#Ssd health linux install

Once we know which drive we are going to analyze to check its health through SMART, we must know that there are a total of two different tests that we can perform: Generally in Linux systems we will find the disks in the /dev/sdX path. We have to use this program at the hard disk or SSD level, not at the partition level. These commands will show us a list of the units and also of the partitions. For example, on Debian operating systems with apt it would be as follows: Installation of this program, if it is not installed by default on your Linux distribution, is by using your distribution’s package manager. Of course, this program is completely free. The smartmontools package is responsible for monitoring hard drives and SSD drives, regardless of whether they use SATA, SCSI, SAS or NVME interfaces, it supports any type of data interface. It is capable of registering any type of warning or disk error to the main syslog of the server, it also allows sending these same warnings and errors by email to the administrator so that he can verify that everything is correct. smartd : is a daemon or process that verifies that hard drives or SSDs in a specified interval have not had any failures.

smartctl : is the command line program that allows us to verify hard drives and SSDs on demand, or we can program its operation through the typical cron in the operating system.

Sometimes this package is pre-installed in our distribution, and other times we have to install it ourselves. In most Linux based distributions we have a package called smartmontools. In Linux operating systems we have the possibility of carrying out SMART tests to check if the disk is working correctly, in addition, we have the possibility of programming these tests to minimize the impact on performance. Internally SMART has a range of values that we can consider “normal”, and when a parameter goes out of these values, that is when the alarm goes off, the BIOS/UEFI will detect it and notify the operating system that there is a failure in the system. This technology is responsible for monitoring different parameters of the hard disk, such as the speed of the disk platters, bad sectors, calibration errors, cyclic redundancy check (the typical CRC errors), disk temperature, data reading speed, time starting (spin-up), reallocated sectors counter, search speed (seek time) and other very advanced parameters that allow you to know what is important: if the hard drive is going to fail soon. Today all servers, operating systems and disks use this technology to detect problems in the hard disk, we could say that it is “universal” and that it is always used. In order to use SMART, it is absolutely necessary that the BIOS or UEFI of the server is compatible with this technology and that it is activated, in addition, it is also absolutely necessary that the disks incorporate it.
