Puppet module for setting up nfs server and clients.
Storeconfigs is used for propogating export configs to clients.
Optional nfs4-support.
Puppetmaster must be configured to use storeconfigs. Clients need to support augeas.
Check Modulesfile for module dependencies
I have tested the module on lucid, precise, centos5 and centos6. Chances are good it will work on rhel and sles aswell.
This will export /data/folder on the server and automagically mount it on client.
node server {
include nfs::server
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 {
include nfs::client
Nfs::Client::Mount <<| |>>
}
node server1 {
include nfs::server
nfs::server::export{
'/data_folder':
ensure => 'mounted',
clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)'
# exports /homeexports and mounts them om /srv/home on the clients
'/homeexport':
ensure => 'mounted',
clients => '10.0.0.0/24(rw,insecure,async,root_squash)',
mount => '/srv/home'
}
node server2 {
include nfs::server
# ensure is passed to mount, which will make the client not mount it
# the directory automatically, just add it to fstab
nfs::server::export{
'/media_library':

nfstag => 'media'
clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)'
