It also displays options for connecting/disconnecting from TrueCommand Cloud. When the system is not connected to TrueCommand Cloud the options are not available. The icon appears but is gray in color.

TrueNAS Enterprise compatible hardware has a (cloud with HA text) icon that shows the current status of High Availability (HA) on the system. A checkmark () cloud icon indicates HA is functional. An on top of the cloud icon indicates HA disabled or otherwise unavailable.

Task Manager

The (clipboard icon) is the system Task Manager. Click the icon to show a list of running or completed TrueNAS tasks. Tasks are sortable by their success or error State, task Method, and Progress. Typing text in the Filter field shows tasks that match the characters typed into the field. Clicking an entry shows more details about that task. This includes start and end timestamps.


The (bell icon) contains system notification messages. The icon changes to when TrueNAS creates a new alert. Clicking the icon slides out a panel from the right side of the screen that lists each alert. Dismiss or reopen alerts in this panel. Dismissing an alert does not prevent it from recurring. TrueNAS might create a new alert if the alert conditions continue to exist on the system. Configure the alert system in System > Alert Settings.


The (gear icon) contains links to various system specific options.

Change Password is a shortcut for changing the administrator (root) account password. Password required to log in to the TrueNAS web interface. Back up or otherwise memorize the updated password when changing it.
