lacie 5 big network v.1 please support for fvdw

[fvdw]

Hi tatae

I will try to compile a linux 3.9.5 kernel for the 5big1 coming days. Are you willing to test it ?

[taetae]

Sure no problem ... I'm copying all my stuff on and there are many gb hd and only way to do that is through ethernet I think ...

for the moment I'm copying a 779 gb hd but I have many terabytes to be paid ...

when you need to mail in a timely fashion and I will try to do the thing ....

the ethernet is very slow to load things 778gb in 21 hours ....

the temperature to 47 ° is normal?? I do not think the fan is never active

[fvdw]

47 oC is still acceptable but becoming critical. I would run it when it exceeds 55 oC
You need to check if the fan is running or not

[taetae]

no fan is stopped ...


Today 49 °

you can not do anything to fix it? I put the fan near perchpè I would not have any problems with the hd cost me a lot :-(

[fvdw]

normally the fan should start automatically on this mainboard as far as I know. It has chip measuring temp and controller for the fan.
In the kernel setup there is as far as I can check only possibility to detct if it is running or not and there is is one GPIO pin that can force fan start trip point 1 Maybe we can try to set this pin to force start of the fan.

First we try if we can "export" this GPIO pin to userland, then we also can control it without recompiling the kernel.

To export it to userland connect via ssh using putty and give command

Code: Select all

echo 16 > /sys/class/gpio/export

This will result in the pseudo-files for pin 16 showing up under /sys/class/gpio/gpio16 as:

/sys/class/gpio/gpio16/direction
/sys/class/gpio/gpio16/value
etc...

You can set the direction to either 'in' or 'out':
Set it to "out"

Code: Select all

echo out > /sys/class/gpio/gpio16/direction


And now set the pin value to 1:

Code: Select all

 echo 1 > /sys/class/gpio/gpio16/value

If that doesn't start the fan try

Code: Select all

echo 0 > /sys/class/gpio/gpio16/value

ps the compile of the 3.9.5 kernel for 5big1 succeeded, I only need to bring back the size to 2 MB as 5big1 can not load bigger kernels.


Try these combinations one by one to see if it starts the fan
so direction: out value: 1 if the fan doesn't start try direction: out value: 0

I think I found the fan chip driver (g762 used by lacie) in the latest linux releases, I ported it to 3.9.5 it it compiled ok :punk . So maybe we can get the fan up and running normally now. Still struggling to bring the kernel size down to 2 MB

[taetae]

Code: Select all

~ # echo 16 > /sys/class/gpio/export
sh: write error: Invalid argument
~ #


[fvdw]

so it doesn't want us to export this pin. That track we can forget then

I am finished with the 3.9.5 kernel I will sent a pm soon

[taetae]

I have to do some particular backup or I'll have the operation as now? You know, I almost uploaded on 10 tb hd
