Incorrect Output during copyto retry

What is the problem you are having with rclone?

Transferred stats are incorrect when an upload fails, then retries.
Test Steps:
1 start copy to remote location
2 during transfer mod the file - e.g. touch
3 rclone copy fails
4 copy retries but the upload stats are incorrect
5 also rclone appears to stall for a period, e.g. in log nothing seems to be happening for 3-4 minutes
6 the copy is ultimately successful, but with the erroneous output it is not possible to track progress accurately

The copy is reporting 100% transfer when it is only partially copied
e.g. in the log below, a file of ~686Mi is being copied, and is modded at ~350Mi. The next stats say 100% Transferred and ETA of 0s, even though only 50% of the file is transferred. Then, after a pause of 3-4 minutes, the transfer restarts and is successful.

The issue seems to be related to how rclone deals with the interruption, and retry. It reports 100% transferred when it is not, and it also appears to stall for a period before restarting the transfer.

This is very intermittent - so it does not happen every time - maybe 1 out of 20-30 attempts to reproduce the error actually reproduce the error.

I have tried to ensure a file is not modified when transfer has started, so hopefully this is less likely to happen, but it still looks like a possible bug.

I will try to get the latest rclone version installed and try again.

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

IBMCOS

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

rclone -vv --stats=55s --s3-disable-checksum --stats-file-name-length=0 --low-level-retries=5 copyto <source-file> <destination>```

A lot of things have changed since your ancient rclone version.... There were 20+ versions released since then... tones of fixes and improvements

If you want to draw some meaningful conclusions please repeat your tests with the latest rclone version. Otherwise I do not think it is worth to even look at this - unless somebody is interested how some historical rclone version worked.

Thanks Kapitainsky,

I intend to try with a later version, but thought it worthwhile raising the topic.

Why? What's the value in raising topic that you maybe discovered a bug in some very old rclone version?:slight_smile: Before testing with the latest version?

Let's see what your new version tests show.
