NFS

Installs NFS utilities on RedHat/CentOS or Debian/Ubuntu.

Requirements

None.

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

nfs_exports: []

A list of exports which will be placed in the /etc/exports file. See Ubuntu's simple Network File System (NFS) guide for more info and examples. (Simple example: nfs_exports: { "/home/public *(rw,sync,no_root_squash)" }).

nfs_random_port: '63700'

nfs_random_ports:
  nfs_callback: "{{ (nfs_random_port | int + 0) }}"
  nfs_lockd: "{{ (nfs_random_port | int + 1) }}"
  nfs_mountd: "{{ (nfs_random_port | int + 2) }}"
  nfs_statd: "{{ (nfs_random_port | int + 3) }}"
  nfs_statd_bc: "{{ (nfs_random_port | int + 4) }}"

NFS uses 2 fixed ports (111 for portmap and 2049 for NFS). Additionally NFS opens 5 random ports to stablish the communication with the clients. This properties fix this ports so you can open them in the hosts firewall. The role uses by default 5 consecutive ports: 63700 to 63704.
