linux - 在同一台服务器上安装多个 NFS 的 puppet

Question

我在同一台服务器上有几个 NFS 挂载点，但目录不同。例如:

    x.x.x.x:/stats   /data/stats
    x.x.x.x:/scratch   /data/scratch
    x.x.x.x:/ops   /data/ops    

但是当我尝试运行 puppet 时，它会在我的 fstab 中添加以下内容。 (错误的挂载分配)

x.x.x.x:/scratch   /data/stats       nfs     defaults,nodev,nosharecache     0       0
x.x.x.x:/scratch   /data/ops  nfs     defaults,nodev,nosharecache     0       0
x.x.x.x:/scratch   /data/scratch     nfs     defaults,nodev,nosharecache     0       0

它在所有挂载的分区上使用最后一个挂载选项。所以我做了一些研究并发现了以下错误。

然后添加了 nosharecache 选项，但仍然没有运气。这是我的 puppet 代码

class profile::mounts::stats {
  # Hiera lookups
  $location = hiera('profile::mounts::stats::location')
  $location2 = hiera('profile::mounts::stats::location2')
   tag        'new_mount'

 file { '/data/stats':
ensure  => directory,
owner   => 'root',
group   => 'root',
mode    => '0755',
require => File['/data'],
tag     => 'new_mount',
}

  mount { '/data/stats':
ensure  => mounted,
fstype  => 'nfs',
device  => $location,
options => 'defaults,nodev,nosharecache',
require => File['/data/stats'],
tag     => 'new_mount'
}



file { '/data/ops':
  ensure  => directory,
  owner   => 'root',
  group   => 'mail',
  mode    => '0775',
  require => File['/data'],
  tag     => 'new_mount',
}

 mount { '/data/ops':
ensure  => mounted,
fstype  => 'nfs',
device  => $location2,
options => 'defaults,nodev,nosharecache',
require => File['/data/ops'],
tag     => 'new_mount',
}

file { '/data/scratch':
ensure  => directory,
owner   => 'root',
group   => 'mail',
mode    => '0775',
require => File['/data'],
tag     => 'new_mount',
}

 mount { '/data/scratch':
ensure  => mounted,
fstype  => 'nfs',
device  => $location2,
options => 'defaults,nodev,nosharecache',
require => File['/data/scratch'],
tag     => 'new_mount',
}

 }

 }

我的hieara查询如下

profile::mounts::stats::location: x.x.x.x:/stats
profile::mounts::stats::location2: x.x.x.x:/scratch

为什么会导致一些意外行为？

Answer 1

我编译了这段代码，发现了一些问题:

您没有包含 File['/data'] 资源，但我假设您在其他地方有它？

编译后我在目录中看到了这个:

$ cat myclass.json | jq '.resources | .[] | select(.type == "Mount") | [.title, .parameters]'
[
  "/data/stats",
  {
    "ensure": "mounted",
    "fstype": "nfs",
    "device": "x.x.x.x:/stats",
    "options": "defaults,nodev,nosharecache",
    "require": "File[/data/stats]",
    "tag": "new_mount"
  }
]
[
  "/data/ops",
  {
    "ensure": "mounted",
    "fstype": "nfs",
    "device": "x.x.x.x:/scratch",
    "options": "defaults,nodev,nosharecache",
    "require": "File[/data/ops]",
    "tag": "new_mount"
  }
]
[
  "/data/scratch",
  {
    "ensure": "mounted",
    "fstype": "nfs",
    "device": "x.x.x.x:/scratch",
    "options": "defaults,nodev,nosharecache",
    "require": "File[/data/scratch]",
    "tag": "new_mount"
  }
]

因此，您同时将 /data/ops 和 /data/scratch 安装在 $location2 上。这是疏忽吗？它与您所说的要实现的目标不符。

否则我无法重现你所说的你正在观察的内容。

除了 Puppet 之外，还有其他任何东西在编辑 fstab 文件吗？您是否在新盒子上尝试过此代码？
