To answer my one question and maybe it is helpful for the community:
Due to a different (minor) issue with the posix-permissions, we
set stat-prefetch to off.
This causes the issue mentioned below, i.e. it had nothing to do with the smb.conf setting.
gluster volume set volname performance.stat-prefetch on
solved that issue.

Dear Gluster-Users,
short story:
Two volumes are exported via smb/cifs with the
(almost) the same configuration with respect to smb.conf. The replicated volume
is easily accessible via cifs and fuse. The dispersed volume is accessible via fuse,
but not via cifs.
Error message from windows client:
The parameter is incorrect
Maybe the error is somehow related to this:

more information:
We have created a gluster setup that consists of three servers, and each server
provides two bricks. Two volumes are created on these bricks and are going to exported via
smb/cifs.
- replicated distributed
- dispersed
The volume settings are given here:

The export via cifs looks:
