Rclone mount and rtorrent issue

Suspected Bug
1

What is the problem you are having with rclone?

Hi,
I use rclone mount with rtorrent to download files to a cloud storage.
But when I try to use it, all torrents I try when automatically in Pause.
My command is
rclone mount pC: /home/user/torrents/rtorrent/pC/ --allow-other --no-modtime

I have no problem to copy files to folder
cp test /home/user/torrents/rtorrent/pC/

I see that [Paradox55] had the same problem and it was solved.
But the version I use has the problem.

What is your rclone version (output from rclone version)

rclone v1.50.2

  • os/arch: linux/amd64
  • go version: go1.13.4

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Linux ubuntu 16.04 LTS

Which cloud storage system are you using? (eg Google Drive)

I use pCloud Drive. I also try to use crypt with no success.

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone mount pC: /home/user/torrents/rtorrent/pC/ --allow-other --no-modtime

A log from the command with the -vv flag (eg output from rclone -vv copy /tmp remote:tmp)

Try adding --vfs-cache-mode writes to your command line.

Thanks for your answer.

I had the same problem

It's still in Pause.

I guess this is the problem. The flags O_RDONLY and O_CREATE are a weird set of flags to use! This says open the file read only, but if it doesn't exist then create it.

I think rclone is handling that in a different way to other linux file systems as it comes up with

Probably because it has a read only file handle...

I had a grep through rtorrent's source and I couldn't see where it is doing that.

Can you try the latest version of rtorrent?

Can you strace rtorrent to see whether it is calling open with O_RDONLY|O_CREATE or whether that is being lost in translation somewhere?

Hi,

Finally, I use Deluge instead of rtorrent and it works with option --vfs-cache-mode writes.
deluged -v
deluged: 1.3.12
libtorrent: 1.0.7.0

Thanks for your help.
