Musyanon Posted September 11, 2020 Share #1 Posted September 11, 2020 Hello everyone, I have install DSM on my Qnap TS559 pro+, all work without problem except the hibernation. I have the problem with 6.2.3 and I have downgrade to 6.2.2 but same problem. Anyone know how can I resolve the problem ? Quote Link to comment Share on other sites More sharing options...
Musyanon Posted September 11, 2020 Author Share #2 Posted September 11, 2020 (edited) Finaly it work in 6.2.2, I have set the setting to 10 minutes, but it take more like 15 minutes to go hibernation....

Mai_Mai Posted October 4, 2020 Share #3 Posted October 4, 2020 (edited) Hello Musyanon. Great to hear you recovered hibernation in DSM 6.2.2. I consider downgrading form 6.2.3 to 6.2.2 too. Can you describe the steps you followed to successfully downgrade ? I fear to loose my data and parameters and I didn't found an actual how-to.

Musyanon Posted October 4, 2020 Author Share #4 Posted October 4, 2020 Sorry, I have do a clean install without data... You will need create a backup. Quote Link to comment Share on other sites More sharing options...
Mai_Mai Posted October 11, 2020 Share #5 Posted October 11, 2020 Thanks for the feedback. I can't loose all my data so I will not do as you did. And I'm not enough confident to apply the tutorial I found in the forum. I stop the NAS manually waiting for a fix. Quote Link to comment Share on other sites More sharing options...

There are a lot of reasons it may not be working, but mostly log messages written recurrently to /var/log due to hardware status failures resulting from non-Synology hardware. That's one of the reasons I've posted on some filtering of smart and scemd errors, but there are many errors and they differ depending on the platform you have installed. Unfortunately not a simple or single solution works for all. Quote Link to comment Share on other sites More sharing options...

My NAS is an HP microserver gen8 using DSM 6.2.3-25426-2 and an additional Intel NIC. I'm using a script to start the nas with WOL function and I appreciate it shuts off automatically after some time of HDD inactivity. I' didn't try yet the workaround suggested by flyride.

Mai_Mai Posted November 12, 2020 Share #9 Posted November 12, 2020 Just a quick feedback to tell I managed to restore hibernation with the workaround found on an another post : I accessed to my NAS with Putty ; edit scemd.conf in /etc.defaults/syslog-ng/patterndb.d/ using vi and replace : destination d_scemd { file("/var/log/scemd.log"); }; with : destination d_scemd { file("/dev/null"); }; Reboot and that's all ! 1 Quote Link to comment Share on other sites More sharing options...

nadiva Posted October 17, 2021 Share #12 Posted October 17, 2021 this is one frustrating feature i could never fix. There's no hibernation on my Ds918 image, drives spin up as soon as i spin them down manually (hdparm). Meanwhile electricity costs explode, my electricity provider bankrupted, and the drives which are needed for 1hour a day, make noise reminding me of this every day, just like the main fan makes horrid noise (unfixable issue on HP Gen10 thanks to weird fan setup, i've burnt one server playing with cables/adapters/regulators). surprising to see someone can spin down disks, i'd believe a complete hibernation is possible (not in my case), but how you can spin down disks on live system with / mapped to the RAID1 (md0)? the good ole' trick with installing on one drive, then add raid drives doesn't work as DSM will expand on all drives as soon as it detects them. i have 2 standalone drives and 4 RAID drives, so i could still have a "system RAID" active if i shrinked the system RAID(+swap) from 6 to 2 hdds. but i worry DSM would complain. i'd have to also create a dummy allocation there to make sure no RAID fits. the fix above didn't work. i remember very well drives couldn't spin down on an empty installation either. all i am reduced to now is read the bad advices how running drives 24/7 is 'healthy' (a hoax that spreads on internet like "BTRFS is not good for RAID").

(case fans, CPU fan, ...) Thanks -a- 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 . 1 1 Quote Link to comment Share on other sites More sharing options...
TheRealMaN_ Posted Monday at 06:17 AM Share #16 Posted Monday at 06:17 AM On my system the disk sleeps and never wakes up on its own only after I set a sleep time manually via terminal command with root user: hdparm -S 60 /dev/sd{X} I've tested different time values and came to the conclusion that disk can only sleep when a time is no more than 5 minutes. If its greater than that - the disk would never enter the hibernation state. You also can force it to hibernate immediately using command: hdparm -y /dev/sd{X} apart from that I've only set "Hibernation" option in "Control Panel" -> "Hardware & Power" -> "HDD Hibernation" to 10 minutes and also ran script from https://github.com/AlexFromChaos/synology_hibernation_fixer Quote Link to comment Share on other sites More sharing options...
