适用场景

  • ONTAP 9
  • 适用于Azure的Cloud Volumes ONTAP

问题描述

  • 使用System Manager升级双节点Azure CVO。
  • 升级节点后、由于集群未处于仲裁状态、升级将进入 paused-on-error 状态。
::*> cluster image show-update-progress Estimated Elapsed Update Phase Status Duration Duration -------------------- ----------------- --------------- --------------- Pre-update checks completed 00:10:00 00:03:04 ONTAP updates completed 01:32:00 00:49:24 Post-update checks paused-on-error 00:10:00 00:30:34 Details: Post-update Check Status Error-Action -------------------- ----------------- -------------------------------------- Cluster Quorum Error Error: Cluster is not in quorum. Status Action: Use the (privilege: advanced) "cluster ring show" command to verify all replication unit details. 7 entries were displayed.
  •  Cluster ring show (在diag模式下运行)显示CRS环未同步。可以看到CRS数据库从联机状态变为脱机状态,再到1个节点快速连续显示脱机状态:

示例:
