Match smartmontools Drive Database entry: Smartctl 7.1 r5022 (local build)Ĭopyright (C) 2002-19, Bruce Allen, Christian Franke, Drive found in smartmontools Database. The -P show option displays if the drive is in the database, and if so, its presets, then exits: # smartctl -P show /dev/sdc Instead, SCSI/SAS and NVMe drives do not provide ATA/SATA-like SMART Attributes, so the database doesn’t contain any entries for these drives. The “Vendor Specific SMART Attributes with Thresholds “ table reported by smartctl in the previous section relies on the Smartmontools’ database for ATA/SATA drives. On larger disks, they can take up to ten hours or more. We should proceed with caution with the extended tests because their duration may impact disk wear. In the continuation of this tutorial, we will do a short test. įurther on, we see the estimated times for performing the self-tests: 2 minutes for the short one and nearly 4 hours (215 minutes) for the extended one. However, if we want to enable it, we can run “ smartctl -s on -o on -S on /dev/sdc”. It’s disabled, and we can leave it that way.

“Auto Offline Data Collection” periodically updates specific SMART attributes, but it could impact performance. That’s fine, it means that the disk is still usable. That’s good.Īfter that, we read that the “SMART overall-health self-assessment test result” is “PASSED”.

Let’s see an example using the –all flag, which prints all SMART information about a physical disk. Attribute individualism is important because drive architectures vary from model to model.

SMART technology includes a series of attributes or diagnostics chosen for each drive model. The difference between NAME and KNAME is that the former indicates the device name, while the latter means the internal kernel device name. This tree-like view of partitions is quite intuitive.

In this case, /dev/sda contains an LVM with encrypted partitions. Then, for each disk, we can list its partitions, for example: $ lsblk /dev/sda -o NAME,KNAME,FSTYPE,MOUNTPOINT,SIZE The detailed information provided by lshw helps us not to be mistaken. First, let’s identify the disks: # lshw -class disk There are several methods to find all storage devices. Let’s look at some examples: /dev/hd, /dev/sd, /dev/vd, /dev/nst*, /dev/sg*, /dev/twe, and so on. In the rest of this tutorial, we need to know which device files identify our disks and their partitions.
