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.
Do not mount the full /var/lib/pulp on an NFS share. Use high-bandwidth, low-latency storage for the /var/lib/pulp file system. Red Hat Satellite has many I/O-intensive operations; therefore, high-latency, low-bandwidth storage might 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. Ensure this share provides the appropriate permissions to Satellite Server and itsapacheuser. Stop the
satellite-maintainservices on the Satellite host:# satellite-maintain service stop
Ensure Satellite Server has the
nfs-utilspackage installed:# satellite-maintain packages install nfs-utils
You need to copy the existing contents of
/var/lib/pulp/contentto the NFS share. First, mount the NFS share to a temporary location:# mkdir /mnt/temp # mount -o rw nfs.example.com:/satellite/content /mnt/temp
Copy the existing contents of
/var/lib/pulp/contentto the temporary location:# cp -r /var/lib/pulp/content/* /mnt/temp/.
-
Set the permissions for all files on the share to use the
apacheuser. This ID of this user is usually 48. Unmount the temporary storage location:
# umount /mnt/temp
Remove the existing contents of
/var/lib/pulp/content:# rm -rf /var/lib/pulp/content/*
Edit the
/etc/fstabfile and add the following line: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. Ensure to include the SELinux context.
Enable the mount:
# mount -a
Confirm the NFS share mounts to
var/lib/pulp/content:# 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:# ls /var/lib/pulp/content
Start the
satellite-maintainservices on the Satellite host:# satellite-maintain service start
Satellite Server now uses the NFS share to store content. Run a content synchronization (see Section 5.2, “Content Synchronization Overview”) to ensure the NFS share works as expected.
