Hi,
I just installed ownCloud on my Root-Server.
So far, everythinks works perfect.
Just the SFTP-Connections to my External Storeage makes problems:
When I try to upload bigger files (e.g. > 25 MB) the file never will be uploaded to the external storeage. Smaller files are working and even bigger files (> 250MB) are working when I upload them directly to my server (not external stoareage).
I think there is a problem that my ext. storegage using the streaming connection or something like that. Can I somehow activate the “temp-folder” for the SFTP connection?`
Thanks!
Regards.
Hi, it was activated before, but I disabled is, because I had to much problems.
So, the answer is “no, I´ve mod_sec not active right now”
Hello,
Did you see any of the other modules that are troubles makers in the list running on your server?

No, in my opinion not. Which one do you mean/know?
I also tried to mount via SSHFS and then connect to it via “Ext. Storeage” -> “Local”, but that did not work. I think beacuse of the permissions…
Hey,
maybe this previous hint could give you some more info on your issue?
Thanks, but I did a lot of the stuff described there…
Is it possbile to use a “sshfs” mounted folder as “local” ext. storeage?
Or is it possbile to activate upload using the temp-folder fpr SFTP?
Hey,
i think what the documentation is trying to tell you is to look into your log files to see where the error / issue from failed uploads above a specific size is coming from.
Without a hint from the logfiles everyone probably can only wildly guess around why you see this issue. 
Hi, it works now. But I did the workarround with sshfs.
Means, I mounted the ext. storeage with sshfs and then connect to it via ownCloud.
Directly connecting via SFTP didn´t work for me.
