Regarding: #9471

This is to confirm that disabling Apache's reqtimeout module
Tested: Didn't work for me

https://forum.owncloud.org/viewtopic.php?f=17&t=32517
It's a summary of possible reasons.

Other issues seen, but all without a solution

[kesselb]

Thanks for reporting this issue 👍

https://github.com/nextcloud/server/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+%22expected+filesize%22

Please pick one of the issues (with similar setup) from the list above and append your issue template.

[BstAA]

Hi Daniel I don't think it makes sense to append this issue to one of the others, as I already checked for the discussed reasons:

• timeout
• large files
• Win 10 specific
• ...
  So if I really should add my issue to one of the others, please advise

[kesselb]

Fine by me. Please update your issue template and add config, apps and logs (nextcloud, webserver, etc.). There could be many reasons for this kind of error. I was running into that issue myself with a quota defined for www-data for example.

[BstAA]

Thanks! Data has already been there, but a format error hided it :-(

By the way: The trusted_domains entry 11 has already been removed without positive result.
I also moved the tempdirectory to another location with full access rights (777) and restrictive rights as original.

[kesselb]

Unable to create temporary file, Check permissions in temporary files directory.

Leads to the question: Is /media/nc-data/ncdata/tmp writeable to www-data?

[BstAA]

drwxrwxrwt 1 www-data www-data 0 Sep 17 09:13 tmp
yes, but empty all the time
as told meanwhile I changed the tempdirectory variable and created a new directory without result

also checked file system etc. But interesting is that the error
expected filesize 529008 got 8192
just reflects the possibility. As long as I try the upload files with less than 8192 Byte lenght it's working

Shall I perhaps try to move the complete Data-Dir with the help of ncp?

[kesselb]

cc @nachoparker any idea?

[BstAA]

Closed because I had to restore from backup to NC 16.0.2 to get system running again.
Did some further experiments, but nne of them showed positiv results.
Additionally the apps-store seams to be empty.
