Understanding the Home Directory in TrueNAS

In TrueNAS, the home directory is the default location for a user's files and directories. By default, the home directory for a user is set to /mnt/data0/, where username is the name of the user. However, in some cases, you may need to change the home directory for a user. For example, if you have added a new dataset and want to store the user's files there, you will need to change the home directory.

Why Can't I Change the Home Directory?

If you are unable to change the home directory for a user in TrueNAS, it may be due to one of the following reasons:

• The $HOME variable is not set for the user. The $HOME variable is a system variable that stores the path to the home directory for the user.
• The new home directory does not have the correct permissions or ownership.
• The new home directory is not located on a mounted dataset.

Changing the Home Directory in TrueNAS

To change the home directory for a user in TrueNAS, follow these steps:

1. Connect to your TrueNAS system using SSH.
2. Check the current home directory for the user by typing echo $HOME.
3. If the $HOME variable is not set for the user, set it by typing export HOME=/mnt/data0/etc/passwd, replacing /mnt/data0/etc/passwd with the path to the new home directory.
4. Change the ownership of the new home directory by typing chown user:user /mnt/data0/new_home_directory, replacing user with the username and new_home_directory with the name of the new home directory.
5. Change the permissions of the new home directory by typing chmod 700 /mnt/data0/new_home_directory.
6. Edit the /etc/passwd file to change the home directory for the user. You can use the vi or nano editor to do this. Look for the line that starts with the username, and change the home directory by modifying the home directory field.
7. Save and exit the editor. The change will take effect immediately.
