Virtual TapeServer 6.04.01 Installation Guide

Installing GFS | 35

Complete the next four steps (steps 8-11) 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

8-11 for each

GFS file system to be used for vault storage.

8. 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

Device Boot Start End Blocks Id System

/dev/sde1 1 2238 17976703+ 83 Linux

If the vault will be 2-4TB in size, complete these steps to partition the disk:

a. Start the partition editor, which is an interactive program similar to fdisk:

parted /dev/sda

b. Create a GPT disk label, which is a GUID partition table:

mklabel gpt

c. Create a 4TB primary partition at the beginning of the disk:

mkpart primary 0 4000G

Note that you can specify 100% instead of 4000G to create a partition that uses the

entire disk.

d. Quit parted.

quit

9. Perform LVM initialization of the device. /dev/sde1 is used as an example partition on

the /dev/sde device.

a. Create the physical volume by entering the following command:

pvcreate /dev/sde1
