Chapter 6. Creating Access to Volumes

Red Hat Gluster Storage requires certain ports to be open. You must ensure that the firewall settings allow access to the ports listed at Chapter 3, Considerations for Red Hat Gluster Storage.

Gluster user is created as a part of gluster installation. The purpose of gluster user is to provide privileged access to libgfapi based application (for example, nfs-ganesha and glusterfs-coreutils ). For a normal user of an application, write access to statedump directory is restricted. As a result, attempting to write a state dump to this directory fails. Privileged access is needed by these applications in order to be able to write to the statedump directory. In order to write to this location, the user that runs the application should ensure that the application is added to the gluster user group. After the application is added, restart gluster processes to apply the new group.
