The statement accurately describes the internal process of creating a file system on a Huawei OceanStor V3 unified storage system that utilizes the RAID 2.0+ architecture. In this environment, file services (NAS) are built upon the underlying block storage infrastructure. When an administrator creates a file system, the OceanStor system first automatically allocates a block-level volume, which is functionally a LUN, from the designated storage pool. This LUN is typically internal or private, meaning it is not directly exposed to hosts for block access. The system's file engine then formats this automatically-created LUN with its native file system (e.g., CloveFS), which is then made available over the network as a share (e.g., via CIFS or NFS). This layered approach is fundamental to the unified storage architecture.

This is a "TRUE OR FALSE" question. The provided statement is factually correct based on the system's architecture, so the "False" option is incorrect. A false statement would imply that file systems are created directly on the storage pool without an intermediary block-level LUN, which is not how the OceanStor V3 unified architecture is designed.

1. Huawei HCIA-Storage V4.5 (H13-611) Official Training Material. In the "File Storage Service and Technology" module

the logical architecture of file services is explained. It details that a file system is created within a storage pool. The process involves the system creating a LUN from the pool to serve as the container for the file system. This confirms that the file system is generated on an underlying LUN.

2. Huawei OceanStor V3 Series V300R006 Product Documentation; File Service Guide. In the section "Basic Concepts > File System"

the documentation states: "When you create a file system

you must specify the storage pool from which storage resources are allocated. The system automatically creates a LUN from the specified storage pool and then creates a file system on the LUN." This directly validates the process described in the question.

3. Huawei OceanStor RAID 2.0+ Smart Virtualization Technology White Paper. This document describes the architecture of RAID 2.0+

where a large storage pool is created from underlying disk resources. Both block services (LUNs) and file services (file systems) are provisioned from this common pool. The white paper's architectural diagrams illustrate that file services are a layer built on top of the virtualized block storage foundation

reinforcing the concept of a file system residing on an underlying block volume (LUN).
