I had sent you the full smb.conf, so no need to run testparm -s
--section-name global, please reference:

Yes, vfsgluster is a directory at the root of the export volume. It is
also currently mounted in /export so that the rest of the files can be
exported via samba with fuse mounts:

# mount | grep export
10.0.1.7:/export on /export type fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,allow_other,max_read=131072)

# ls -ld /export/vfsgluster

There are a total of 3 gluster peers, but only two have bricks. The
other is just present, but not even configured as an arbiter. Two of
the nodes with bricks run ctdb and samba.

I do not currently have the log file directive enabled in smb.conf, I
would have to enable it. Do you need me to repeat the process with it?
