[Hibernation doesn’t work]

Hello @Sak1s

 

Is this trick "universal"?

I need to enable hibernation on the following rig:

 - DS3622xs+, TCRP 0.9.3 with friend, DSM7.1.0-42661 (I'd like to upgrade DSM7.1.1-42962 if that's possible, still looking into it)

 - bare metal

 - Asus MB with Z77 chipset

 - i7-3770 (Ivy Bridge)

 

Does hibernation only spin down the disks or can it also stop the fans? (case fans, CPU fan, ...)

 

Thanks

Hello @asheenlevrai

 

I am quite sure that hibernation just only spins down the disks . 

I think the original synology hardware use special sensors for controlling the fan speed via pwm, so in that way you have to build additional kernel modules according you motherboard and modify the DSM scripts that controls the fan speed (better check your motherboard bios for quiet mode or similar powersave modes)

 

I checked this symlink with DS3617xs  and DS3622xs+ and it worked fine.

 

As for the update from DSM7.1.0-42661 to DSM7.1.1-42962 , you can manually update to DSM7.1.1-42962 , boot to TCRP loader and run ./rploader postupdate in order to recreate initrd and patch the kernel image but i lack of such an experience .

Hi sak1s, I have tried your advice. It seems now the HDD hibernation is working fine!! But now It happens that If I try to login to the nas on the usual webpage I have instead a white page…. This seems to happen after a while (I don’t understand if suddenly after the first hdd hibernation or later..)
the shared folders continue to work but no login page. I have to shutdown the nas through power button.

I have latest dsm 7.1.1 update 2 on my HP N40L with tcrp 0.9.3.0 

 

 

 

Hi Stefano ,

i have the feeling that the problem with the "white page"  is not relative with the symlink of  scemd.log .

From my little experience with the DSM7 ,never happen to me .

More over, i had install more than 40times DSM on a lenovo PX4-400D, with different versions, just to check if that my system is stable and  which version of DSM is more accurate 

 

Also in most cases , i was just logged in  to webpage to see that disks  just wake up from hibernation . 

 

Do you try to ping your machine when you have a blank page  or Open Google chrome developer Console ?

 

Also check the nginx logs  under /var/log/nginx/error.log

try the following :

 

Connect with ssh as root and force a symlink 

 

ln -sf /dev/null /var/log/scemd.log
