Not deleting files as there were IO errors, but no errors has been logged

Suspected Bug

What is the problem you are having with rclone?

The log of "rclone sync" shows some errors, but does not show the cause. I mounted the synced folder and compared it with WinMerge and can't see any differences, so the sync worked.

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

rclone v1.66.0

  • os/version: Microsoft Windows 10 Pro 22H2 (64 bit)
  • os/kernel: 10.0.19045.4170 (x86_64)
  • os/type: windows
  • os/arch: amd64
  • go/version: go1.22.1
  • go/linking: static
  • go/tags: cmount

Downloaded using rclone-current-windows-amd64.zip at 2024-03-25 because rclone-v1.66.0-windows-amd64.zip had some issues, which were fixed on master.

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

sftp

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

rclone sync D:\my-path backup-user1:/ --filter-from %APPDATA%\rclone\filter-user1.txt --progress --fast-list --transfers 2 --checkers 2 --log-file .\log-v.txt -v

The rclone config contents with secrets removed.

rclone.conf:

[webhost]
type = sftp
host = host.net
user = username
port = 23
pass = password
shell_type = unix
md5sum_command = none
sha1sum_command = none

[backup-user1]
type = crypt
remote = webhost:/backup/user1/
password = password1
password2 = password2

filter-user1.txt:

- /path1/
- /path2/

-> Filtering works fine.

A log from the command with the -vv flag

The log with -vv is 100 MB and has more than 300.000 lines. I can't post the content because the filenames have to be secret. But searching for "ERROR" finds exactly the same lines as shown in the "-v" output.

Output of "-v" (yes, that is all):

Looks to me like the following issue, fixed in the latest beta:

Thanks. The "rclone-current-windows-amd64.zip" is the current stable version, not the current version from master. Your current version from master is called "beta release".

So I downloaded the wrong file due the strange naming. Using the "beta relase" fixed the problem. Thanks.
