VMware Cloud Director Object Storage Extension 3.0 | 14 MAR 2024 | Build 23443325

Check for additions and updates to these release notes.

What's New

VMware Cloud Director Object Storage Extension version 3.0 includes the following new features:

  • VMware Cloud Director solution add-on installation

    Provider administrators now can install, upgrade or uninstall VMware Cloud Director Object Storage Extension by using the VMware Cloud Director Solutions Add-on UI. With the add-on installation, VMware Cloud Director Object Storage Extension runs as a container application in a Kubernetes environment. With the add-on installation, providers can deploy VMware Cloud Director Object Storage Extension either to a Tanzu Kubernetes Grid multi-cloud cluster in the Solutions organization or to a CNCF (Cloud Native Computing Foundation) compliant Kubernetes cluster outside of VMware Cloud Director. With the Tanzu Kubernetes Grid support, the add-on integrates with Tanzu standard packages for operation optimization, which includes Contour for service load balancing, Cert-manager for TLS certificate management, and Grafana for service metrics.

  • Day 2 deployment configuration through UI

    With the add-on installation, provider administrators can configure VMware Cloud Director Object Storage Extension on the VMware Cloud Director provider portal, which includes setting a replica number, importing or creating TLS certificate, connecting to a database, configuring storage platform, and so on.

  • VMware Cloud Director extension for Data Solutions integration

    With the add-on installation, provider administrators can select a VMware Postgres instance from the Solutions organization as the database of VMware Cloud Director Object Storage Extension.

  • Rolling updates

    With the add-on installation, configuration changes for VMware Cloud Director Object Storage Extension will be automatically verified and applied. Provider administrator can scale out / scale in VMware Cloud Director Object Storage Extension by using the the VMware Cloud Director provider portal.

  • Enhancement for S3

    Support to return ARN (Amazon Resource Name) for tenant storage users. Improved user experience for the Kubernetes cluster protection.

  • Enhancement for OSIS

    Enhanced interface of the Object Storage Interoperability Services to adapt storage vendors.

  • Refreshed support matrix

    Certified new versions of products in the support matrix, including VMware Cloud Director, VMware Cloud Director Container Service Extension, and storage platforms.

Localization

The new features and documentation of VMware Cloud Director Object Storage Extension 3.0 are available only in English.

Upgrade

You can upgrade directly to VMware Cloud Director Object Storage Extension 3.0 from versions 2.X. See Upgrading VMware Cloud Director Object Storage Extension.

From VMware Cloud Director Object Storage Extension 2.2.3, the CentOS 7 operating system is no longer supported. Verify that your operating system is supported before installing or upgrading to VMware Cloud Director Object Storage Extension 3.0.

If you plan to install VMware Cloud Director Object Storage Extension on a new operating system, you can migrate your existing configuration by using the ose config export and ose config import commands.

Caveats and Limitations

  • When you access a tenant organization as a cloud provider, you can see only local resources

    When you access a tenant organization, you can see only the local resources of this organizaiton. When you open the VMware Cloud Director Object Storage Extension Dashboard or Buckets page, you can see and select only the local organizations.

  • S3 API requests authenticated with application credentials do not support the following use cases:

    • Accessing a shared bucket if another user grants you permissions for the bucket.

    • Deleting multiple objects simultaneously with a single API request.

    • Copying objects from buckets that you own.

  • If you are using ECS storage, you cannot remove object tags.

    When you try to remove an object tag, the operation fails with an error.

  • VMware Cloud Director and the underlying storage systems have different limitations on user names. To use VMware Cloud Director Object Storage Extension, user names must comply with both the requirements of VMware Cloud Director and the underlying storage system. A best practice is to use short user names (under 50 bytes) and to use alphanumeric characters.

    • If you are using Cloudian storage, the maximum length of user IDs is 255 bytes.

    • If you are using Dell ECS, the maximum length of user IDs is 64 bytes.

  • Bucket synchronization supports up to 10 million objects per a single synchronization job

    When the cloud provider enables bucket synchronization for a tenant in the provider portal, the synchronization can support up to 10 million objects for the tenant. VMware Cloud Director Object Storage Extension does not support the synchronization for more than 10 million objects per a single bucket synchronization job.

  • If you are using ECS storage, S3 API, or the Find a Bucket feature, you cannot visit a bucket that belongs to a different tenant organization in the ECS platform.

Product Documentation

All documentation is available on the VMware Cloud Director Object Storage Extension Documentation page.

Known Issues

  • Deleting an object from an existing bucket after upgrading to VMware Cloud Director Object Storage Extension version 3.0, fails with an error

    If you upgrade to VMware Cloud Director Object Storage Extension version 3.0, then try to delete an object from an existing bucket, the process fails with the following error:

    Failed to exchange user info between Cloud Director and storage platform.

    The issue is observed if the tenant user who attempts the operation has a user name that contains special characters.

    Workaround:

    1. Navigate to the Postgres Database that VMware Cloud Director Object Storage Extension uses.

    2. In the table bucket_info, in the storage_user_id for buckets column, add the encoded tenant user name.

      You can find the encoded user name in the table platform_user_mapping, when you select the platform_user_id corresponding to user_name.

  • VMware Cloud Director authentication fails after you switch to remote region

    If you are in a multisite, multi-region environment and you switch to a remote region in a remote organization with a different name, the VMware Cloud Director authentication fails.

    Workaround: None.

  • Backing up an entire cluster fails

    When you try to back up a Kubernetes cluster, where a pod contains persistent volumes in the primary node, the process enters a partially failed status.

    Workaround: Activate Scheduling Pods in the Kubernetes Control plane primary nodes by running the following commands:

    kubectl taint nodes --all node-role.kubernetes.io/master-

    kubectl taint nodes --all node-role.kubernetes.io/control-plane-

  • The Kubernetes cluster protection status remains as Restoring

    After performing a restore task in the target Kubernetes cluster, the cluster protection status remains as Restoring. The problem might occur when VMware Cloud Director Object Storage Extension continues to monitor the status of the restoring task and the state of the task remains in an InProgress state.

    Workaround: Click the Refresh button on the cluster protection card.

  • The S3 service of VMware Cloud Object Storage Extension is unavailable

    When you start or view VMware Cloud Object Storage Extension, the VMware Cloud Object Storage Extension service is active, but the S3 service is unavailable, with the following error message in the log file:

    S3_TOKEN_AUTH_ERROR

    The issue is observed if the time gap between the S3 client and the VMware Cloud Object Storage Extension VM is over 20 seconds. 

    Workaround 1: Change the gap time between the S3 client and the VMware Cloud Object Storage Extension VM to less than 20 seconds, for example, NTP for the VMware Cloud Object Storage Extension VM.

    Workaround 2: Run the command oss.s3.request-expire-time=3600 and restart the VMware Cloud Object Storage Extension service.

  • Region metrics on the provider portal's tenant onboarding page does not distinguish region specific metrics data

    With multi-region deployment, when multiple regions are activated for a tenant organization, active region cards show the global consumption metrics, not region-specific data. The problem is observed, because region specific metrics is not supported yet.

    Workaround: None.
