Unmounting fails on macOS and rclone hangs

[ncw]

The next thing rclone does after that log is to exit

                        fs.Infof(nil, "Exiting...")
                        os.Exit(exitCode(sig))

So at this point things aren't under rclone's control.

If the process is unkillable that means it is stuck in the kernel.

This is all pointing towards a bug in osxfuse.

This is not reproducible on Linux

Did you try with cmount on linux?

You'll have to build rclone yourself from source with the command go build -tags cmount. You'll need the fuse development files installed too.

That will give you a new command rclone cmount which works exactly the same as rclone mount but uses the same code that is used on macOS and Windows.

By not being reproducible I mean there was no issue on Linux.

[ncw]

I'm unclear as to whether you tried it with rclone mount or rclone cmount on Linux. To be testing the same code it will need to be tested with rclone cmount as rclone mount uses a different library on Linux.

I was using rclone mount, but both rclone mount and rclone cmount work.

I also tested both with invalid S3 credentials:

mkdir cmount
./rclone cmount aws-test: cmount
...
^C2024/04/10 18:11:22 ERROR : cmount: Unmounted rclone mount

mkdir mount
./rclone mount aws-test: mount
...
^C2024/04/10 18:11:59 ERROR : mount: Unmounted rclone mount

The directory disappeared from Files and this is the result of ls -l:

d?????????  ? ?    ?            ?            ? cmount
