Updating File System Root Squash Configuration

Update the root squash settings for a File Storage with Lustre file system.

    1. On the Lustre file systems list page, select the file system that you want to work with. If you need help finding the list page, see Listing File Systems.
    2. On the file system's details page, from the More actions menu, select Edit root squash.
    3. In the Edit root squash panel, provide the following values:
      • Squash: Select None or Root. The default value is None, so no remapping is done by default.
      • Squash UID: If Squash is set to Root, the root user (UID 0) is remapped to this value. The default value is 65534.
      • Squash GID: If Squash is set to Root, the root group user (GID 0) is remapped to this value. The default value is 65534.
    4. If you're squashing the root user, you can provide Root squash exceptions to exclude specific clients from the squash configuration. Enter the Client address that you want to exclude as a valid IP address or range. For example, 10.0.2.4 or 10.0.[2-10].[1-255]. Select + Another client address to add up to 10 exceptions.
    5. Select Update.

  • Use the oci lfs lustre-file-system update command and the --root-squash-configuration parameter to update a file system's squash configuration:

    oci lfs lustre-file-system update --root-squash-configuration <root_squash_config_JSON>

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the UpdateLustreFileSystem operation with the rootSquashConfiguration attribute to update a file system's squash configuration.
