Manage NFS networking using the CLI

This page describes how to configure the NFS networking using the CLI.

Using the CLI, you can:

Configure the NFS global settings

NFSv4 and Kerberos require a persistent cluster-wide configuration filesystem for the protocol's internal operations.

Use the following command line to set the NFS configuration on the configuration filesystem:

weka nfs global-config set [--mountd-port mountd-port] [--lockmgr-port lockmgr-port] [--statmon-port statmon-port] [--notify-port notify-port] [--config-fs config-fs] [--default-supported-versions default-supported-versions] [--enable-auth-types enable-auth-types]

To support NFS file-locking, ensure the system meets the prerequisites outlined in NFS file-locking support.
For the default published ports, see the Required ports.

Parameters

Name Value Default

Name	Value	Default
`mountd-port`	Set the alternate port if the existing mountd service is not operating on the default published port. 0 means use the default published port.	`0`
`lockmgr-port`	Set the alternate port for the NFS lock manager used in NFSv3. 0 means use the default published port.	`0`
`statmon-port`	Set the alternate port for the NFS status monitor used in NFSv3. 0 means use the default published port.	`0`
`notify-port`	Set the alternate port for notification used in NFSv3. 0 means use the default published port.	`0`

`default-supported-versions`	Determines the default NFS version. Possible values: `v3` `v4` `v3,v4`	`v3`
`enable-auth-types`	A comma-separated list of authentication types that can be used when setting the NFS client permissions. Possible values: `none,sys,krb5,krb5i,krb5p`Example:`krb5,krb5i,krb5p`	Depends on Kerberos configuration: If not configured: `none,sys` If configured: `krb5`

Name	Value
`name`*	Interface group name.

Name Value

Name	Value
`name`*	Interface group name
`ips`*	Valid IP range

Configure the service mountd port

The mountd service receives requests from clients to mount to the NFS server. It is possible to set it explicitly rather than have it randomly selected on each server startup. This allows an easier setup of the firewalls to allow that port.

Use the following command lines to set and view the mountd configuration:

weka nfs global-config set --mountd-port <mountd-port>

weka nfs global-config show

Configure user group resolution

NFS-W can authenticate more than 16 user groups, but it requires the external resolution of the user's groups, which means associating users with their respective group-IDs outside of the NFS protocol.

Procedure

Configure interface groups:
- See Create interface groups.
Configure NFS client permissions:
- See Set the NFS client permissions.
Set up servers for group-IDs retrieval:
- Configure relevant servers to retrieve user group-IDs information. This task is specific to NFS-W and does not involve WEKA management. See the following procedure.

Set up the servers to retrieve user's group-IDs information

For the servers that are part of the interface group, set the servers to retrieve the user's group-IDs information in any method that is part of the environment.

You can also set the group resolution by joining the AD and Kerberos domains or using LDAP with a read-only user.

Configure the sssd on the server to serve as a group IDs provider. For example, you can configure the sssd directly using LDAP or as a proxy to a different nss group IDs provider.

Example: set sssd directly for nss services using LDAP with a read-only user

[sssd]
services = nss
config_file_version = 2
domains = LDAP

[domain/LDAP]
id_provider = ldap
ldap_uri = ldap://ldap.example.com
ldap_search_base = dc=example,dc=com

# The DN used to search the ldap directory with. 
ldap_default_bind_dn = cn=ro_admin,ou=groups,dc=example,dc=com

# The password of the bind DN.
ldap_default_authtok = password

If you use another method than the sssd but with a different provider, configure an sssd proxy on each relevant server. The proxy is used for the WEKA container to resolve the groups by any method defined on the server.

To configure sssd proxy on a server, use the following:

# install sssd
yum install sssd

# set up a proxy for WEKA in /etc/sssd/sssd.conf
[sssd]
services = nss
config_file_version = 2
domains = proxy_for_weka

[nss]
[domain/proxy_for_weka]
id_provider = proxy
auth_provider = none
 
# the name of the nss lib to be proxied, e.g., ldap, nis, winbind, vas4, etc.
proxy_lib_name = ldap

All users must be present and resolved in the method used in the sssd for the group's resolution. In the above example, using an LDAP-only provider, local users (such as a local root) absent in LDAP do not receive their groups resolved and are denied. For such users or applications, add the LDAP user.

Integrate the NFS and Kerberos service

Integrating the NFS and Kerberos service is critical to setting up a secure network communication process. This procedure involves defining the Key Distribution Center (KDC) details, administrative credentials, and other parameters to ensure a robust and secure authentication process.

Before you begin

Ensure a configuration filesystem is set. See Configure the NFS global settings.
Ensure the NFS cluster is configured and running. see Configure the NFS cluster level.
For Active Directory (AD) integration, obtain the required information from the AD administrator. (WEKA handles the generation of the keytab file.)
For MIT integration, ensure the following:
- Obtain the required information from the MIT Key Distribution Center (KDC) and OpenLDAP administrators.
- A pre-generated keytab file in format stored in an accessible location is required.

In all KDC and LDAP parameters, use the FQDN format. The hostname part of the FQDN is restricted to a maximum of 20 characters.

Set the Kerberos service

Command: weka nfs kerberos service setup

Use the following command to set up NFS Kerberos Service information:

weka nfs kerberos service setup <kdc-realm-name> <kdc-primary-server> <kdc-admin-server> [--kdc-secondary-server kdc-secondary-server][--force] [--restart]

Update Kerberos configuration during maintenance mode

Once the Kerberos integration with NFS is configured, there might be instances where the Kerberos setup is modified.

Changes to the Kerberos configuration in a production environment are rare. We recommend making any necessary updates during periods of low load from NFS clients, such as when the system are in maintenance mode. This approach helps to minimize potential disruptions to your operations.
