Troubleshooting

This section describes how to verify the installation and troubleshoot any issues.

1. Verify that the appropriate services are enabled and started by entering the following

commands:

chkconfig cman on && service cman restart

chkconfig clvmd on && service clvmd restart

chkconfig ricci on && service ricci restart

2. Verify that logical volumes cannot be seen by attempting to mount a logical volume

(/dev/gfsvg1/gfslv1 and VAULT10 are example values):

mount /dev/gfsvg1/gfslv1 /VAULT10

Here is an example of the output if the logical volume is not visible:

mount: special device /dev/gfsvg1/gfslv1 does not exist

3. Using the luci web interface, ensure that nodes are not fenced.

4. Enter the following command to activate all known volume groups in the system:

vgchange -ay

Here is an example of the output:

1 logical volume(s) in volume group "gfsvg1" now active

5. Mount the vault by entering this command:

mount /dev/gfsvg1/gfslv1 /VAULT10

6. If luci will not start or restart, enter the following:

service luci start

service luci restart

If luci can see a node but indicates that ricci is not running, but the node shows ricci is

running, output to the similar is displayed:

luci[15356]: Unable to establish an SSL connection to

192.168.80.2:11111: ricci's certificate is not trusted

Enter the following commands to remove luci:

rpm -e luci

rm -rf /var/lib/luci

You may need to reinstall luci or re-import the cluster. The luci RPM is available on the

GFS Install/Upgrade DVD. If necessary, mount the DVD and enter the following

command to install luci:

rpm -ivh /media/cdrom/vts-6.04-gfs-install/luci*.rpm

To review the cluster status, enter the following command:

cman_tool status
