11.2. Setting Multiple Volume Option A group configuration file is a file used to define and customize volume options. There are some predefined group configuration files for specific workload patterns like negative lookup cache, virtualization, metadata cache and gluster-block. The parameters defined in the file can then be applied to a volume as a group, rather than setting one parameter at a time.

Add the parameters and values that you want to set on the volume to the created file as key-value pairs, placing each parameter on a new line: For example, Adding configurations to volumes Run the following command to apply the configurations in the group file to specific volumes: For example, Note The configuration file created should be placed in all the hosts of the trusted storage pool under /var/lib/glusterd/groups/ . This can be achieved with the help of gdeploy configuration file. For information on deactivating group configuration, see Section 21.5, "Deactivating a group configuration"
