Appendix A. Using an NFS Share for Content Storage

Your environment requires adequate hard disk space to fulfill content storage. In some situations, it is useful to use an NFS share to store this content. This appendix shows how to mount the NFS share on your Satellite Server’s content management component.

Important

Do not mount the full /var/lib/pulp on an NFS share. Parts of the Satellite Server use transient SQLite databases, which have issues over NFS. Red Hat recommends the use of high-bandwidth, low-latency storage for the /var/lib/pulp file system. Red Hat Satellite has many operations that are IO-intensive so usage of high-latency, low-bandwidth storage could potentially have issues with performance degradation. Only use the NFS share for the /var/lib/pulp/content directory.

Create the NFS share. This example uses a share at nfs.example.com:/satellite/content. Make sure this share provides the appropriate permissions to the Satellite Server and its apache user.
Shutdown the Satellite services on the Satellite host:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
katello-service stop
```
```
# katello-service stop
```
Make sure the Satellite Server has the nfs-utils package installed:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
yum install nfs-utils
```
```
# yum install nfs-utils
```
You need to copy the existing contents of /var/lib/pulp/content to the NFS share. First, mount the NFS share to a temporary location:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mkdir /mnt/temp
mount -o rw nfs.example.com:/satellite/content /mnt/temp
```
```
# mkdir /mnt/temp
# mount -o rw nfs.example.com:/satellite/content /mnt/temp
```
Copy the existing contents of /var/lib/pulp/content to the temporary location:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
cp -r /var/lib/pulp/content/* /mnt/temp/.
```
```
# cp -r /var/lib/pulp/content/* /mnt/temp/.
```
Set the permissions for all files on the share to use the apache user. This ID of this user is usually 48.
Unmount the temporary storage location:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
umount /mnt/temp
```
```
# umount /mnt/temp
```
Remove the existing contents of /var/lib/pulp/content:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
rm -rf /var/lib/pulp/content/*
```
```
# rm -rf /var/lib/pulp/content/*
```

Edit the /etc/fstab file and add the following line:

Copy to Clipboard Toggle word wrap

nfs.example.com:/satellite/content    /var/lib/pulp/content   nfs    rw,hard,intr,context="system_u:object_r:httpd_sys_rw_content_t:s0"

nfs.example.com:/satellite/content    /var/lib/pulp/content   nfs    rw,hard,intr,context="system_u:object_r:httpd_sys_rw_content_t:s0"

This makes the mount persistent across system reboots. Make sure to include the SELinux context.

Enable the mount:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
mount -a
```
```
# mount -a
```
Confirm the NFS share mounts to var/lib/pulp/content:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
df
```
```
# df
Filesystem                         1K-blocks     Used Available Use% Mounted on
...
nfs.example.com:/satellite/content 309506048 58632800 235128224  20% /var/lib/pulp/content
...
```
Also confirm that the existing content exists at the mount on var/lib/pulp/content:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
ls /var/lib/pulp/content
```
```
# ls /var/lib/pulp/content
```
Start the Satellite services on the Satellite host:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
```
katello-service start
```
```
# katello-service start
```

The Satellite Server now uses the NFS share to store content. Run a content synchronization (see Section 4.3, “Synchronizing Content”) to make sure the NFS share works as expected.
