Startup script location

[enyafox]

So I have noticed that all the scripts runs on startup. Does anyone know where the file location would be?
Thanks.

Good to hear from you!

I'm not entirely sure I understand the question. Are you asking how they work in my Debian installers?

For those projects I have it setup for them to be installed into /usr/local/bin/micon_scripts/. The startup scripts are called by systemd services at startup, the shutdown script is linked in /lib/systemd/system-shutdown/ so that it gets called at shutdown. These locations are specific to Debian with SystemD.

They Python scripts themselves aren't actually Debian/SystemD specific, you could hypothetically use them with other linux distros or even other Operating Systems if you adjust the device names in the scripts. In that case you'd use that systems startup/shutdown mechanisms to call them.

Let me know if that answers the question.

oddly enough, I've never actually done that.

off the top of my head I would write a short python script that checked the state of the button and then slept for 1 second (maybe even shorter). it would count the number of times it saw it as "pressed" and would call the desired command if the ocunt reached a certain number. you could start that with a systemd service basically the same as the fan one.

Would you be able to write the script for me please? I haven't been able to figure something out. I also have another problem (Sorry for keep on going on lol) but when displaying text and scrolling through different things, the LCD screen seems to get darker and darker. Could it be a mistake i'm making?

[1000001101000]

I can take a swing at it.

Could you post your current code?

[enyafox]

Unfortunately I've just cleared the file.

I have taken the front panel off and apart and re-seated everything. The display seems to be working properly. I just need a way to use the buttons to do different things.

[1000001101000]

I went ahead and wrote a script which shutsdown the system if you hold the power button:
https://github.com/1000001101000/Python_buffalo_libmicon/blob/master/button_daemon.py

if you put it in /usr/local/bin, mark it executable and run it as root you can test it out.

after you do that you can make it run at boot by creating the following systemd service.

/etc/systemd/system/button_daemon.service:

[Unit]
Description=Terastation Button Service

[Service]
Type=simple
ExecStart=/usr/local/bin/micon_scripts/button_daemon.py
Restart=always
RestartSec=5s

[Install]
WantedBy=multi-user.target

once you create the service file you enable it with:
systemctl enable button_daemon.service
systemctl start button_daemon.service

I haven't spent a ton of time on this topic with this device (or any other than my laptop really).

I believe the main issue with just spinning down the drives is that if your rootfs in on the drives it will spin them back up frequently to write out log entries from background tasks etc. There are ways around this but each comes with some challenges and some may not be possible for this specific device.

0. Just replace your disks with SSDs obviously, this may not be practical though running your rootfs on an old SSD and using the remaining bays for spinning data disks would work pretty well.
1. Move the rootfs to a USB stick. The device can't boot from usb but it is possible to have your /boot on the main drives but your roofts on a usb stick.
2. Suspend the device to ram I kind of doubt this SoC can do that with mainline linux and also doubt you could wake it if it did but I'm adding it to the list anyway.
3. shutoff and wake via schedule with RTC I also do not know if this is possible for this particular device using mainline linux but am somewhat more optimistic it is possible.
4. shutoff and wake via WOL I also do not know if this is possible for this particular device using mainline linux but am significantly more optimistic it is possible.

So, they do seem to spin down when not in use. I do need to go online and have a look at a more quieter fan sometime. I have changed a few values but the NAS gets quite warm lol

[enyafox]

I do have the rootfs on an ssd in slot 1. I should really also look into a 3.5' converter for my SSD

[1000001101000]

is the rootfs just on the SSD or is it raid1 across the drives like the stock firmware?

[enyafox]

The rootfs is just on the ssd and the rest are just normal ext4 drives

@enyafox I recently discovered that the USB ports on this device are enabled via a set of GPIOs that weren't all getting activated at boot. I updated my kernel patch to enable them as part of the initialization process. While I was add it I also mapped GPIO15 as a button in the kernel.

Once you update the kernel you can start managing the rear switch like a normal button/key using triggerhappy etc.

Alright thanks, do you know the baud rate that is used?

[enyafox]

And would you know what i could use to connect through serial?

[1000001101000]

115200

I use minicom on linux, PuTTy should work on windows.

[enyafox]

Unless ive got the pins wrong, im just getting the normal scrambled characters

[1000001101000]

scrambled characters usually means some issue like parity/speed/stop bits

you keep saying pins, I don't understand quite what you are referring to

[1000001101000]

I use something like this:

Still scrambled up characters

[1000001101000]

I've done that with my TSXL as recently as last week, it should work with the right settings/etc. Can you provide more detail of what tools you are using?

[1000001101000]

....maybe two weeks ago, whenever I was working on the kernel patch
