Data partition doesn't mount automatically Manjaro

My data partition doesn’t mount automatically on boot. I have to mount it with password each time I restart my computer.
Any idea how to fix this ?
Thanks by advance for your comments.

did you try checking the configuration of the Disks & Devices in the system tray to see if the box for mount on boot is checked?

sometimes it seems those boxes can become unchecked at random, and when i find some partition is not mounted in dolphin, i look there to make sure it’s still checked.

I suspect some poolkit rules might have gotten removed in a recent update.

Make sure you have following in /etc/polkit-1/rules.d/99-manjaro.rules. Create if not there.

polkit.addRule(function(action, subject) {
    if ("org.freedesktop.udisks2.") == 0 && subject.isInGroup("wheel")) {
        return polkit.Result.YES;
