NFS

Description

Installs and configures NFS client, or server components

Requirements

Should work on any Red Hat-family or Debian-family Linux distribution.

Attributes

• nfs['packages']

  • Makes a best effort to choose NFS client packages dependent on platform
  • NFS server package needs to be hardcoded for Debian/Ubuntu in the server recipe, or overridden in a role.

• nfs['service']

  • portmap - the portmap or rpcbind service depending on platform
  • lock - the statd or nfslock service depending on platform
  • server - the server component, nfs or nfs-kernel-server depending on platform

• nfs['config']

  • client_templates - templates to iterate through on client systems, chosen by platform
  • server_template - server specific template, chosen by platform

• nfs['port']

  • ['statd'] = Listen port for statd, default 32765
  • ['statd_out'] = Outgoing port for statd, default 32766
  • ['mountd'] = Listen port for mountd, default 32767
  • ['lockd'] = Listen port for lockd, default 32768

• nfs['exports']

  • An array of strings to populate in an export file. Can be manipulated in recipes with the nfs_export LWRP.

Usage

To install the NFS components for a client system, simply add nfs to the run_list.

name "base"
description "Role applied to all systems"
run_list => [ "nfs" ]

Then in an nfs_server.rb role that is applied to NFS servers:

name "nfs_server"
description "Role applied to the system that should be an NFS server."
override_attributes(
  "nfs" => {
    "packages" => [ "portmap", "nfs-common", "nfs-kernel-server" ],
    "ports" => {
      "statd" => 32765,
      "statd_out" => 32766,
      "mountd" => 32767,
      "lockd" => 32768
    },
    "exports" => [
      "/exports 10.0.0.0/8(ro,sync,no_root_squash)"
    ]
  }
)
run_list => [ "nfs::server" ]

nfs_export LWRP Usage

Applications or other cookbooks can use the nfs_export LWRP to add exports:

nfs_export "/exports" do
  network '10.0.0.0/8'
  writeable false 
  sync true
  options ['no_root_squash']
end

The default parameters for the nfs_export LWRP are as follows

• directory

  • directory you wish to export
  • defaults to resource name

• network

  • a CIDR, IP address, or wildcard (*)
  • requires an option

• writeable

  • ro/rw export option
  • defaults to false

• sync

  • synchronous/asynchronous export option
  • defaults to true

• options

  • additional export options as an array, excluding the parameterized sync/async and ro/rw options
  • defaults to root_squash

nfs::undo recipe

Does your freshly kickstarted/preseeded system come with NFS, when you didn't ask for NFS? This recipe inspired by the annoyances cookbook, will run once to remove NFS from the system. Use a knife command to remove NFS components from your system like so.

knife run_list add  nfs::undo
