There is a special consideration when installing TrueNAS in a Virtual Machine (VM), as S.M.A.R.T services monitor actual physical devices, which are abstracted in a VM. After the installation of TrueNAS completes on the VM, go to System Settings > Services > and click the blue toggle button on the S.M.A.R.T. service to stop the service from running. Clear the Start Automatically checkbox so the service does not automatically start when the system reboots.
The Services > S.M.A.R.T. screen displays settings to configure when S.M.A.R.T. tests run and when to trigger alert warnings and send emails.
Name Description Check Interval Enter the time in minutes for smartd to wake up and check if any tests are configured to run. Power Mode Select the power mode from the dropdown list. Options are Never, Sleep, Standby or Idle. S.M.A.R.T. only tests when the Power Mode is Never.

Tests Using Shell to View Scheduled Tests S.M.A.R.T. or Self-Monitoring, Analysis and Reporting Technology is a standard for disk monitoring and testing. You can monitor disks for problems using different kinds of self-tests. TrueNAS can adjust when it issues S.M.A.R.T. alerts. When S.M.A.R.T. monitoring reports a disk issue, we recommend you replace that disk.

SMART Namespace SMART Commands Interactive Argument Editor (TUI) Config Command Update Command SMART Namespace The smart namespace has two commands and is based on S.M.A.R.T. service functions found in the SCALE API and web UI. It provides access to S.M.A.R.T. service management methods through the smart commands.
SMART Commands The following smart commands allow you to view and edit smart properties.
You can enter commands from the main CLI prompt or from the smart namespace prompt.
