Fedora 19 : S.M.A.R.T. - SMARTd - SMARTctL - SMARTmonTools - gSMARTcontroL




Monitoring Hard Disks with SMART

When a failure is anticipated by S.M.A.R.T., 
the user may choose to replace the drive to avoid unexpected outage and data loss.

Fedora comes with a "smartd" service that will email root if serious problems are detected on disks.

[root@server ~]# yum provides smartd
Loaded plugins: langpacks, refresh-packagekit
smartmontools-6.1-1.fc19.x86_64 : Tools for monitoring SMART capable hard disks
Repo        : fedora
Matched from:
Filename    : /usr/sbin/smartd

smartmontools comes with two programs:
   - smartctl : meant for interactive use
   - smartd   : continuously monitors S.M.A.R.T.


Check smartctl daemon service
   # service smartd status



[root@abxrds ~]# 
[root@abxrds ~]# service smartd status

To ensure that your drive supports SMART, type:
smartctl -i /dev/sda 

SMART will also give you a lot of detailed information about the drive : 
smartctl -a /dev/sda

[root@gate ~]# smartctl -a /dev/sda

Testing a Drive


You may run any type of test while the drive is mounted although there may be some drop in performance. There are three types of test that can be conducted on a drive:
  1. Short
  2. Extended (Long)
  3. Conveyance
To find an estimate of the time it takes to conduct each test, type:
sudo smartctl -c /dev/sda 

The most useful test is the extended test (long). You can initiate the test by typing:
sudo smartctl -t long /dev/sda 

Results


You can view a drive's test statistics by typing:
sudo smartctl -l selftest /dev/sda 

Suggested application: GSmartControl

[root@gate ~]# yum install gsmartcontrol
Loaded plugins: langpacks, refresh-packagekit
Package gsmartcontrol-0.8.7-2.fc19.x86_64 already installed and latest version
