Using rsync on windows with vagrant running a CoreOS VM

Question

I am using windows 8.1 Pro pc running vagrant and cygwin's rsync.

I am configuring as such:

config.vm.synced_folder "../sharedFolder", "/vagrant_data", type: "rsync"

And when I execute vagrant up I get the following error:

C:\dev\vagrantBoxes\coreOS>vagrant up
Bringing machine 'default' up with 'virtualbox' provider...

There was an error when attempting to rsync a synced folder.
Please inspect the error message below for more info.

I assume it is an issue with how it is changing the directory path to /c/dev rather than C:\dev

Answer 1

like I commented in the github-issue, following line in your Vagrantfile will most certainly fix your problem

ENV["VAGRANT_DETECTED_OS"] = ENV["VAGRANT_DETECTED_OS"].to_s + " cygwin"

since this is local in your Vagrantfile, the source-files can be kept untouched

Answer 2

workaround: just ln -s /cygdrive/c/ /c on cygwin terminal
