The parameter is incorrect

[Cas]

You can use the ltconfig plugin to change these settings "disk_io_write_mode" and "disk_io_read_mode" to 0.

Alternatively you can download a fixed version of core.py and copy the file into relevant Deluge install folder. i.e. C:/Program Files/Deluge/deluge.egg/deluge/core (Don't worry that there will be no existing core.py file)

I'm also having this issue. It's not every torrent that I receive this error, but more and more lately, torrents in Deluge are failing with "The parameter is incorrect" errors. Would love if someone could look into this.

Can you clarify if you, like sylinen and I, are experiencing this specifically in conjunction with Windows Storage Spaces? Just want to make sure we've got a clear, consistent pattern.

Yes, am running on Windows 8.1, all storage of torrents from incomplete file location to completed files is performed on a Windows Storage Space drive.

My recent problems seem to be associated with multi-file torrents. If it's the video file and the nfo, that's not a problem. But when there's a sample file, or multiple video files, that's when I get the error. The error usually references one of the files as the problem. utorrent does not reproduce this error.

So did you try the fix...

[captainnapalm]

Just to confirm, is the fix to use ltconfig to set the following settings to "0"?

disk_io_write_mode
disk_io_read_mode

Is there any way to increase "read_cache_line_size" or "write_cache_line_size" to get around this issue?

[Cas]

Yes.

The cache is currently disabled...

Alternatively you can download a fixed version of core.py and copy the file into relevant Deluge install folder. i.e. C:/Program Files/Deluge/deluge.egg/deluge/core (Don't worry that there will be no existing core.py file)

Can confirm this worked on: Windows 8.1 Pro + Storage Spaces + Deluge 1.3.10 + Python 2.7

This fix is now in 1.3.11.

I was having this problem, and also using Storage Spaces.
I've just upgraded to 1.3.11 and it's been running fine for about 20 mins now so it looks like you've sorted this Cas, thanks

This fix is now in 1.3.11.

Thank you so much CAS!

now let me try the best torrent client interface wise I've ever seen!

Many thanks for the fix in 1.3.11, I was almost ready to revert back to my old client but I'm glad I stuck with it. Great job.
