Question

我有一个配方，可以在运行chef-client时创建/服务并安装它。但是，即使厨师已经创建并将其添加到fstab，也会挂载/服务。我以为厨师不会这样做。

#mkdir /service
directory node['storm-prep']['service']['dir'] do
  owner "root"
  group "root"
  mode 00755
  action :create
 recursive true
end

#Create /service
lvm_logical_volume node['storm-prep']['service']['name'] do
    group node['storm-prep']['volume-group']['name']
    size node['storm-prep']['service']['size']
    filesystem node['storm-prep']['filesystem']['type']
    mount_point #{node['storm-prep']['service']['dir']}
    action [:create]
end

#mount /service and add to fstab
mount node['storm-prep']['service']['dir'] do
    device node['storm-prep']['service']['device']
    fstype node['storm-prep']['filesystem']['type']
end

厨师 - 客户端错误结束

Answer 1

您可以使用所谓的guard：not_if。像这样：

mount node['storm-prep']['service']['dir'] do
    device node['storm-prep']['service']['device']
    fstype node['storm-prep']['filesystem']['type']
    # Don't execute the action if "/service" exists
    not_if "grep '/service' /etc/fstab"
end

Answer 2

修复

#Create /service

mount_point #{node['storm-prep']['service']['dir']}

需要

#Create /service

mount_point node['storm-prep']['service']['dir']

整个#mount部分可以删除

根本原因是LVM食谱中存在大量问题和错误代码

每次厨师 - 客户端运行时，厨师创建/服务
