WebDav, Synology, Sync needs 2 attempts

Help and Support

Hi all

Just tried my very first sync with rclone - it's working (all files are there), but for some reason, it requires 2 attempts to complete. I'm finding this worrying, so before I use it for my main syncing, does anybody know whats going on here? Target: Synology WebDav, User has read/write access.

/ # rclone sync /source synology:target --progress -vv

Thx

I suspect the webdav server is returing 403 when rclone tries to create a directory that already exists...

Can you run with -vv --dump headers and post the log to confirm?

Here is the log:

What can be done if it is what you expect?
thx

That is what is happening. Though it isn't consistent...

I'm not sure I want to ignore a 403 for an already created directory as 403 is an error which might legitimately be returned.

I think what needs to be done is use a directory cache in webdav to stop it trying to create the directories more than once.

That said, the error is harmless and the retry will fix it up so it maybe isn't urgent.
