![]() etc/nf DEVICESCAN -m be able to send the email externally (i.e. To have an email sent when a failure or new error occurs, use the -m option: Now your USB disk will be monitored even if the /dev/sd X path changes during reboot. Note that you may additionally need -d removable for smartd to work. Now to tell smartd to monitor that disk simply use the /dev/disk/by-uuid/ path. I know that my USB disk attached to /dev/sde during boot. To monitor for all possible SMART errors on externally connected disks (USB-backup disks spring to mind) it is prudent to tell smartd the UUID of the device since the /dev/sd X of the drive might change during a reboot.įirst, you will have to get the UUID of the disk to monitor: ls -lah /dev/disk/by-uuid/ now look for the disk you want to Monitor To monitor for all possible SMART errors on /dev/sda and /dev/sdb, and ignore all other devices: Note this is the default smartd configuration and the -a parameter, which is the default parameter, may be omitted. To monitor for all possible SMART errors on all disks, the following setting must be added in the configuration file. Smartd respects all the usual systemctl and journalctl commands. To start the daemon, check its status, make it auto-start on system boot and read recent log file entries, simply start/enable the rvice systemd unit. For more complete information, read the examples and comments within the configuration file, or read nf(5). The configuration file syntax is esoteric, and this wiki page provides only a quick reference. It can be managed with systemd and configured using the /etc/nf configuration file. The smartd daemon monitors SMART statuses and emits notifications when something goes wrong. (Discuss in Talk:S.M.A.R.T.) #!/bin/bashįor d in `smartctl -scan -d scsi | cut -d' ' -f1` doĭrive_values="$" Long scripts should be maintained elsewhere. Reason: The wiki is not a code development platform. # smartctl -a /dev/ device Generate table with attributes of all disks You can also view a list of recent test results and detailed information about a device: If this happens get your data off the disk and to someplace safe as soon as you can." "If the device reports failing health status, this means either that the device has already failed, or that it is predicting its own failure within the next 24 hours. You can view a device's overall health with the -H flag. # smartctl -t conveyance /dev/ device View test results Use -t/ -test= test_name flag to run a test: The -c/ -capabilities flag prints which tests a device supports and the approximate execution time of each test. Conveyance: identifies if damage incurred during transportation of the device. ![]() Extended or Long: the test is the same as the short check but with no time limit and with complete disk surface examination,.Short: runs tests that have a high probability of detecting device problems,.There are three types of self-tests that a device can execute (all are safe to user data): For example, specifying -device=ata tells smartctl that the device type is ATA, and this prevents smartctl from issuing SCSI commands to that device. If SMART is available but not enabled, you can enable it: # smartctl -info /dev/sda | grep 'SMART support is:' SMART support is: Available - device has SMART capability. The -i/ -info option prints a variety of information about a device, including whether SMART is available and enabled: Smartctl is a command-line tool that "controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS hard drives and solid-state drives." ![]() That done, you can manually #Run a test and #View test results, or you can use #smartd to automatically run tests and email notifications. ![]() You can use #smartctl to check for and enable SMART support. SMART support must be available and enabled on each storage device to effectively use these tools. Install the smartmontools package to use these tools. The smartmontools package contains two utility programs for analyzing and monitoring storage devices: smartctl and smartd.
