场景

当磁盘报错的时候使用该命令排查

bash 复制代码 
fdisk -l /dev/sdb
fdisk: cannot open /dev/sdb: Input/output error

进一步使用 smartctl 排查

bash 复制代码 
smartctl -a /dev/sdb
输出
smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.4.0-144-generic] (local build)

解释下输出

smartctl -a /dev/sdb 命令的输出提供了关于 /dev/sdb 磁盘的详细信息。以下是各个部分的中文解释：

开始信息部分：

Vendor（厂商）:

AVAGO：这款磁盘由 AVAGO（现已并入 Broadcom）生产，说明它可能是与 RAID 控制器（如 MegaRAID）相关的磁盘。

Product（产品）:

MR9364-8i：这是 Broadcom/LSI MegaRAID SAS 9364-8i 控制器的产品名称，说明磁盘是通过这个 RAID 控制器管理的。

Revision（版本）:

4.28：磁盘固件的版本号。

Compliance（符合标准）:

SPC-3：磁盘符合 SPC-3 标准，这是存储设备的一种行业标准。

User Capacity（用户容量）:

12,000,675,495,936 bytes [12.0 TB]：磁盘的总容量为 12.0 TB。

Logical block size（逻辑块大小）:

512 bytes：磁盘的逻辑块大小为 512 字节。

Logical Unit id（逻辑单元 ID）:

0x600605b00b66a0802e83c37139e64fd4：这是该磁盘在 RAID 中的唯一标识符。

Serial number（序列号）:

00d44fe63971c3832e80a0660bb00506：这是磁盘的唯一序列号。

Device type（设备类型）:

disk：设备类型为磁盘。

Local Time is:

显示本地时间为：Fri Dec 20 15:57:50 2024 CST。

设备状态：

device is NOT READY：

这表明磁盘当前不可用。原因可能是磁盘已被关闭（spun down），或者磁盘正忙于其他操作（例如 RAID 重建、初始化等）。

如果磁盘处于忙碌状态或未准备好，则无法读取其 SMART 信息。

错误消息：

A mandatory SMART command failed：

这表示智能监控工具（SMART）在尝试获取磁盘状态时失败，通常是由于磁盘未就绪（NOT READY）。

提示信息中建议使用 -T permissive 选项继续命令，但这通常不推荐，因为它可能掩盖硬件问题。

总结：

从输出可以看出，磁盘 /dev/sdb 由于某些原因（如磁盘处于忙碌或未准备好状态）无法获取 SMART 信息。您可以检查磁盘是否在忙碌状态（如重建 RAID 阵列等），或者等待磁盘进入就绪状态后再尝试获取 SMART 信息。

下载 storcli工具

登录Broadcom官网


安装 storcli

bash 复制代码 
unzip MR_SAS_StorCLI_1-16-06.zip
unzip storcli_all_os.zip
cd storcli_all_os/Ubuntu/
sudo dpkg -i storcli_1.0_all.deb
sudo /opt/MegaRAID/storcli/storcli64 adpcount

storcli64 /c0/eall/sall show

/opt/MegaRAID/storcli/storcli64 /c0/eall/sall show 详细解释下这条命令

/opt/MegaRAID/storcli/storcli64 /c0/eall/sall show 是一条用于查看硬件 RAID 控制器配置的命令，具体含义如下：

命令组成

/opt/MegaRAID/storcli/storcli64：这是 storcli 工具的路径。storcli 是用于管理和查看 LSI（现为 Broadcom）MegaRAID 控制器的命令行工具。storcli64 是该工具的 64 位版本，通常用于管理和查看 RAID 配置、硬件状态、磁盘状态等。

/c0：指定控制器的编号。MegaRAID 控制器通常有多个，在这种情况下，/c0 指的是第一个控制器。如果有多个控制器，c0 表示第一个控制器，c1 表示第二个控制器，以此类推。

/eall：表示"所有外部设备"（enclosure）。在 MegaRAID 控制器中，磁盘阵列通常连接到外部机架（enclosure），使用 /eall 可以查看所有外部机架上的设备信息。

/sall：表示"所有槽位"（slot）。这意味着查看控制器上所有物理磁盘（所有槽位上的磁盘）的状态。

show：这是命令的操作部分，表示显示设备信息或状态。

命令作用

这条命令会显示有关 MegaRAID 控制器、所有连接的外部机架和所有槽位中的磁盘的详细信息。这包括控制器的状态、磁盘组配置、各个磁盘的健康状态、RAID 阵列的配置等信息。

输出内容解释

执行该命令后，通常会返回类似以下的信息：

控制器信息：

产品名称、固件版本、BIOS 版本、驱动程序版本等信息。

例如：

bash 复制代码 
Controller = 0
Product Name = AVAGO MegaRAID SAS 9364-8i
Firmware Version = 4.280.00-4410
Driver Version = 07.713.01.00-rc1
磁盘组信息（Disk Groups）：

