--- Comment #9 from joao.bauto at neuro.fchampalimaud.org ---
So I think I'm hitting this bug also.

I have an 8 brick distributed volume where Windows and Linux clients mount the
volume via samba and headless compute servers using gluster native fuse. With
parallel-readdir on, if a Windows client creates a new folder, the folder is
indeed created but invisible to the Windows client. Accessing the same samba
share in a Linux client, the folder is again visible and with normal behaviour.
The same folder is also visible when mounting via gluster native fuse.

The Windows client can list existing directories and rename them while, for
files, everything seems to be working fine.

Gluster servers: CentOS 7.5 with Gluster 5.3 and Samba 4.8.3-4.el7.0.1 from
@fasttrack

Clients tested: Windows 10, Ubuntu 18.10, CentOS 7.5
