Mounting the NFS Server to the RSS

This section describes mounting the NFS server to the RSS.

Set Up the Server

The following is an example of a server setup. Depending on your needs, your configuration may differ slightly. For more information, contact your Oracle representative. For information on configuring Oracle Linux, see Oracle Linux Administrator's Guide.

yum install nfs-utils
yum install lsof 
Note: Ensure a writeable folder exists to share.
 vi /etc/exports
<local>/<folder> 10.138.217.0/24(rw,no_root_squash)
- no_root_squash allows root user to write without it getting converted to nfsnobody user/group
systemctl start nfs-server
systemctl enable nfs-server
vi /etc/idmapd.conf
Domain = <domain> 
firewall-cmd --zone=public --add-service=nfs
firewall-cmd --permanent --zone=public --add-service=nfs
vi /etc/sysconfig/nfs 
# Port rpc.statd should listen on.
STATD_PORT=662
# Port rpc.mountd should listen on.
MOUNTD_PORT=892
vi /etc/sysctl.conf
fs.nfs.nlm_tcpport = 32803
fs.nfs.nlm_udpport = 32769

check no return for:
lsof -i tcp:32803
lsof -i udp:32769
lsof -i :892
lsof -i :662
systemctl reboot 
systemctl restart firewalld
firewall-cmd --zone=public --add-port=2049/tcp --add-port=2049/udp --add-port=111/tcp --add-port=111/udp --add-port=32803/tcp --add-port=32769/udp --add-port=892/tcp --add-port=892/udp --add-port=662/tcp --add-port=662/udp
firewall-cmd --permanent --zone=public --add-port=2049/tcp --add-port=2049/udp --add-port=111/tcp --add-port=111/udp --add-port=32803/tcp --add-port=32769/udp --add-port=892/tcp --add-port=892/udp --add-port=662/tcp --add-port=662/udp
16 .Verify the share is available (can be done from localhost, better to do from a non-RSS remote host):
$ showmount -e <nas_ip>
Export list for <client_ip>:
/home/nfs_share <client_ip>/<prefix>,<e.g.10.10.248.102/24>

Set Up the RSS as the Client

This section describes configuring the RSS as the client. For information on configuring Oracle Linux, see Oracle Linux Administrator's Guide.

Execute the yum install nfs-utils command.
Ensure the local folder, /opt/isr/ArchivedRecordings, exists and mount the directory using the following command:
```
mount -t nfs -o rw,nosuid <NFS Server IP>:/home/shareDir /opt/isr/ArchivedRecordings
```
Execute the ls -ltr command to ensure the directory is mounted properly. The following is a successful example output.
```
drwxrwxrwx. 4 isr isr 83 Dec 2 00:51 ArchivedRecordings
```
Ensure the directory is a part of an ISR group.
```
  chown isr:isr /opt/isr/ArchivedRecordings
```
The ISR is now able to read and write files.

Troubleshooting the RSS on Oracle Linux

Unable to "showmount" when you execute the following command:
```
$ showmount 11.145.333.05
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)
```
This indicates a problem with the firewalld configuration.
Unable to write to share.
```
$ touch tmpshare/foo.txt
touch: cannot touch `tmpshare/foo.txt': Permission denied
```
This indicates an issue with the permissions. Change the mode and ownership of the share on the NFS server with the commands chmod and chown.
