0 FiberInternetUser Posted June 29, 2018 Share #2 Posted June 29, 2018 Hello, If you are running DSM 6.2 .. go to Control Panel | Hardware & Power ... Scroll down to "LED Brightness Control" and drag the slider to the OFF position. Quote Link to comment Share on other sites More sharing options...

0 RKG90 Posted July 3, 2018 Author Share #4 Posted July 3, 2018 (edited) So i updated to DSM 6.2 with jun 1.03a2 918+ Now the errors is coming every 6 seconds and it is not even going to hibernation. No one have a solution, on how to make DSM not read the brightness of the LED ? Edited July 3, 2018 by RKG90 Quote Link to comment Share on other sites More sharing options...
0 Niklaus Posted March 7, 2019 Share #5 Posted March 7, 2019 I solved this on my 6.1 station by removing scemd.log and link it to /dev/null, which is kind of logging to nowhere. Of course, you won't be able to see the log contents this way. This can be done by enabling ssh, log in and execute the following commands. sudo -i rm /var/log/scemd.log; ln -s /dev/null /var/log/scemd.log I don't remember if a restart was needed but I think it does. I always wanted to test if I can redirect the logs to an UBS stick but I didn't have the time for this. Quote Link to comment Share on other sites More sharing options...

Hi
I just built a NAS server with at ASROCK J3455-itx
everything is working perfectly except hibernation.
I think i figured out it has something to with the computer trying to read the LED brightness. But it cant and wakes up again.
i found this in scemd.log:
2018-06-29T19:37:31+02:00 Grevy-NAS scemd: led/led_brightness.c:244 Fail to read /usr/sbin/i2cget 2018-06-29T19:37:31+02:00 Grevy-NAS scemd: led.c:35 SYNOGetLedBrightness fail() 2018-06-29T19:37:51+02:00 Grevy-NAS scemd: event_disk_hibernation_handler.c:42 The internal disks wake up, hibernate from [Jun 29 19:37:27] 2018-06-29T19:48:16+02:00 Grevy-NAS scemd: led/led_brightness.c:244 Fail to read /usr/sbin/i2cget 2018-06-29T19:48:16+02:00 Grevy-NAS scemd: led.c:35 SYNOGetLedBrightness fail() 2018-06-29T19:48:34+02:00 Grevy-NAS scemd: event_disk_hibernation_handler.c:42 The internal disks wake up, hibernate from [Jun 29 19:48:15] 2018-06-29T19:58:35+02:00 Grevy-NAS scemd: led/led_brightness.c:244 Fail to read /usr/sbin/i2cget 2018-06-29T19:58:35+02:00 Grevy-NAS scemd: led.c:35 SYNOGetLedBrightness fail() 2018-06-29T19:58:55+02:00 Grevy-NAS scemd: event_disk_hibernation_handler.c:42 The internal disks wake up, hibernate from [Jun 29 19:58:35] 2018-06-29T20:09:27+02:00 Grevy-NAS scemd: led/led_brightness.c:244 Fail to read /usr/sbin/i2cget 2018-06-29T20:09:27+02:00 Grevy-NAS scemd: led.c:35 SYNOGetLedBrightness fail() 2018-06-29T20:09:40+02:00 Grevy-NAS scemd: event_disk_hibernation_handler.c:42 The internal disks wake up, hibernate from [Jun 29 20:09:26]
As you can see it keeps on waking up right away and go to hibernate 10min after.
Can someone tell me how i turn off the brightness reading ?
