[Solved] Synology DS212j - unable to Sync

[airzoink]

Greetings! I was able to install Bittorrent Sync 2.3.6 (378) for 88F628X on my Synology DS212j. Going through the usual setup of P2P source and target i only get placeholder files (bts) showing in my NAS. Could not get the actual files to sync. I'm syncing files from my linux (ubuntu) and windows 10 box. Between windows and linux there is no problem. This happens only when i Sync with my NAS. Please help as i would like to use my NAS as a frequent backup target for all my files. Thanks!

@airzoink Any abnormal messages in Sync WebUI on your ds212j? like always showing receive queue, etc? Also, which type of folder do you use on Syno?

[airzoink]

No abnormal messages. My source and target peers connect and upload/download speeds are showing correct speeds. The only problem is all files sync to my NAS are BTS files and it never completes them unlike desktop(PC) to desktop(Linux) syncs. Any solutions?

By the way if i disconnect from the source, the file would still exist in the target folder having BTS. Then when i remove the BTS extension by renaming it manually, i now have a usable copy of the original file.

@airzoink Well, then I suggest collecting logs from all your peers and opening support ticket. We'll do our best to find our what happens.

@RomanZOk i will try what you suggest. I only see "sync.log" file. Cannot find "sync.log.<some number>.zip". Is that ok?

It's okay, it just means your logs never rotated yet.

better not do it. Sync shall itself rename bts to the file, and correctly update database. Once it's not done, this may indicate permission problem - no write access for Sync or no permission to delete bts.  See around - may be you do have the filename.txt there together with filename.txt.bts.

@Helen Regarding permissions, what setup would be proper? The thing is, even if Sync has 'finished' copying all the files, which i can check in the target folder having BTS placeholders, it does not end with 'Synced all files'. It continues with uploads and downloads indicating 100+Kb/s. I do not know what other files it is transferring or why it does not end.

[Helen]

Sync on SYNO runs under 'admin' user, so admin needs to have  rw- permissions to the filename.bts, filename and the folder itself including all parents folders. 

We got your logs , and there are indeed "Permission denied" error about all those mp3 files. So those 100Kb/s that you see - are the attempts to finish the post download jobs - delete the bts and write pieces to the file itself . So please do check permissions.

Thanks for that. Got it working!
