Virtual TapeServer 8.3 Supplemental Installation Guide

Installing GFS | 3
4. Install the GFS RPMs by entering the following command:
/media/cdrom/installGFS.bash
Ignore any warnings that may be displayed.
5. Unmount and eject the DVD:
umount /media/cdrom
eject
6. Enter the following commands to disable clustering services that are included with the GFS
but not used by VTS. Failure to disable these can cause the system to hang.
chkconfig openais off && service openais stop
chkconfig saslauthd off && service saslauthd stop
If any of these commands returns a failure, it is not an error. It indicates that the process was
not running.
7. GFS RPMs inadvertently remove SCSI target mode support. To address this and maintain
correctly functioning virtual tape drives (VTDs), run the following command:
/usr/local/tape/bin/mkinitrd.pl -f
The VTS server is rebooted after this completes.
8. Repeat these steps on each server (node) that will be included in the cluster.
Complete the next four steps (steps 9-12) on only one server (node) that will be included in the
cluster. It is recommended that you shutdown all nodes in the cluster other than the one used in
these steps. If you are creating multiple vaults, you must also complete steps 9-12 for each GFS file
system to be used for vault storage.
9. Choose your device(s) to be used for GFS. You can use the fdisk -l command to list devices and
note the partition information (/dev/sde, for example). If a partition is not listed, check
connections to storage. Or, the storage may need to be configured; refer to the storage
documentation for details.
In the commands and output below, /dev/sde is used as an example device.
VTS assumes an empty, unpartitioned disk, and further disk partitioning is not performed.
Cluster members will mount devices based on LVM names, not SCSI device names, and these
GFS devices will not use disk labels.
