If you look at: http://docs.redhat.com/docs/en-US/Red_Hat_Storage/2/html/User_Guide/chap-User_Guide-Geo_Rep-Preparation-Settingup_Environment.html It mentions /etc/glusterd/*. I believe this was changed to /var/lib/glusterd in RHS 2.0, so these paths are now invalid.
The updated documentation is available at: http://documentation-stage.bne.redhat.com/docs/en-US/Red_Hat_Storage/2/html/User_Guide/chap-User_Guide-Geo_Rep-Preparation-Settingup_Environment.html.
Verified it in the above mentioned link and the changes have been made.
