Disable hibernate? (was: web ui suspend causes poweroff / systemctl suspend works)

Hi,

I'm a long time user of OMV3/4 which has been chugging along nicely for ages - thanks for that!

I've decided to give OMV5 a look.

I have a fresh install of OMV5, fully upgraded, the only two "non-standard" parts would be

1. I shrank the system drive a to use part of it as storage.

2. added ethtool ... -wol to interfaces to enable wol.

The problem I have is with suspend:

- When clicking on "suspend" in the web ui the system instantly powers off. does not respond to wol, hitting the power button shows the system rebooting, not waking up from suspend.

- When issuing a systemctl suspend command manually, the systems suspends fine, responds to wol, and wakes up.

which command is is issued via the web ui? (is it different from systemclt suspend, why?)

where can I change it? or is there a better way to fix this?

many thanks!

Okay, I think I figured out what;s going on.

OMV5 prefers hibernate over suspend:

    /**
     * Put the machine in a sleep state. If suspend to disk (STD) or RAM (STR)
     * is not supported the system will be shut down. The system will be put
     * into one of the following state depending on which state is supported:
     * <ul>
     * \li Hybrid suspend (STB)
     * \li Suspend to disk (STD)
     * \li Suspend to RAM (STR)
     * \li Shut down and turn of system
     * </ul>
     * @return void
     */
    public function standby() {
        if (TRUE === $this->isStateSupported(self::STATE_SUSPENDHYBRID))
            $this->suspendHybrid();
        else if (TRUE === $this->isStateSupported(self::STATE_HIBERNATE))
            $this->hibernate();
        else if (TRUE === $this->isStateSupported(self::STATE_SUSPEND))
            $this->suspend();
        else
            $this->shutdown();
    }

But, my system doesn't support WOL from hibernate/powerdown - only from suspend.

So, the question now becomes:

how can I disabled 'hibernate' ?

thanks

(oh yeah, I also found that you can set WOL from the webui - which will overwrite your edits anyway in /etc/.../interfaces)
