Symptoms
NetWorker 备份工作流执行不可用,并且不会继续将数据保存到 Data Domain 备份池。NetWorker Management Console (NMC) 警报显示一条消息,指示它正在等待目标备份池的卷:
Media Waiting event: Waiting for 1 writable volume(s) to backup pool <Pool_name> disk(s) or tape(s) on <Networker_server_name> for client(s) <storage_node_name> The NetWorker Server daemon.raw shows:
MM/DD/YYYY HH:MM:SS 2 5 170 7656 7652 0 <Networker_server_name> nsrd NSR warning Operation on device <device_name> failed: Setting file access times for '/Oracle/xxxx/volhdr'failed [5005] ([ 3600] [5600] Sat Mar 23 03:00:59 2019 ddp_utime() failed, Path //Oracle/xxxx/volhdr, Err: 5005-nfs setattr failed (nfs: No space left on device)).
Cause
The Data Domain ddboost 设备 volhdr 头文件无法访问,因此卷已在 NetWorker 存储节点上卸载。
而 volhdr 头文件包含 NetWorker 存储节点读取卷所需的元数据。
Resolution
- 打开 NetWorker Management Console (NMC),然后选择 Media 选项卡。
- 从介质选项卡中,选择左侧导航窗格中的磁盘卷。
- 在右侧详细信息窗格中,验证目标卷是否为”
appendable“而不是”空白”。屏幕截图示例:
- 检查是否装载了使用这些卷的设备。
- 使用卷卸载设备并将卷模式从“空白”更改为”
appendable”的限制。 - 装载正在使用卷的设备。
- 执行到目标备份池的备份。
