例如,在较新版本的 PowerProtect Data Manager 19.18 或 19.19 中,不会创建装载日志,并且可以在还原作业上观察到以下故障。

Cause

还原失败与 PowerProtect DD (DD) 上启用的 NFS 配置有关。ESXi 主机无法装载 NFSv4 导出。在撰写本文时,ESXi 主机只能装载 NFSv3 或 NFSv4.1 导出。

 

场景一:

DD 启用了 NFSv3 和 NFSv4 版本,NFSv4 在 DD 上设置为默认值。

已启用 DD NFS 版本1

DD 命令显示默认服务器。

nfs option show

nfs 选项 show output

 

场景二:

DD 仅启用了 NFSv4。

已启用 DD NFS 版本2 


 

Resolution

根据当前的 DD NFS 配置,启用 NFSv3 并确保 DD 到 NFSv3 上的默认 NFS 导出版本:
 

  1. 通过 SSH 连接到 DD。
  2. 确认您当前的 NFS 配置。
nfs option show

NFSv3 已启用但 NFS 默认服务器为 NFSv4 的示例。

NSFV4 默认值

  1. 如果禁用,则启用 NFSv3。
nfs disable version 3
    1. 如果 NFS 是版本 4,则设置为 NFSv3。
nfs option set default-server-version 3
  1. 再次执行即时访问或文件级还原。
