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.
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.
Procedure
-
Create the NFS share. This example uses a share at
nfs.example.com:/Satellite/pulp
. Ensure this share provides the appropriate permissions to Satellite Server and itsapache
user. Stop Satellite services on your Satellite Server:
satellite-maintain service stop
# satellite-maintain service stop
Copy to Clipboard Copied! Ensure Satellite Server has the
nfs-utils
package installed:satellite-maintain packages install nfs-utils
# satellite-maintain packages install nfs-utils
Copy to Clipboard Copied! You need to copy the existing contents of
/var/lib/pulp
to the NFS share. First, mount the NFS share to a temporary location:mkdir /mnt/temp mount -o rw nfs.example.com:/Satellite/pulp /mnt/temp
# mkdir /mnt/temp # mount -o rw nfs.example.com:/Satellite/pulp /mnt/temp
Copy to Clipboard Copied! Copy the existing contents of
/var/lib/pulp
to the temporary location:cp -r /var/lib/pulp/* /mnt/temp/.
# cp -r /var/lib/pulp/* /mnt/temp/.
Copy to Clipboard Copied! -
Set the permissions for all files on the share to use the
pulp
user. Unmount the temporary storage location:
umount /mnt/temp
# umount /mnt/temp
Copy to Clipboard Copied! Remove the existing contents of
/var/lib/pulp
:rm -rf /var/lib/pulp/*
# rm -rf /var/lib/pulp/*
Copy to Clipboard Copied! Edit the
/etc/fstab
file and add the following line:nfs.example.com:/Satellite/pulp /var/lib/pulp nfs rw,hard,intr,context="system_u:object_r:pulpcore_var_lib_t:s0"
nfs.example.com:/Satellite/pulp /var/lib/pulp nfs rw,hard,intr,context="system_u:object_r:pulpcore_var_lib_t:s0"
Copy to Clipboard Copied! This makes the mount persistent across system reboots. Ensure to include the SELinux context.
Enable the mount:
mount -a
# mount -a
Copy to Clipboard Copied! Confirm the NFS share mounts to
var/lib/pulp
:df
# df Filesystem 1K-blocks Used Available Use% Mounted on ... nfs.example.com:/Satellite/pulp 309506048 58632800 235128224 20% /var/lib/pulp ...
Copy to Clipboard Copied! Also confirm that the existing content exists at the mount on
var/lib/pulp
:ls /var/lib/pulp
# ls /var/lib/pulp
Copy to Clipboard Copied! Start Satellite services on your Satellite Server:
satellite-maintain service start
# satellite-maintain service start
Copy to Clipboard Copied!
Satellite Server now uses the NFS share to store content. Run a content synchronization to ensure the NFS share works as expected. For more information, see Section 5.6, “Synchronizing Repositories”.
