适用于

  • Trident 适用于 Kubernetes/Openshift
  • (群集) ONTAP MetroCluster 切换/回切
  • SVM-DR 使用故障切换/回馈

说明

根据在线文档,当使用 VServer-DR 的 MetroCluster 正在使用时,如果发生切换或回切,需要处理以下几件事:
  • 如果 SVM 名称在 TBC YAML 或 tridentctl 托管的 JSON 中(第 6 点:SnapMirror SVM 灾难恢复工作流程 for Trident),则需要更新 - 另请参阅 Issue #228
  • 从 TBC 创建的 TBE 在其定义中还保留了一个 storagePools 列表,尽管是 base64 编码的 - 请参阅:
    • kubctl get tbe <BACKEND> -n <TRIDENT_NAMESPACE> -o json
    • base64 -d "<base64_encoded_string>"
