Erro do Vagrant: NFS está relatando que seu arquivo de exportação é inválido

Estou tentando configurar o ambiente de desenvolvimento do Discourse usando essas instruções . No entanto, quando executo o Vagrant, recebo o erro:

NFS está relatando que seu arquivo de exportação é inválido. O Vagrant faz essa verificação antes de fazer qualquer alteração no arquivo. Corrija os problemas abaixo e execute "vagrant reload":

Não é possível abrir / etc / exports

Verifiquei e não tenho uma pasta etc / exports, então criei uma e executei vagrant reload. Isso me pegou:

Estou em um Mac (OS X 10.6.8). Como faço para corrigir isso? Tentei pesquisar a mensagem de erro original e tudo que encontrei foram alguns repositórios contendo o código-fonte do Vagrant que a lança.

Tente usar as versões boas conhecidas do VirtualBox e do Vagrant anotadas no Discourse como seu primeiro aplicativo Rails :

• Vagrant 1.1.2
• VirtualBox 4.2.10

Eu estava tendo o mesmo problema no Mac (OS X 10.9 (Mavericks)), mas reverter para essas versões pareceu resolver isso para mim.

Eu tinha algumas imagens / caixas anteriores instaladas na minha instalação do VirtualBox, então já havia algumas entradas inválidas /etc/exports. Então eu tive que limpar aquele arquivo e reiniciar minha caixa Vagrant.

NFS is reporting that your exports file is invalid. Vagrant does
this check before making any changes to the file. Please correct
the issues below and execute "vagrant reload":

Aqui está o que fiz na minha máquina host:

sudo rm /etc/exports
sudo touch /etc/exports

vagrant halt
vagrant up --provision

Eu tive esse problema com o Vagrant 1.4.1 e o VirtualBox 4.3.6 no OS X 10.9 Mavericks (13A603). Consegui consertá-lo com um comando simples para criar o arquivo / etc / exports ausente. Execute-o no OS X, não no convidado, conforme apontado nos comentários abaixo.

$ sudo touch /etc/exports

Consegui então executar com sucesso vagrant up. Encontrei outro erro em que o Guest Additions não estava atualizado, mas resolvi esse problema instalando o plugin vagrant-vbguest.

$ vagrant plugin install vagrant-vbguest

e então um rápido vagrant reloade eu estava pronto e funcionando!

Para mim, esse erro começou a aparecer em um ambiente Vagrant funcional.

Eu havia renomeado o diretório de onde o Vagrant estava rodando. Para consertar, executei 'sudo vi / etc / exports' e fixei o nome do caminho para que apontasse para o meu diretório atual.

A mesma coisa aconteceu comigo. Copiei meu Vagrantfile de outro projeto e esqueci de alterar as configurações de NFS. Isso fez com que a VM atual montasse a pasta pai da VM da qual copiei o Vagrantfile original. Então eu fiz isso:

vagrant halt
vagrant up

Ainda tenho o mesmo erro. Então eu rastreei meu arquivo de exportação localizado em / etc / exports que se parece com isto:

# VAGRANT-BEGIN: 501 64e10d4d-342e-4f55-b69a-97edda35742f
"/Users/[username]/vagrant" 192.168.11.12 -alldirs -mapall=501:20
# VAGRANT-END: 501 64e10d4d-342e-4f55-b69a-97edda35742f

# VAGRANT-END: 501 3e2aabfd-ce63-441b-85a2-1b51e8beb863
# VAGRANT-BEGIN: 501 ff92e353-9f6d-48ee-9d76-e29b33f1dd60

# VAGRANT-END: 501 ff92e353-9f6d-48ee-9d76-e29b33f1dd60

Os dois últimos caminhos são iguais. Então, excluí as últimas três linhas e executei:

vagrant halt && vagrant up

Agora tudo parece estar funcionando bem.

OSX 10.11.1 Vagrant 1.7.4

Eu não queria passar pelo aborrecimento de rebaixar. Isso é o que eu fiz (ainda demorou um pouco, mas menos incômodo do que rebaixar o IMHO):

1. No VM Vagrantfile, para qualquer pasta sincronizada, desabilite o NFS

   config.vm.synced_folder ".", "/vagrant", nfs: false

2. / Etc / exports removido

   sudo mv /etc/exports ~/Desktop/exports

3. Reescrever / etc / exports

   vagrant up

4. Reative o NFS se você quiser / precisar habilitado em sua VM

   config.vm.synced_folder ".", "/vagrant", nfs: true

Basta executar os seguintes comandos:

sudo rm /etc/exports
sudo touch /etc/exports
vagrant reload

Você não usar vagrant up --provisionse você não tem certeza de que ele não vai sobrescrever o status atual do seu projeto.

No Ubuntu 12 host / Ubuntu 12 guest, o seguinte funcionou para mim com o Discourse :

nfs_setting = RUBY_PLATFORM =~ /darwin/ || RUBY_PLATFORM =~ /linux/
config.vm.synced_folder ".", "/vagrant", id: "vagrant-root", type: "nfs", nfs_udp: "true", nfs_version: "4", :nfs => nfs_setting

Observação: também tive que adicionar um endereço IP de host determinado pelo Vagrant e um endereço IP de convidado determinado pelo Vagrant às exceções do firewall.
