This is the root cause.

I think this is because you've included google photos in the combine which doesn't have server side move. Try removing it and see if it works?

Nick, yes, removing google photos resolved the problem, thank you.

Unfortunately the combine can only advertise the minimum support for all the backends, so if one doesn't support Move then the combine won't.

It might be possible to change this to if one supports Move then advertise it though.

This example config seems to work ok, and moves deleted files to Trash on local file system.
I'm not yet sure what will happens to files created at the root or outside the cloud-drives on mounted combines -- how does it affect the vfs-cache?

combine shouldn't let you create files in the root.

When mounted, combine does let me create/rename/delete files in the root, but not folder/directory.
Maybe it should be posted as a bug or linked-topic?

See the log (-vv) on creating file "zzzzzzzzzzzzz.txt", renaming to "xxxxxxxxxxxxxx.txt", and deleting.

I see what you mean. The VFS with --vfs-cache-mode writes or full will let you create the file in the root, but it can then never upload it.

This problem isn't unique to the combine backend - if you made a local backend with a directory you couldn't write to, you'd have the same problem.

I'm not sure how to solve this - in general you don't know if you can write to a directory until you try.

@ncw Nick, Is there a way to test-for/catch such ERROR when in remote roots (fail to copy/upload), prevent the file creation, and pass the ERROR message to the gui (file manager)? Similar to trying to create a folder at combine root? I'm not sure if such code should go in rclone or fusemount. If better to add it in fusemount, then maybe you can send them a request?

Alas, no.

The writeback of the file is asynchronous so the file manager isn't waiting for rclone's reply.

You could try setting --vfs-write-back 0 - that might report the error directly to the explorer.

  --vfs-write-back Duration                Time to writeback files after last use when using cache (default 5s)

Tried --vfs-write-back 0, no report to gui.
How does creating folder/dir work?
Dir.Mkdir fail is reported to gui, can file creation be made with a similar function in mounted combines (e.g. File.Mkfile)?

$ rclone mount 00_GDrives: ~/GDrives --vfs-cache-mode=writes --vfs-write-back=0
