ZFS 故障检修指南(二）

 

• 看磁盘替换实例来从一个故障磁盘恢复系统。

• 用“zpool status -v”指令来识别潜在的数据破损。如果一个文件被破损了，你可以选择直接处理它，而不必恢复整个pool。

# zpool status -v rpool
  pool: rpool
 state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption. Applications may be affected.

action: Restore the file in question if possible. Otherwise restore the
        entire pool from backup.
