Virtual TapeServer 6.04.01 Installation Guide

38 | Installing GFS

11. Start ricci and luci.

For more information about these GFS services, refer to http://www.redhat.com/docs/

manuals/enterprise/RHEL-5-manual/en-US/RHEL510/Cluster_Administration/s1-start-

luci-ricci-conga-CA.html.

These services must be configured in the cluster before you can mount the newly created

GFS volume. Complete the following steps to start the services.

a. Make sure that the luci system has a proper /etc/hosts file. Here is an example

command to confirm the contents of the file:

cat /etc/hosts

Here is an example of the file:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.80.2 vtsdev27.commstor.crossroads.com vtsdev27

The file should list all cluster nodes. The localhost entry is for the system you are

using and the other entries are for the cluster nodes.

b. On each node, start ricci:

chkconfig ricci on

service ricci start

To confirm that ricci is running, enter the following:

service ricci status

c. On one (and only one) of the cluster servers, configure and start the luci service. Red

Hat recommends configuring luci on a non-cluster node. It will function properly on a

cluster node, though web connectivity is lost while the system is rebooting. If the luci

node goes down, the cluster cannot be administered with luci.

luci_admin init

When prompted, enter a new password.

Then, restart the luci service:

service luci restart

Note the URL given in the output; you will access it in the next step.

d. Configure the cluster using the luci web interface:

• Access the web interface by loading the URL given in the previous step in a web

browser.

• When prompted, accept the certificate permanently.

•Click OK if a certificate domain mismatch warning is displayed.

• Log in by entering the luci admin username and password.

•Click Add a System.

• Enter the fully qualified domain name of the GFS system.

• Enter the root password for that system.

•Click Add another entry.
