php – NFS从Vagrant客户端挂起到OSX

我有一个Vagrant客户,我正在使用它在本地运行Symfony 2应用程序进行开发.一般来说这工作正常,但是,我经常发现进程锁定在’D’状态(等待I / O).

例如.我尝试运行我的单元测试：

./bin/phpunit -c app

任务启动,但永远不会退出.在进程列表中,我看到：

vagrant 3279 0.5 4.9 378440 101132 pts/0 D+ 02:43 0:03 php ./bin/phpunit -c app

任务是不可杀戮的.我需要重新启动Vagrant客户,让它再次恢复.这似乎主要发生在PHP命令行应用程序中(但它也是我执行的主要命令行任务,因此它可能不相关).

syslog报告挂起的任务：

要配置该框,我将使用以下方式共享本地文件夹：

config.vm.synced_folder “/my/local/path.dev”,“/var/www”,:nfs => true

Vagrant在OSX主机上创建以下/ etc / exports文件：

# VAGRANT-BEGIN: c7d0c56a-a126-46f5-a293-605bf554bc9a

我确保使用插件：guestrant添加的访客添加内容是最新的：vagrant-vbguest

我不知道如何调试这个.我很清楚这是guest虚拟机和Mac OSX主机之间的NFS问题.如果我使用NFS Manager在OSX上尝试启动NFS的调试日志记录,我会在OSX中遇到内核恐慌.

有没有其他人有类似的问题？任何有关前进道路的建议都将受到赞赏 – 因为每天多次为客人提供电力循环是不可行的.