显示当前 RAID 阵列的配置，包括阵列的类型（RAID1、RAID5 等）、大小、状态、缓存策略等。

例如：

bash 复制代码 
DG/VD TYPE  State    Size   Name
0/0   RAID5  Optimal  10.914 TB
物理磁盘信息（Physical Drives）：

显示控制器连接的每个物理磁盘的状态、型号、接口类型、大小等信息。

例如：

bash 复制代码 
EID:Slt DID State DG     Size   Model
252:0     6 Offln  0 3.637 TB ST4000NM000B-2TF100
252:1     5 Onln  0 3.637 TB ST4000NM000B-2TF100
磁盘状态：

显示每个磁盘的健康状态，状态包括 "Online"（在线）、"Offline"（离线）、"Degraded"（降级）等。

如果某些磁盘离线或出现故障，命令输出中会明确显示。

RAID 阵列的拓扑结构：

显示 RAID 阵列中各个磁盘的具体位置和状态。

例如：

bash 复制代码 
DG Arr Row EID:Slot DID Type State BT Size PDC PI SED DS3 FSpace
0 - - - RAID5 OfLn N 10.914 TB dflt N N none N
0 0 - - - RAID5 Dgrd N 10.914 TB dflt N N none N
RAID 磁盘组详细信息：

可能会显示阵列成员磁盘的更多详细信息，包括阵列类型、保护级别、缓存设置等。

总结

/opt/MegaRAID/storcli/storcli64 /c0/eall/sall show 主要是用于获取 MegaRAID 控制器中所有连接的磁盘、阵列以及相关硬件的详细信息。可以用来检查 RAID 阵列的健康状态、硬件配置、磁盘状态等。如果你需要了解磁盘的详细状态，特别是 RAID 阵列的配置、磁盘是否健康，这条命令是非常有用的。

根据输出信息，以下是关于 /dev/sdb 和其他驱动器的详细解释：

Drive Information 部分：

EID:Slt: 这表示 Enclosure Device ID（机架设备 ID）和 Slot Number（插槽编号）。

DID: 这是设备 ID，表示该磁盘的唯一标识符。

State: 这是磁盘的状态，包括：

Offln: 磁盘处于 离线 状态，不能被 RAID 控制器或系统访问。

UBad: 表示该磁盘是 未配置的坏磁盘，通常表示磁盘出现故障或损坏。

JBOD: 代表磁盘是 简单磁盘（Just a Bunch Of Disks），没有加入 RAID 阵列。

DG: Disk Group，磁盘所属的磁盘组。数字 0 表示这些磁盘都属于同一个磁盘组（即 RAID 阵列中的同一组磁盘）。

Size: 每个磁盘的容量，3.637 TB。

Intf: 接口类型，这里为 SATA，表示这些磁盘是通过 SATA 接口连接的。

Med: 存储介质类型。HDD 表示是机械硬盘（硬盘驱动器），SSD 表示是固态硬盘（固态驱动器）。

SED: 是否为自加密硬盘（Self Encrypting Drive）。N 表示不是自加密硬盘。

PI: 是否启用保护信息（Protection Information）。N 表示没有启用。

SeSz: 每个扇区的大小，通常为 512B。

Model: 磁盘的型号：

ST4000NM000B-2TF100：这是 3.637 TB 容量的 Seagate SATA 硬盘。

Samsung SSD 870 QVO 4TB：这是 4TB 容量的三星 SSD 固态硬盘。

Sp: 设备状态标志，U 表示设备是 启用（Up） 状态。

详细分析：

磁盘 252:0, 252:1, 252:2: 这些是 SATA HDD 硬盘，并且它们的状态是 Offln（离线）。这意味着它们未能正常连接或未被 RAID 控制器识别。

磁盘 252:3: 这个磁盘的状态是 UBad（未配置的坏磁盘）。这表示该磁盘存在严重故障，可能是硬件损坏，无法重新加入 RAID 阵列。

磁盘 252:4: 这是 SATA SSD 磁盘，状态是 JBOD（简单磁盘）。这表示该 SSD 尚未加入 RAID 阵列，它作为独立磁盘存在。

结论：

目前，三个 SATA HDD 磁盘处于离线状态，不能参与 RAID 阵列操作。

另一个 SATA HDD 磁盘的状态为坏磁盘，无法使用。

SATA SSD 磁盘尚未加入 RAID 阵列，作为单独的磁盘（JBOD）存在。

这些磁盘的离线或故障状态可能会导致 RAID 阵列无法正常工作。如果该阵列依赖于这些磁盘，它将处于降级或无法恢复的状态。您需要检查这些离线或坏磁盘的硬件连接、状态和是否需要替换。
