问题

在磁盘上看到中等错误，磁盘失败并发生重建

Sat Dec 17 11:31:22 -0800 [node01: disk_server_0: disk.ioMediumError:notice]: Medium error on disk 1a.10.5: op 0x2f:012cf400:0400 sector 19723448 SCSI:medium error - Unrecovered read error - If the disk is in a RAID group, the subsystem will attempt to reconstruct unreadable data (3 11 0 2d) (2730) Disk 1a.10.5 Shelf 10 Bay 5 [NETAPP X316_HAKPE06TA07 NA01] S/N [1234567] UID [5000CCA2:4D33CF14:00000000:00000000:00000000:00000000:00000000:00000000:00000000:00000000]

在此之后，同一 RAID 组中另外 2 个具有相似使用寿命的磁盘开始出现中等错误，最终也会出现故障
