Creating a Parallel File System

You can create a parallel file system on the console.

Procedure

  2. Click Create Parallel File System in the upper right corner of the page. The page for creating a parallel file system is displayed.

  3. Select a region and enter a name for the parallel file system.

    • Once a parallel file system is created, its name cannot be changed. Plan a proper name in advance.
    • When a URL is used to access the parallel file system, the parallel file system name will become a part of the URL. According to DNS rules, URLs do not support uppercase letters and cannot distinguish names containing uppercase letters. Therefore, a parallel file system name can contain only lowercase letters, digits, periods (.), and hyphens (-). For example, if you attempt to access the parallel file system MyFileSystem using a URL, the file system name will be resolved to myfilesystem, causing an access error.

  4. Policy: You can select the Private, Public Read, or Public Read and Write policy for the parallel file system.
  5. Data Redundancy Policy: If you select multi-AZ storage, data is stored across multiple AZs.

    Once a parallel file system is created, you cannot change the data redundancy policy. Therefore, plan according to your service needs.

  6. Tags: Tags are used to identify parallel file systems in OBS, for the purpose of classification. Each tag is represented by one key-value pair. For details about how to add a tag, see Tags.
  7. Confirm the price at the bottom of the page and click Create Now.
  8. After the parallel file system is created, you can view it on the parallel file system list.

    Then, you can use the parallel file system the way as you using a bucket. For details about how to use PFS, see Using PFS.
