Using rsync on windows with vagrant running a Core

问题:

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

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

From my testing, if you are using cygwin, use the solution by @osroot25 .

If you are using cwRsync and do not have cygwin, there is no workaround using Vagrant except editing the source code as @Andrew Myers details. Tested using Vagrant v1.6.5.

My workaround that works for me is to bypass Vagrant altogether and use cwRsync directly. This works for me because I am syncing a folder that hardly ever changes. I might change it quite a few times in one day (so I have to remember step 2 below each time), but I then go weeks (or months) without any changes. Remember that to use cwRsync you have to edit and use the cwrsync.cmd script. Attempting to access the rsync.exe command directly or by adding it to your path will fail. Step 1: I added the following line to the end of cwrsync.cmd (in the installed folder):

rsync -re "ssh -p 2222" /cygdrive/b/VCS/packages/ vagrant@localhost:packages --exclude ".git/"

Step 2: I have a separate cmd window open that I run the cwrsync.cmd using the full path. Then if I need to sync changes onto the VM, I activate that window, up-arrow, return and updating is instant!

Modifying ENV to set cygwin fix by @osroot25 doesn't work with cwRsync because when you force cygwin detection, the "vagrant ssh" command will not work because it requires the cygpath command in cygwin, which you won't have, so you cannot ssh into the VM. Well you can if you use the ssh command directly with all the right options.

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

回答3:

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

回答4:

There is a hacky way to fix this (worked for me anyway) where you have to change

hostpath = Vagrant::Util::Platform.cygwin_path(hostpath)

to

hostpath = "/cygdrive" + Vagrant::Util::Platform.cygwin_path(hostpath)

on line 43 in C:\HashiCorp\Vagrant\embedded\gems\gems\vagrant-[VERSION]\plugins\synced_folders\rsync\helper.rb

It's different for 1.5.x, you can read this thread here about it: https://github.com/mitchellh/vagrant/issues/3230

I will, however, be the first to admit that editing the core is far from ideal.
