2 Open the /etc/amd.conf configuration file in a text editor and change /net to /hosts. So the file
contains the following:
#DEFINE AN AMD MOUNT POINT
[ /hosts ]
3 Save and close the file then restart the amd daemon: /etc/init.d/amd start
Configure the NFS and amd services to start automatically
By default, the NFS and amd services are set to start automatically on workstations and render nodes.
Perform the following procedure to check these services, and reconfigure their startup mode if necessary.
1 Log in as root to the workstation or render node. Open a terminal, and check that the amd and NFS
services are running by typing: chkconfig --list | egrep ‘nfs|amd’ The output of the command
should contain the following lines:
nfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off
amd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
2 If the services are not set to on for run levels 2 through 5, configure them to be started automatically
with:
chkconfig nfs on
chkconfig amd on
3 Reboot the workstation or render node for the changes to take effect.
Enabling Export Permissions
Edit the /etc/exports file on the Creative Finishing workstation so that render nodes on the background
processing network can access the media storage for the jobs submitted to Burn.
DescriptionDirectory
Enables remote access to clip libraries for Wire./usr/discreet/clip
Enables remote access to projects by Burn at start-up./usr/discreet/project
To edit the /etc/exports file:
1 As root, open for editing /etc/exports.
2 Enable access to the /usr/discreet directory on your workstation by appending to the file:
/usr/discreet *(rw,sync,no_root_squash)
This allows any remote system access to /usr/discreet. You can restrict access by adding the host
names for each render node to the line, separated by a colon (:). For example, to restrict access to the
/usr/discreet directory to nodes burn01 to burn03: /usr/discreet
burn01:burn02:burn03(rw,sync,no_root_squash)
3 Save and close the file then apply the changes with: /usr/sbin/exportfs -va
