btsync inhibits disk hibernation / Interaction with .SyncID-File

Recommended Posts

Hey, i have the same problem with a Western Digital MybookLive NAS. btsync is preventig it from hibernating. In addition to the .SyncID file I thing the sync.log is also a problem as it gets updated almost every second with "Incoming connection from... " messages.

hi!

 

i can confirm this bug. btsync keeps active on my ds 412+ and thus stops the system from going to hibernation. the hibernation log reads:

Jan 24 15:11:48 NAS kernel: [ 2171.580154] [/usr/local/btsync/var/settings.dat] opened by pid 11653 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Jan 24 15:13:35 NAS kernel: [ 2278.198996] [/usr/local/btsync/var/sync.dat.new] opened by pid 11660 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]

i'm running the latest ds software (DSM 4.3-3810 Update 4) and BTSync Version 1.2.82. I have only one shared folder and it's readonly, so there is absolutely no need for BTSync to access the files (they won't change unless BTSync changes them because of an external update).

 

With this bug BTSync is not useable, the DS would keep running 24/7 without any need.. =(

0xdefec,

 

Yes. Please try 1.3.80, BTSync became more friendly towards sleeping HDDs. Make sure you set folder_rescan_interval to larger value to make sure HDDs are not waken up by rescan.

hi!

 

Btsync keeps accessing .SyncID files every ten minutes

Apr  3 18:02:55 NAS kernel: [369020.784442] [/volume1/andreas/cloud/.SyncID] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:11:13 NAS kernel: [369519.088913] [/usr/local/btsync/var/sync.dat.new] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:12:41 NAS kernel: [369607.324039] [/volume1/andreas/cloud/.SyncID] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:12:56 NAS kernel: [369621.498196] [/volume1/andreas/cloud/.SyncID] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:21:13 NAS kernel: [370118.714891] [/usr/local/btsync/var/sync.dat.new] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:22:42 NAS kernel: [370208.167892] [/volume1/andreas/cloud/.SyncID] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:22:56 NAS kernel: [370222.141964] [/volume1/andreas/cloud/.SyncID] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]Apr  3 18:31:13 NAS kernel: [370718.306918] [/usr/local/btsync/var/sync.dat.new] opened by pid 20699 [u:(/usr/local/btsync/bin/btsync), comm:(btsync)]

my config file:

{   "device_name": "NAS",  "storage_path" : "/usr/local/btsync/var",  "pid_file" : "/usr/local/btsync/var/syncapp.pid",  "webui" :  {    "listen" : "0.0.0.0:8888",    "login" : "admin",    "password" : "xxx"  },  "folder_rescan_interval" : 21600}

I have configured one shared folder (named cloud) and run the 32bit version of btsync for linux.

i'm currently investigating another issue on this synology unit which might correlate with the hibernation. so please ignore my last message until i know for sure it's related to btsync.

 

@dahaniel there is an option in synology NAS to debug hibernation issues.

nope, sorry. disabling btsync --> NAS goes to sleep after 10 minutes. enabling btsyns --> no sleep. I could reproduce this several times. The logs from above are still correct, some files get accessed every 10 minutes although folder rescan interval is set very high. I disabled the webui and set the config via file:

{   "device_name": "NAS",  "listening_port": 55555,  "storage_path": "/usr/local/btsync/var",  "pid_file": "/usr/local/btsync/var/syncapp.pid",  "check_for_updates": false,  "use_upnp": false,  "folder_rescan_interval": 43200,  "shared_folders" :    [        {        "secret" : "XXX",        "dir" : "/volume1/andreas/cloud/",        "use_relay_server" : false,        "use_tracker" : false,        "use_dht" : false,        "search_lan" : false,        "use_sync_trash" : true        }   ]}

Hi RomanZ,

 

I noticed many hash IDs in the debug logs. before I post them here, could any information from the debug logs be used to access files from the shared folders? or any other privacy issues?

 

thanks for your help!

0xdefec,

 

It can't. ShareID is not a secret and cannot be used to access your shares. Your debug log is going to reveal IP addresses, files and folder names. You can throw it to my PM if you don't want to reveal it to public.

BTSync 1.3.94 still prevents disk hibernation on Synology NAS's.

 

It looks like it is still writing sync.dat.new every 10 minutes regardless of the setting of the rescan interval.

 

Any chance of a resolution or a configuration setting for when btsync writes sync.dat

I'm having the same problem with my Synology NAS. Since installing BTsync, my HDDs no longer go into deep sleep and hibernate anymore. It's rather frustrating.

 

I've decided to disabled BTsync and stop using it until this issue is resolved.

 

Are the developers confident the problem will be fixed in 1.4? Is there any news in regards to this?

@all,

 

Please, wait for 1.4. release and give it a try. If the problem remains, write to syncapp@bittorrent.com right away. Don't forget to attach full debug logs from NAS, describe your setup in details, put the link to this topic. Hibernation logs would be much appreciated. Thank you!

Same issue. Disks won't go into hibernation anymore. When I disable BTSync the problem goes away.

 

Synology DS1512+
