Creating Links to Object Storage

Create a link from a File Storage with Lustre file system to an Object Storage bucket.

Use a link to import objects from Object Storage or export files from a Lustre file system to Object Storage.

Using the Console

  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 details page, under Resources, select Object Storage links.
    All Object Storage links in the file system are displayed in a table.
  3. Select Add.
  4. In the Add Object Storage link panel, enter or select the following values:
    1. Link name: Enter a user-friendly name for the link. Avoid entering confidential information.
    2. Compartment: Accept the default compartment or select the list to change compartments.
    3. Lustre directory: Enter the Lustre directory for this link. Files in this directory sync with Object Storage when a job runs.
      For example, /mnt/lustre
    4. Object Storage bucket in <compartment>: The specific bucket in the compartment you selected.
      For example, prod_EMEA.
    5. Object Storage bucket path or prefix: The specific path (or sub path) in the bucket you selected where the data is or needs to be. Files in this bucket sync with File Storage with Lustre when a job runs.
      For example, you might want to use the /sample/abc path in the bucket.
      Notice that Full Object Storage bucket path, a read-only field, is populated with what you enter in the previous two fields. For example, you might see <namespace>:/prod_EMEA/sample/abc, with <namespace> replaced by the actual namespace of the bucket you selected earlier.
    6. Select how to handle files with the same name or path during import or export. You can select from:
      • Skip (default). If the target already has the file, the job leaves it as-is and transfers only files that don't exist at the target. No files are overwritten. We recommend selecting this option to avoid accidental overwrites.
      • Overwrite: If the target already has the file, the job replaces it with the file from the source (from Lustre when exporting, from Object Storage when importing). Use this with caution. Select this option only if you intentionally want to refresh files. Ideally, take backups before you select Overwrite.
      • Tags: (Optional) Add one or more tags. If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, skip this option or ask an administrator. You can apply tags later.
  5. If you see a warning that the Lustre directory or Object Storage path or prefix overlaps with another link, either change one of the paths to remove the overlap (we recommend this option) or select the confirmation box to proceed, acknowledging the risk.
  6. Select Add.
  7. Repeat as necessary.
