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 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

hello everyone, try the following : Connect with ssh as root and force a symlink i use DSM 7.1.1-42962 Update 2 and disk hibernation works
