Virtual TapeServer 8.4 Supplemental Installation Guide

Installing GFS | 13

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

Note that these commands also restart fencing and deactivate the cluster.

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. Verify that the volume is active:

ls /VAULT10

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

5. 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

6. Mount the vault by entering this command:

mount /dev/gfsvg1/gfslv1 /VAULT10

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

service luci start

service luci restart
