Recently I fell in love RedHat Linux, because his spirit GUN, so trying to learn, is to use a virtual machine installed, be afraid of the wood there are ways to control the character directly little strange but very attractive system, boot time is always displayed smartd process fails, so find technical articles, share with you.
In fact, there is a problem with my Linux no sound, the sound card is normal, but the test is not sound, the next goal is to solve this, huh, huh ~ ~
smartd is a daemon (a helper), it has a self-monitoring monitoring, analysis and reporting technology (Self-Monitoring,
Analysis, and Reporting Technology - SMART) hard disk.
SMART system makes hard to monitor and report on their health. It is an important feature is the ability to predict failure, so that the system administrator
To avoid data loss.
smartd by the kernel-utils packages installed by default. With the command rpm -ql kernel-utils kernel-utils package can list the files.
smartd daemon is normally open when the system starts, its configuration file is /etc/smartd.conf.
For example, suppose you have two hard drives are installed, / dev / hda and / dev / hdb. A device is CD_ROM, another hard disk. In order to detect them
Support SMART, use the command smartctl -i / dev / hda and smartctl -i / dev / hdb:
# / Usr / sbin / smartctl -i / dev / hda

/etc/smartctl.conf Can modify the file so that only monitors smartd you want to monitor equipment. Assuming only / dev / hda needs to be monitored,
On the device if there is a warning message occurs, you need to send it to the root user, then the need for such /etc/smartd.conf Review:
# /etc/smartd.conf
# Sample configuration file for smartd. See man 5 smartd.conf.

...
# A very silent check. Only report SMART health status if it fails
# But send an email in this case
/ Dev / hda -a -m
root@localhost.localdomain
...
Finished editing /etc/smartd.conf, restart the daemon:
# / Sbin / service smartd restart
Shutting down smartd: [FAILED]
Starting smartd: [OK]
To set smartd be activated at boot time, under the root user with chkconfig smartd on command.
Close smartd service starts automatically
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
Simply put, smartd is hard to monitor and predict the reliability of its failure, a daemon perform testing!
A closer look smartd instructions can! (Man smartd)
#chkconfig smartd off
This is close smartd service starts automatically when the machine is restarted smartd not run! |
