Detailed Description

DLD of configuration schema.

This file defines the interfaces and data structures to store and access the Motr configuration information in database. Motr configuration information is used to describe how a Motr file system is organized by storage, nodes, devices, containers, services, etc.

These data structures are used for on-disk purpose.

Overview

This DLD contains the data structures and routines to organize the configuration information of Motr, to access these information. These configuration information is stored in database, and is populated to clients and servers who are using these information to take the whole Motr system up. These information is cached on clients and servers. These information is treated as resources, which are protected by locks. So configuration may be invalidated and re-acquired (that is update) by users when resources are revoked.

The configuration schema is to provide a way to store, load, and update these informations. How to maintain the relations in-between these data strucctures is done by its upper layer.

Type of Motr service.

Note: After modifying this enum you should update ‘conf_service_types’ tuple in utils/m0confgen.; Append new values to the end and do not reorder existing values. This is to avoid changing service type values that are hard-coded in Motr conf strings.DTM0 service
