What is Smartmontools?
Smartmontools is a set of applications that can test hard drives and read their hardware SMART statistics. This how to will help you to configure Smartmontools to do actions such as shut down the computer or send an e-mail when the disk is going to fail.
What does long SMART test do?
All modern hard drives offer the possibility to monitor its current state via SMART attributes. These values provide information about various parameters of the hard disk and can provide information on the disk’s remaining lifespan or on any possible errors.
How long does a SMART self test take?
Checks the list of pending sectors that may have read errors, and it usually takes under two minutes. A longer and more thorough version of the short self-test, scanning the entire disk surface with no time limit. This test usually takes several hours, depending on the read/write speed of the drive and its size.
How long does a long drive self test take?
Long Drive Self Test: may take up to 4 hours, progress in 10% increments.
What is SMART FreeNAS?
SMART tests are internal drive tests. SMART tests are non-destructive, but they run on a per-disk interval, so it only runs on one disk at a time. S.M.A.R.T tests are essential for keeping track of your disk health. You also don’t want to schedule short and long tests at the same time. Check out my FreeNAS build!
What’s the maximum run time for a smart test?
Therefore, a maximum run time for the short test is 2 min. The test checks the disk by dividing it into three different segments. The following areas are tested: Electrical Properties: The controller tests its own electronics, and since this is specific to each manufacturer, it cannot be explained exactly what is being tested.
What does Smartmontools do for a hard drive?
Smartmontools is a set of applications that can test hard drives and read their hardware SMART statistics. Note: SMART data may not accurately predict future drive failure, however abnormal error rates may be an indication of possible hardware failure or data inconsistency.
What can be tested with a smart controller?
The following areas are tested: Electrical Properties: The controller tests its own electronics, and since this is specific to each manufacturer, it cannot be explained exactly what is being tested. It is conceivable, for example, to test the internal RAM, the read/write circuits or the head electronics.
What do I need to install Smartmontools on Linux?
S.M.A.R.T. is a system in modern hard drives designed to report conditions that may indicate impending failure. smartmontools is a free software package that can monitor S.M.A.R.T. attributes and run hard drive self-tests. Although smartmontools runs on a number of platforms, I will only cover installing and configuring it on Linux.
