    Object Storage Service:FAQ about OSS-HDFS

    Last Updated:Dec 18, 2023

    This topic provides answers to some commonly asked questions about OSS-HDFS.

    What do I do if I accidentally delete a lifecycle rule configured for OSS-HDFS data after the automatic storage tiering feature is enabled?

    After the automatic storage tiering feature is enabled, OSS automatically configures a lifecycle rule to convert the storage class of data to IA, Archive, or Cold Archive. If you delete the lifecycle rule, the automatic storage tiering feature may not work as expected.

    Solution

    1. Disable the automatic storage tiering feature.

      1. Click Configure.

        lifecycle

      2. In the Basic Settings section of the Automatic Storage Tiering panel, turn off Status and click OK.

        setting

      3. In the message that appears, click OK.

    2. Reconfigure a lifecycle rule.

      1. On the OSS-HDFS tab, click Configure.

      2. In the Basic Settings section of the Automatic Storage Tiering panel, turn on Status.

      3. Click OK.

        OSS reconfigures a lifecycle rule to convert the storage class of data to IA, Archive, or Cold Archive.

    Can I convert the storage class of Archive or Cold Archive objects to Standard or IA?

    Yes. For example, if you want to convert an Archive object to a Standard object, set -policy to CLOUD_STD. For more information, see Automatic storage tiering of OSS-HDFS.
