**Smartctl**（S.M.A.R.T 自监控，分析和报告技术）是类Unix系统下实施SMART任务命令行套件或工具，它用于打印SMART**自检**和**错误日志**，启用并禁用SMRAT**自动检测**，以及初始化设备自检。


Smartctl对于Linux物理服务器十分有用，在这些服务器上，可以对智能磁盘进行错误检查，并将与**硬件RAID**相关的磁盘信息摘录下来。


在本帖中，我们将讨论smartctl命令的一些实用样例。如果你的Linux上海没有安装smartctl，请按以下步骤来安装。


![](/images/p/201501/16/162204x9qqklzo66kl8j88.png)


### 安装 Smartctl


**对于 Ubuntu**



```
$ sudo apt-get install smartmontools

```

**对于 CentOS & RHEL**



```
# yum install smartmontools

```

### 启动Smartctl服务


**对于 Ubuntu**



```
$ sudo /etc/init.d/smartmontools start

```

**对于 CentOS & RHEL**



```
# service smartd start ; chkconfig smartd on

```

### 样例


#### 样例：1 检查磁盘的 Smart 功能是否启用



```
root@linuxtechi:~# smartctl -i /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF INFORMATION SECTION ===
Model Family:     Seagate Momentus 5400.6
Device Model:     ST9320325AS
Serial Number:    5VD2V59T
LU WWN Device Id: 5 000c50 020a37ec4

SMART support is: Available - device has SMART capability.
SMART support is: Enabled

```

这里‘/dev/sdb’是你的硬盘。上面输出中的最后两行显示了SMART功能已启用。


#### 样例：2 启用磁盘的 Smart 功能



```
root@linuxtechi:~# smartctl -s on /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
SMART Enabled.

```

#### 样例：3 禁用磁盘的 Smart 功能



```
root@linuxtechi:~# smartctl -s off  /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
SMART Disabled. Use option -s with argument 'on' to enable it.

```

#### 样例：4 显示磁盘的详细 Smart 信息



```
root@linuxtechi:~# smartctl -a /dev/sdb              // For IDE drive
root@linuxtechi:~# smartctl -a -d ata /dev/sdb       // For SATA drive

```

#### 样例：5 显示磁盘总体健康状况



```
root@linuxtechi:~# smartctl -H  /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF READ SMART DATA SECTION ===

```

#### 样例：6 使用long和short选项测试硬盘


**Long测试**



```
root@linuxtechi:~# smartctl --test=long /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===
Sending command: "Execute SMART Extended self-test routine immediately in off-line mode".
Drive command "Execute SMART Extended self-test routine immediately in off-line mode" successful.
Testing has begun.
Please wait 102 minutes for test to complete.
Test will complete after Sun Nov 16 14:29:43 2014

Use smartctl -X to abort test.

```

或者，我们可以重定向测试输出到日志文件，就像下面这样



```
root@linuxtechi:~# smartctl --test=long /dev/sdb > /var/log/long.text

```

**Short测试**



```
root@linuxtechi:~# smartctl --test=short /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===
Sending command: "Execute SMART Short self-test routine immediately in off-line mode".
Drive command "Execute SMART Short self-test routine immediately in off-line mode" successful.
Testing has begun.
Please wait 1 minutes for test to complete.
Test will complete after Sun Nov 16 12:51:45 2014

Use smartctl -X to abort test.

```

或



```
root@linuxtechi:~# smartctl --test=short /dev/sdb > /var/log/short.text

```

**注意**：short测试将花费最多2分钟，而在long测试中没有时间限制，因为它会读取并验证磁盘的每个段。


#### 样例：7 查看驱动器的自检结果



```
root@linuxtechi:~# smartctl -l selftest /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF READ SMART DATA SECTION ===
SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Short offline       Completed: read failure       90%       492         210841222
# 2  Extended offline    Completed: read failure       90%       492         210841222

```

#### 样例：8 计算测试时间估值



```
root@linuxtechi:~# smartctl -c  /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)
