There are several -M directives that change when and how often reports are sent. usr/share/smartmontools/smartd-runner is a script that basically saves the report to a temporary file, and then runs anything it finds in /etc/smartmontools/run.d/ take a look there to understand what you already have (there should be a script that mails the report). Mail a report to the 'root' account in case of trouble ( -m) īut instead of the mail command, it will execute /usr/share/smartmontools/smartd-runner and feed the report to it ( -M exec program). Scan for all ATA/SCSI devices ( DEVICESCAN). In this example (which is the default for Karmic), smartd will: There should be one uncommented line, similar to: DEVICESCAN -m root -M exec /usr/share/smartmontools/smartd-runner Again, use your favourite text editor to open this file. How smartd is going to scan the disks and what it will do in case of errors is controlled by the daemon configuration file, /etc/nf. For example (using vim): sudo vim /etc/default/smartmontools. Open the file /etc/default/smartmontools with your favourite text editor. You can run Smartmontools in the background and have it check drives and email when there are issues: It's a nice graphical frontend to smartctl it shows all SMART values, and highlights those that indicate old age or impending failure, plus you may run tests on demand:Īs usual, you may install it from Synaptic or running sudo apt-get install gsmartcontrol.Īdvanced: Running as Smartmontools as a Daemon Note: This also works for IDE drives in new kernels that are being run through the SCSI stack and show up as /dev/sdX To display detailed SMART information for a SATA drive, type: sudo smartctl -a -d ata /dev/sda To display detailed SMART information for an IDE drive, type: sudo smartctl -a /dev/sda You can view a drive's test statistics by typing: sudo smartctl -l selftest /dev/sda You can initiate the test by typing: sudo smartctl -t long /dev/sda The most useful test is the extended test (long). To find an estimate of the time it takes to conduct each test, type: sudo smartctl -c /dev/sda There are three types of test that can be conducted on a drive: You may run any type of test while the drive is mounted although there may be some drop in performance. In the case that SMART is not enabled for your drive, you can enable it by typing: sudo smartctl -s on /dev/sda SMART support is: Available - device has SMART capability. The last two lines may look something like this: This will give you brief information about your drive. To ensure that your drive supports SMART, type: sudo smartctl -i /dev/sda You can install the smartmontools package from the Synaptic Package Manager (see SynapticHowto), or by typing the following into the terminal: sudo apt-get install smartmontools 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. 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. Smartmontools is a set of applications that can test hard drives and read their hardware SMART statistics. Advanced: Running as Smartmontools as a Daemon. Which of these do I check? The /dev/nvme0n1p2 is my primary data partition, but I also want to make sure the others aren't corrupt, so presumably I would want to check one of the "parent" partitions. The general usage for smartctl is to run something like: sudo smartctl -i /dev/sdX Fortunately, rebooting has temporarily resolved the issue, but I'm trying confirm that the issue is a degraded ssd and not something else, like a faulty motherboard. My laptop, which has a NVMe solid state drive, has been crashing somewhat frequently recently with strange disk read errors. How do you check the health of an NVMe ssd using smartctl on Ubuntu?
