How syncing host folders successfully?

[Francesco Zucca]

Hi at all

I'm in trouble with sharing-syncing  folders between host and guest in a Vagrant managed VM.

My env is made by

vboxmanage  --version 5.1.18r114002

vagrant --version Vagrant 1.8.6

vagrant plugin list

vagrant-share (1.1.6, system)

vagrant-sshfs (1.3.0)

vagrant-vbguest (0.13.0)

Host Ubuntu 14.04.5 LTS 64 bit

Guest   FEDORA 25 CLOUD --> https://atlas.hashicorp.com/fedora/boxes/25-cloud-base

I used this line in Vagrantfile for setup the folder syncing 

config.vm.synced_folder "/home/franzu/vagrant_data", "/vagrant_data"

Nothing in the message following the vagrant up, 

"==> default: Machine booted and ready!

[default] GuestAdditions 5.1.18 running --- OK.

==> default: Checking for guest additions in VM...

==> default: Rsyncing folder: /home/franzu/VirtualBox VMs/fedora25/ => /vagrant

==> default: Mounting shared folders...

    default: /vagrant_data => /home/franzu/vagrant_data

but I can't get any good result.  

The host and guest folders are not connected.

I googled a lot around, testing dozen of hints, but nothing helps me.

Any idea?  

TIA

best,

franz

hello

try with hashicorp/precise64

if that works, then is something on the VM.

not all the boxes have virtualbox additions installed, and try to use other means to sync ie nfs or rsync, that can explain.

from the guest can you provide the following outoput

sudo mount

thanks

Alvaro.

Hi Alvaro

as suggested I test  hashicorp/precise64

I tested it both with rsync  and  nfs,

as in following excerpt of Vagrantfile
config.vm.synced_folder "../data", "/vagrant_data", type: "nfs"

but unfortunately I can't sync anything.

Here instead the output of mount on precise 64

vagrant@precise64:~$ sudo mount
/dev/mapper/precise64-root on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
/dev/sda1 on /boot type ext2 (rw)
rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw)

Any hints?

thank

Hello

Please share a Vagrantfile where I can see the nfs and other for the rsync please so I can copy paste and test.

for the hashicorp/precise64 please provide this output on any (or both?) of the test.

vagrant destroy

export VAGRANT_LOG=debug

vagrant up

and share the generated output over a gist in github (gist.github.com)

thanks!

Alvaro

Hello.

From the logs

on the rsync seems is not working due the path you are using

try to sync a folder to /home/vagrant/data as a test

this is what rsync is doing:

"/home/franzu/VirtualBox VMs/data/", "vag...@127.0.0.1:/home/vagrant"

so is overwriting and deleting /home/vagrant

this is wrong:

{:type=>:rsync, :guestpath=>"/home/vagrant", :hostpath=>"/home/franzu/VirtualBox VMs/data",

For the NFS the path is right in the configuration but something is stopping to be shared:
 * Exporting directories for NFS kernel daemon...
exportfs: /home/franzu/VirtualBox VMs/data does not support NFS export

Try to share a different path, one that doesn't have spaces for example. NFS is a old protocol and have some limitations.

here some generic info based on my test using your Vagrantfile:

want to share that this works for nfs:

0 kikitux ~/Downloads/z (master) $ vagrant ssh -c 'mount -t nfs'

192.168.56.1:/Users/kikitux/Downloads/z/data on /vagrant_data type nfs (rw,vers=3,udp,addr=192.168.56.1)

Connection to 127.0.0.1 closed.

0 kikitux ~/Downloads/z (master) $ cat Vagrantfile 

  Vagrant.configure("2") do |config|

  config.vm.box = "hashicorp/precise64"

  config.vm.network "private_network", ip: "192.168.56.13"

  config.vm.synced_folder "data", "/vagrant_data", type: "nfs"

  config.vm.provider "virtualbox" do |vb|

    vb.memory = "1024"

  end

end

0 kikitux ~/Downloads/z (master) $ 

Tested on macOS

NFS from host to guest, requires the host is linux or macos and the guest is linux

rsync:

==> default: Configuring and enabling network interfaces...

==> default: Rsyncing folder: /Users/kikitux/Downloads/z/data/ => /vagrant_data

==> default: Mounting shared folders...

    default: /vagrant => /Users/kikitux/Downloads/z

0 kikitux ~/Downloads/z (master) $ cat Vagrantfile 

  Vagrant.configure("2") do |config|

  config.vm.box = "hashicorp/precise64"

  config.vm.network "private_network", ip: "192.168.56.13"

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

  config.vm.provider "virtualbox" do |vb|

    vb.memory = "1024"

  end

end

0 kikitux ~/Downloads/z (master) $ 

rsync required, rsync and ssh be installed on the host (ideally macos or linux) for windows the best is run vagrant from inside some environment where ssh and rsync are available

checking the gist now.

you are on a old vagrant please try to upgrade to latest version 1.9.3

Alvaro.
