Puppet使用facter获取/分区文件系统类型

Question

我想确定/分区的文件系统类型。

facter mountpoints显示：

/home => {
  available => "1.81 GiB",
  available_bytes => 1946107904,
  capacity => "2.01%",
  device => "/dev/sda/home",
  filesystem => "xfs",
  options => [
    "rw",
    "relatime",
    "attr2",
    "inode64",
    "noquota"
  ],
  size => "1.85 GiB",
  size_bytes => 1986002944,
  used => "38.05 MiB",
  used_bytes => 39895040
},

我只想要文件系统类型（如xfs，ext2等）

哈希访问应该是什么样的？

Answer 1

要访问哈希值，请使用$hash_name['key name']，因此请使用$facts，访问mountpoints密钥，然后访问/密钥，再访问filesystem按键顺序：

$root_filesystem = $facts['mountpoints']['/']['filesystem']
