NFS Server¶

Your node can serve as NFS server. This guide is for RHEL8 and later. By default RHEL8 serves NFS3 und NFS4, whereas RHEL9 and later will serve only NFS4. Still NFS3 can be configured if required.

To enable the NFS server, set base::enable_nfs_server accordingly in Hiera:

base::enable_nfs_server: true

Exports¶

Then the exports go below nfs_server::exports:

  '/home/meg/dcbboot':
    clients:
      - hosts: '*'
        options: 'rw,sync,no_root_squash,no_subtree_check'
  '/export/swissfel_athos/raw/maloja-staff':
    options: 'fsid=1012'
    clients:
      - hosts: 'sf-export-1[2-3]-100g'
        options: 'rw,async,no_root_squash'

For each directory you want to export place its path as key to nfs_server::exports. Below you can set the global options in options and a list of client specific access restrictions and options below clients.

Possible client host definitions and options you find in exports(5).

Non-Standard NFS Server Configuration¶

If you wish non-standard configuration in /etc/nfs.conf, you may set it in Hiera with key nfs_server::nfs_conf:

nfs_server::nfs_conf:
  nfsd:
    udp: 'y'
    vers3: 'n'
    threads: 32

For more details see nfs.conf(5)

Kerberos¶

Kerberos support for the NFS server is configured automatically by Puppet.

Exporting from GPFS¶

If you want to export data backed on GPFS, please set

nfs_server::after_gpfs: true

to start the NFS server only after GPFS is ready.
