Virtual TapeServer 8.4 Configuration Guide

Maintaining GFS for VTS | 207
Shutting down GFS
If you need to remove one server from the cluster, use the following procedure.
To shut down GFS on one server
1. Log in to the server.
2. Become root:
su -
3. Unmount GFS file systems:
umount -a -t gfs
4. Stop the ricci configuration service:
service ricci stop
5. Stop the GFS service:
service gfs stop
6. Stop the clustered LVM service:
service clvmd stop
7. Stop the cluster manager service:
service cman stop
8. Reboot VTS. If no errors are displayed, it is safe to reboot VTS now that the node has been
removed from the GFS cluster. After reboot, you may need to manually rejoin the cluster.
To shut down the cluster
The following steps describe how to shut down your entire cluster. If you shut down half of the
servers, you need to shut down the entire cluster down. GFS requires that you have a quorum of the
servers up for the cluster to function.
1. Make sure that tape devices are stopped on the host server.
2. On each server you want to shutdown, perform these steps:
a. Log in as root.
b. Stop GFS and the supporting services:
service gfs stop
service ricci stop
service cman stop
service clvmd stop
reboot
