Just wanted to say thanks for all your hard work. This thread pointed me in the right direction and was able to get a simple activity monitor for my individual HDD leds written. Thanks again.

I have the ex495 running debian squeeze, and was able to install the mediasmartd, but the leds are in the wrong order. Is there a config somewhere where I can change the order?

@merelin I installed mediasmartserverd 32 bit deb on my Acer H340 running Ubuntu 10.04. I just upgraded to Ubuntu 12.04, which resulted in a broken system. I had to spend a day to fix (http://ubuntuforums.org/showthread.php?t=1967660) the upgrade. The issue stemmed from your deb package, where the description field contains multiple empty lines. Can you remove them so others don't run into the same issue in the future? Thanks for your contribution.

Thanks for pointing that! The new versions are attached.

Hello,

I know it is an old thread, but it helped me a lot.
I have a newer version of the Acer EasyStore, the H342.
It has a different south bridge, ICH9.
I modified the original driver (written by Alexander Georg) to
suit the new southbridge. It means different GPIO addresses.
With this driver I can control the lights of my server.
I have read that somebody was looking for H341 driver, I think this is
good for that too, but I don't have hardware to test.

I have attached the altered source code.
Feel free to use it!

Hello!


First of all: Thanx for ur work!

I just get an object file from ur Makefile. Could u please tell me how to use it?

Regards, Holger

Hello Holger!

You can just load the module with insmod.

Then a few new folders will appear in /sys/class/leds

h342:InfoLedBlue/
h342:InfoLedRed/
h342:PowerLed/
h342:USBLight/

Each has a file named "brightness" and another "blink" along some other.

If you echo 255 or 0 into these files, you can control the on/off and blinking state of the corresponding leds. The brightness value is logically inverted except for PowerLed.
For example:

will turn on the "USB BACKUP" led, and

will make it blink.
The backslash (\) is needed to escape the special meaning of the colon(:).

Hope it helps,

Gyuri

Hello!

Thanx fpr ur replay, but I got the following errormessage:

root@Server-HH:/tmp/h342# insmod /tmp/h342/leds-h342.ko
insmod: error inserting '/tmp/h342/leds-h342.ko': -1 Unknown symbol in module
root@Server-HH:/tmp/h342#


Do u have an idea?

regards, HOlger

Could you please copy the output of dmesg | tail? Just after the failed insmod. It tells which symbol is unknown

The Messagelog says the follwoing:

Aug 6 22:33:31 Server-HH kernel: [5275006.499927] leds_h342: Unknown symbol led_classdev_unregister (err 0)
Aug 6 22:33:31 Server-HH kernel: [5275006.501367] leds_h342: Unknown symbol led_classdev_register (err 0)

Thx, Holger

I use the 3.2.0-27 kernel (precise pangolin), but if I am right, the previous versions need the led-class module to be explicitly loaded. The missing functions are in that module.
So run:


You can also insert the leds-h342 module with modprobe.
First, it must be in the right directory (/lib/modules/`uname -r`/kernel/drivers/leds) (`uname -r` gives the kernel version).
Second, you must run "depmod -a" to register it's dependencies.
Then modprobe will automatically load all the modules needed by leds-h342, so the only command will be

Note that if doing with modprobe, you don't need the .ko extension
because you write the module name instead of the file that contains it.

I hope you will succeed this time!

Hello!

The module is loaded and works fine for the leds on the leftside. Is the no support for the four HDD Leds on the right side?

regards, Holger

This driver was not supporting those LEDs, they are connected to another chip.
This functionality is supported by the mediasmartserverd program.
That doesn't support H342 as far as I know, I plan to modify that too so it will.

@merelin Can you adjust your .deb package? My led order is off by 1. From bottom to top, sda is being lit on the 2nd bay, sdb is lit on the 3rd bay, sdc is lit on the 4th bay, etc. Hdd bay #1 is not lit at all. Much appreciated if you can shift the numbering down by 1. This is for a debian squeeze install.
thanks!

@mugenbb6 There is no hardcoded numbering actually. I'd suggest that you do the following:

1. Run
2. Give me the output of
3. Give me the output of
4. Download mediasmartserverd.tar.gz attached, unpack and run like Give me the output it produces.

Cheers!
