##Overview
Github Master:
This module installs, configures and manages everything on NFS clients and servers.
This module is a complete refactor of the module haraldsk/nfs, because Harald Skoglund sadly is not maintaining his module actively anymore. It is stripped down to use only the class 'nfs' and parametrized to act as a server, client or both with the parameters 'server_enabled' and 'client_enabled'. It also has some dependencies on newer stdlib functions like 'difference'.
It supports the OS Families Ubuntu, Debian, Redhat, SUSE and Gentoo. It supports also Strict Variables, so if you pass all OS specific parameters correctly it should work on your preferred OS too. Feedback, bugreports, and feature requests are always welcome, visit https://github.com/derdanne/puppet-nfs or send me an email.
If you want to contribute, please do a fork on github, create a branch "feature name" with your features and do a pull request.
##Module Description
This module can be used to simply mount nfs shares on a client or to configure your nfs servers. It makes use of storeconfigs on the puppetmaster to get its resources. You can also easily use the create_resources function when you store your exports i.e. via hiera.
##Setup
This Module depends on puppetlabs-stdlib >= 4.5.0 and puppetlabs-concat >= 1.1.2. It is tested till Puppet Version 4.2.
This will export /data/folder on the server and automagically mount it on client.
node server {
class { '::nfs':
server_enabled => true
}
nfs::server::export{ '/data_folder':
ensure => 'mounted',
clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)'
}
# By default, mounts are mounted in the same folder on the clients as
# they were exported from on the server
node client {
class { '::nfs':
client_enabled => true,
}
Nfs::Client::Mount <<| |>>
}
This will mount /data on client in /share/data.

##Limitations
##Contributing
Derdanne modules are open projects. So if you want to make this module even better, you can contribute to this module on Github.
This module based on Harald Skoglund haraldsk@redpill-linpro.com from https://github.com/haraldsk/puppet-module-nfs/ but has been fundementally refactored
