RedHat Linux启动时出现linux smartd 【FAILED】的解决方法

ykmail 2016-01-19

最近爱上RedHat Linux,因为他的GUN精神,于是在努力学习,是用虚拟机装的,怕木有办法直接驾驭这个性格有点怪但是很有魅力的系统,开机时总是显示smartd进程失败,于是找到相关技术文章,分享下。

其实还有个问题,我的Linux没有声音,声卡是正常的,但测试声音就是没有,下一个目标就是解决这个,呵呵~~

smartd是一个守护进程(一个帮助程序),它能监视拥有自我监视,分析和汇报技术(Self-Monitoring,
Analysis, and Reporting Technology - SMART)的硬盘。
SMART系统使得硬盘能监视并汇报自己的运行状况。它的一个重要特性是能够预测失败,使得系统管理员
能避免数据丢失。
smartd由kernel-utils包缺省安装。用命令 rpm -ql kernel-utils 可以列出kernel-utils包中的文件。
smartd守护进程通常在系统启动的时候被开启,它的配置文件是/etc/smartd.conf。
比如,假设有两个硬盘被安装,/dev/hda和/dev/hdb。一个是CD_ROM设备,另一个是硬盘。为了检测它们
是否支持SMART,使用命令 smartctl -i /dev/hda 和 smartctl -i /dev/hdb:
# /usr/sbin/smartctl -i /dev/hda

SMART support is: Enabled
”SMART support is: Available - device has SMART capability.“这行说明支持SMART。"SMART
support is: Enabled”这行说明SMART已经被打开。
CD-ROM设备和旧式的硬盘不支持SMART,这可以从smartctl -i /dev/hdb的输出看出:
# /usr/sbin/smartctl -i /dev/hdb

SMART is only available in ATA Version 3 Revision 3 or greater.
We will try to proceed in spite of this.
SMART support is: Unavailable - device lacks SMART capability.
A mandatory SMART command has failed: exiting. To continue, use the -T
option to set the tolerance level to 'permissive'
注意有些硬盘控制器不支持SMART。比如有些硬件RAID控制器不支持,或者不会传递SMART信息,即使加入
的硬盘支持SMART。
可以修改/etc/smartctl.conf文件,使得smartd只监视你想监视的设备。假设只有/dev/hda需要被监视,
在该设备上如果有警告信息发生,需要把它发给根用户,那么/etc/smartd.conf需要这样修改:

# /etc/smartd.conf
# Sample configuration file for smartd.  See man 5 smartd.conf.
# Home page is:
http://smartmontools.sourceforge.net
...
# A very silent check.  Only report SMART health status if it fails
# But send an email in this case
/dev/hda -a -m
[email protected]
...
编辑完/etc/smartd.conf,重启该守护进程:

# /sbin/service smartd restart
Shutting down smartd:                                      [FAILED]
Starting smartd:                                        [  OK  ]
要设置smartd在系统启动时候被激活,在根用户下用 chkconfig smartd on 命令。

关闭smartd服务自动启动
root LINUX smartd  is a daemon that monitors the Self-Monitoring, Analysis and Reporting
Technology (SMART) system built
  into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to
monitor the reliability
  of  the  hard  drive  and predict drive failures, and to carry out different types of
drive self-tests.  This
  version of smartd is compatible with ATA/ATAPI-7 and earlier standards
简单地说,smartd是监控硬盘的可靠性并预测其失败、进行测试的守护进程!
仔细看看smartd的说明即可!(man smartd)
#chkconfig smartd off
这是关闭smartd服务自动启动,机器重新启动时smartd不再运行!
