Files not syncing

querolus · March 31, 2018, 2:18pm

I have investigated a little bit more… I have manually uploaded one of the conflicting files manually and it does upload perfectly through the web interface. The problem is that despite being uploaded in the server it is not sync with the local folder so it is not downloaded to the folder where it should be… Where do you think could the problem be?

@boydhako have you been able to solve this issue? If not, could you please provide your settings so we can see if there is anything in common? I have to say that i have not changed anything of the default set up provided by the installer and, so far, with all previuos versions, owncloud worked smoothly. It is clearly an issue regarding file size (because small files do sync perfectly). The web uploaded works normally so I guess it is something related to the client…

If nothing helps then i think you can still follow the previous advice:

Ok, i’ll do that… It seems to be much higher activity at the github forum than around here anyway

querolus · April 1, 2018, 2:16pm

Thank you very much anyway for your help

anon21401411 · April 1, 2018, 3:00pm

I think there is quite some activity in here. But from what i know in here mostly users are around and those have often not that much knowledge about such special issues you’re currently struggling with.

If you’re creating a bugreport then i think it would be great if you could post a link to it in this thread so readers can follow it.

Needs info Server Involved

### Expected behaviour Synchronize files properly. ### Actual behaviour Som…e files are not synced using the Windows Desktop client. It seems related to filesize because small files sync perfectly. It all started to happen after the last upgrade. The client does not upload any big file (checked files over 8Mb) and does not download some big files (some files are downloaded and some not). Before upgrading to latest versions everything worked fine. It is not a matter of the server because files of any size can be uploded through the web uploader or through the Android App. I tried to find help in the forum and found another guy with same problem. There was not any change in the Bluehost server and, as mentioned, everything started after the latest upgrades. Hope you can help. ### Steps to reproduce 1. Explained above 2. 3. ### Server configuration Operating system: Windows 10.0 Pro Web server: Shared Server (Bluehost) Database: MySQL 5.6 PHP version: 5.4 ownCloud version: 10.0.7.2 Storage backend (external storage): no ### Client configuration Client version: 2.4.1 Operating system: Windows OS language: Spanish Qt version used by client package (Linux only, see also Settings dialog): Client package (From ownCloud or distro) (Linux only): Installation path of client: C:\Program Files (x86)\owncloud ### Logs Please use Gist (https://gist.github.com/) or a similar code paster for longer logs. ```Template for output < 10 lines``` 1. Client logfile: Output of `owncloud --logwindow` or `owncloud --logfile log.txt` (On Windows using `cmd.exe`, you might need to first `cd` into the ownCloud directory) (See also http://doc.owncloud.org/desktop/2.2/troubleshooting.html#client-logfile ) [owncloud_client_log.txt](https://github.com/owncloud/client/files/1866438/owncloud_client_log.txt) 2. Web server error log: 3. Server logfile: ownCloud log (data/owncloud.log): [owncloud.log](https://github.com/owncloud/client/files/1866426/owncloud.log)

Hope they can find the problem. If it is solved i will keep you posted

And thank you @anon21401411 for your suggestions

Hi @anon21401411 @boydhako and @bar the issue is solved. You can follow the link to the github issue above. Basically it is solved when creating an Environment Variable OWNCLOUD_CHUNKING_NG and set its value to 0.

Hope this solution helps you as well.

Thanks!

Great news. Seems @alfageme had provided some background on this in the issue:

We don’t currently support shared hosters since they’re quite painful to deal with. Your problem might be related to limited/shared access to a DB/permanent storage when using chunking. However, there’s a way to force the client to use the old algorithm and endpoint. Can you give a try switching the OWNCLOUD_CHUNKING_NG env.var. and restart the client? (i.e. launch the client with this variable set to 0 on cmd)

and the issue:

Something that changed sensibly from version 2.2.4 to 2.3.* is the use of the new chunking algorithm (#4019) if the server reports it - can you give a try switching the OWNCLOUD_CHUNKING_NG env.var and restart the client? (i.e. launch the client with this var. set to 0)

Its not the first time i had read about issues on shared hosters due to limited resources not able to handle the requirements of ownCloud.

And i think especially the second text explains why this issue was showing up after an upgrade from 9 to 10. Probably only 10 reports this “new chunking” and thus the client had used it directly.

Everytime i have such an issue i tell myself to set up a server myself… I have some knowledge on how to set up things but not at all about programming or systems and i risk not being efficient. I will try…

Thank you @alfageme and @anon21401411

Thanks for this. Where do I set the environment variables?

anon21401411 · April 10, 2018, 6:36pm

I think this depends on your used operating system:

Unfortunately the problem continues. In MacOS, when I type “env” in terminal, I do see the line

OWNCLOUD_CHUNKING_NG=0

But the behaviour doesn’t change: uploads for files of ~15 Mb or larger fail.
In the log I see many lines like the following:

||Documents/foo.pptx|INST_IGNORE|Up|1524759756||15491065||9|Server replied “406 Not Acceptable” to “PUT https://foo.com/cloud/remote.php/dav/uploads/foo/4091971421/00000000” (skipped due to earlier error, trying again in 3 hour(s))|0|0|0||||

for all of the larger files that cannot be uploaded.

boydhako · September 18, 2018, 10:17am

Sorry, been busy. Yeah, Mac OS X chunking thing doesn’t work for the client.

In short, it’s still broke.

boydhako · September 18, 2018, 10:38am

That’s a negative my friend…

# export OWNCLOUD_CHUNKING_NG=0

and then restarting the client didn’t do anything for the Mac OS X client.

Hey,

maybe some one needs to re-open the created bugreport posted previously?

adrian_li · February 2, 2019, 3:08pm

hi i hv similar issue here on PC client, hv this issue been solved?

pdwalker · November 17, 2019, 12:45am

ownCloud server 10.3.1
ownCloud client 2.6.0 build 12703 for Mac OSX
Ubuntu 18.04.03

I too had the syncing problem until I set the OWNCLOUD_CHUNKING_NG=0 environment variable and restarted the client.

Does anyone have any idea why I need to do this? Is there any server/apache/php setting I can change to make the ownCloud client work correctly by default? I cannot ask my users to set environment variables.

Any advice would be greatly appreciated.

anon21401411 · November 17, 2019, 10:36am

Hey,

an ownCloud developer seems to have provided some background previously why this is needed on specific environments:

If i’m understanding this correctly the env.var variable is the only known workaround for such environments with this kind of restrictions / problems and which can’t handle the chunking requests done by ownCloud.
