问题描述

使用system node migrate-root 命令迁移节点的根卷失败，并在 MGWD 日志中显示类似错误：

[kern_mgwd:info:2709]: INFO: NDO::MigrateRoot: Node is online after the reboot.

[kern_mgwd:info:2709]: INFO: NDO::MigrateRoot: Checking to see if the new root by name new_root is created.

[kern_mgwd:info:2709]: INFO: NDO::MigrateRoot: Checking the status of new_root. Command: /sbin/ngsh -c node run -node node-02 -command aggr status new_root . Retry count = 1

[kern_mgwd:info:2709]: ERR: NDO::MigrateRoot: Failed to get the status of new root aggregate. Error: 0 - :.

已成功创建new_root 聚合和卷、但原始根聚合和卷仍存在、无法恢复迁移作业。
