Input/output error occured when copy large file

What is the problem you are having with rclone?

I am using rclone to mount cloud drive through webadv of alist. When I ran command "rclone ls [cloudPath]" after mounting, it showed list and seemed normal. But no matter what kind of cloud drive I mounted, I couldn't copy any large file to my local storage. Even though I mounted my local nas, it still didn't work.

Run the command 'rclone version' and share the full output of the command.

rclone v1.68.2

  • os/version: unknown
  • os/kernel: 4.4.180+ (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.23.3
  • go/linking: static
  • go/tags: none

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

I am using 115 Drive, Aliyun Drive and as above I said before also my own Synology nas. I converted them all to webadv for rclone mounting. The fault depends on which cloud drive I use. When I use my nas and Aliyun, I can copy small files but copying large file log error message immediately. When it comes to 115, I can see copy progress in log when I copy large file such as .mp4 and .mkv. The speed in the progress is fast at the beginning,but slows down as time goes by and gradually it become to several bytes persecond. Finally, failure occurs and the log produce input/output error.

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

rclone mount alist:/115 /volume1/docker/auto_symlink/alist --use-mmap --umask 000 --allow-other --allow-non-empty --dir-cache-time 24h  --vfs-cache-mode full --buffer-size 512M --vfs-cache-max-size 100G --daemon

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.
