You can use Ansible to automate the configuration of NFS Client Settings

1. Mount an NFS File system, and configure in /etc/fstab

Use state: mounted

- name: Mount NFS Share nfs-server:/usr/local
  ansible.posix.mount:
      src: nfs-server:/usr_local
      path: /usr/local
      fstype: nfs
      opts: rw,nconnect=16,nfsvers=3,tcp,hard,intr,timeo=600,retrans=2,rsize=524288,wsize=524288
      state: mounted

2. Unmount an NFS File System, but not leave /etc/fstab unmodified

Use state: unmounted

- name: Mount NFS Share nfs-server:/usr/local
  ansible.posix.mount:
      src: nfs-server:/usr_local
      path: /usr/local
      fstype: nfs
      opts: rw,nconnect=16,nfsvers=3,tcp,hard,intr,timeo=600,retrans=2,rsize=524288,wsize=524288
      state: unmounted

3. Umount an NFS File System, and remove settings from /etc/fstab

Use state: absent

- name: Mount NFS Share nfs-server:/usr/local
  ansible.posix.mount:
      src: nfs-server:/usr_local
      path: /usr/local
      fstype: nfs
      opts: rw,nconnect=16,nfsvers=3,tcp,hard,intr,timeo=600,retrans=2,rsize=524288,wsize=524288
      state: absent

4. Remount an NFS System, without chaning /etc/fstab

Use state: remounted

- name: Mount NFS Share nfs-server:/usr/local
  ansible.posix.mount:
      src: nfs-server:/usr_local
      path: /usr/local
      fstype: nfs
      opts: rw,nconnect=16,nfsvers=3,tcp,hard,intr,timeo=600,retrans=2,rsize=524288,wsize=524288
      state: remount
