# 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)`](https://man7.org/linux/man-pages/man5/exports.5.html).
|
|
|
|
## 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)`](https://man7.org/linux/man-pages/man5/nfs.conf.5.html)
|
|
|
|
## 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.
