Hi all!
I have a problem like described is this post.
My config:
mfsexports.cfg on Master:
192.168.206.0/24 / rw,alldirs,ignoregid,maproot=0
On client:
mfsmount /moosefs_mnt -H 192.168.206.1 -o mfscachefiles,suid
mkdir /moosefs_mnt/test
chmod g+s /moosefs_mnt/test
MFS Client is not used as MFS Master or Metalogger or Chunk server.
MFS Client is also a Win 2003 domain member Samba server
and directory /moosefs_mnt/test is shared by Samba.
chown "DOMAIN\some_group" /moosefs_mnt/test
ls -ld /moosefs_mnt/test
drwxrws--- 2 root some_group 0 2010..... /moosefs_mnt/test
Some domain-user is a member of "DOMAIN\some_group".
When he creates file or folder in /moosefs_mnt/test (via Samba share)
the newly created child folder does not inherit
groupID from its parent (as expected because the setgid flag is set):
ls -ld /moosefs_mnt/test/subdir
drwxrws--- 2 DOMAIN\domain-user NEWRIDAN\Domain users 0 2010..... /moosefs_mnt/test/subdir
As you can see newly created child folder has "Domain users"
group assigned. I think it is because "Domain users" is a primary group
for domain-user.
In the same time when test-folder is shared from EXT3 file system
setgid flag works perfectly.
Any idea? Thanks!

Oops, I missed the FAQ ... The entry says that MFS will test privileges only of main groups because it is much safer. I love "safer" so I would use the permission 755 instead of 750
Thanks Michał for you helps,
