You shouldn't access or modify the backend filesystems manually, you can
accidentally create unexpected problems if you don't fully understand what
you are doing.

That said, most probably the access to the file is still working because
Gluster is using its cached information to locate the file. If the client
mount is restarted, probably the file won't be accessible anymore unless
you disable the "lookup-optimize" option (and this should recreate the link
file).

Xavi
