence the need to unmount or remount.  There is no way (that I know of) of using a "standard" filesystem locally mounted to both - the entire reason for the existence of GFS is this issue.
