Virtual TapeServer 8.0 Supplemental Installation Guide

Installing GFS | 3
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 steps 1-7 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. 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.
If the vault will be less than 2TB in size, complete the following steps to partition the disk:
a. Enter the following command to partition the device.
fdisk /dev/sde
b. Enter n to add a new partition.
c. Enter p to specify the primary partition.
d. Enter 1 to specify the first partition.
e. Press ENTER to accept the defaults.
f. Enter w to save the configuration.
To confirm the configuration, enter the following command:
fdisk -l /dev/sde
Here is an example of the output:
Disk /dev/sde: 18.4 GB, 18413722112 bytes
255 heads, 63 sectors/track, 2238 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
