Configuring the ACSLSHA NFS Server

Perform the following steps to configure the NFS server:

Build a network bond between two NIC ports for load balancing and redundancy (see Figure 2-1).

# nmcli device status

DEVICE     TYPE     STATE     CONNECTION
eno1 ethernet connected eno1
eno2 ethernet disconnected --
eno3 ethernet disconnected --
eno4 ethernet disconnected --

# nmcli connection add type bond con-name bond1NFSSrv ifname bond1NFSSrv mode blance-rr ip4 10.0.0.45/24 autoconnect yes

# nmcli connection add type bond-slave con-name bond1NFSSrv-con1 ifname eno3 master bond1NFSSrv

# nmcli connection add type bond-slave con-name bond1NFSSrv-con2 ifname eno4 master bond1NFSSrv

# nmcli connection up bond1NFSSrv
# systemctl restart network
# nmcli device status

DEVICE       TYPE     STATE         ONNECTION
bond1NFSSrv  bond     connected     bond1NFSSrv
eno1         ethernet connected     eno1
eno2         ethernet disconnected  --
eno3         ethernet connected     bond1NFSSrv-con1
eno4         ethernet connected     bond1NFSSrv-con2

Create ACSLS user IDs and groups according to the instructions provided in the ACSLS Installation Guide.
ACSLS requires specific users and groups to be created as part of its installation. These users and groups are also required on the NFS Server. Refer to the ACSLS Installation Guide for instructions on how to create the required users and groups on the NFS Server. Ownership/permissions must be applied to the NFS share directory. In this example, the ownership/permission requirements must be applied to the /node1-node2-acslsha-share directory on the NFS server).
Install the nfs-utils package:
```
# yum install nfs-utils
```
Edit the /etc/exports file to define the directories that the server will make available for clients to mount. This directory will contain the ACSLS installation for both nodes. Each entry consists of the local path to the exported directory, followed by a list of clients (nodes 1 and 2) that can mount the directory with client-specific mount options in parentheses.
For example:
```
/node1-node2-acslsha-share 10.0.0.25(rw,sync,no_root_squash,no_all_squash)
/node1-node2-acslsha-share 10.0.0.35(rw,sync,no_root_squash,no_all_squash)
```
Note:
There is no space between a client specifier and the parenthesized list of options.

For more information, refer the exports(5) manual page.
Start the nfs-server service, and configure the service to start following a system reboot:
```
# systemctl start nfs-server
# systemctl enable nfs-server
```
Note:
It has been determined that using DNS in order to reference the IPs on both the NFS server and the local nodes can cause errors if DNS is not accessible or is excessively slow. Please use explicate IPs.
