I have added instructions on using Linux to mount over CIFS. The documentation of the same is available at: http://documentation-stage.bne.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/sect-Administration_Guide-GlusterFS_Client-CIFS.html#id2857734

The above mentioned url is not browseable, so I verified it from source and it looks fine.

Thanks! Two minor points I'd like to add for improving:

1. use the full filename for /etc/samba/smb.conf instead of smb.conf
2. instead of passing username+password in /etc/fstab, use the 'credentials=' 
   option as advised in 'man mount.cifs':

       credentials=filename
           specifies a file that contains a username and/or password. The
           format of the file is:

                         username=value
                         password=value
           This is preferred over having passwords in plaintext in a shared
           file, such as /etc/fstab. Be sure to protect any credentials file
           properly.

I have incorporated Niels suggestions. Updated guide is available at: http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/sect-Administration_Guide-GlusterFS_Client-CIFS.html#sect-Administration_Guide-GlusterFS_Client-CIFS-Automatic

Could you use a clearer example? I think it would be easier for users to understand if you have something like 'credentials=/etc/samba/mountpoint.passwd' instead of 'credentials=file1'.

As the format of the (in this example) /etc/samba/mountpoint.passwd is important, it would be good to have a reference to the manual page of 'mount.cifs' which explains the format.

Thanks again!

I have added path for the password file and reference to man page, updated documentation is available at http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/sect-Administration_Guide-GlusterFS_Client-CIFS.html#sect-Administration_Guide-GlusterFS_Client-CIFS-Automatic

Verified in the above mentioned link and it looks fine.
