磁盘出现故障,并出现存储错误 RAID 标签不匹配

[raid.label.io.writeError:error]: Label write on Disk 4a.2 Shelf 0 Bay 2 [Maxtor 5A250J0U66 RBTU]S/N [A40DPXAE] failed with storage error raid label does not match. The system will stop using the disk for I/O operations.

  • Data ONTAP 维护两个 RAID 标签副本:标签 1 和标签 2 。
  • 当 Data ONTAP 需要更新标签时(例如,在向 聚合添加磁盘 更改聚合状态时),它会将每个标签 1 写入 聚合中的参与磁盘,并将每个标签读回,如果结果 与 Data ONTAP 匹配,则会对标签 2 执行相同的操作。
  • 此错误表示存储层声称可以无 任何问题地读写到磁盘,但 ONTAP 读回的标签与 它写入的标签不匹配。然后,系统会建议磁盘出现故障。
  • 通常,这是一个写入丢失问题,但未检测到的坏扇区 也可能导致此问题。
