Here is an example of the output. The bolded lines indicate partitions that are eligible for

configuration:

Filesystem Size Used Avail Use% Mounted on

/dev/cciss/c0d0p2 19G 6.7G 12G 38% /

/dev/cciss/c0d0p4 112G 338M 106G 1% /VAULT00

/dev/cciss/c0d0p1 99M 24M 70M 26% /boot

tmpfs 502M 0 502M 0% /dev/shm

/dev/cciss/c0d1p1 3.3T 535G 2.6T 17% /VAULT01

3. Use parted to display the current partition layout for all disks.

parted /dev/cciss/c0d1p1 print

Here is an example of the output:

Sector size (logical/physical): 512B/512B

Partition Table: loop

Changing vault storage

Before changing the vault configuration, consider the following recommendations:

• Do not resize any vault on the operating system partition(s) (c0d0p1, c0d0p2).

• The minimum partition size is 1TB.

• The maximum partition size is 5TB.

• All data on a partition that is resized will be lost.

Also, keep in mind that performance and system operations will be slow when vaults are at

maximum capacity.

To modify the configuration, complete these steps. You can perform this procedure multiple

times, if necessary.

1. Identify the partition to modify. This example will modify VAULT01 (c0d3p1).

2. Unmount the file system.

umount /VAULT01

3. Create partitions on the disk.

If the disk partition is less than 2TB in size, complete these steps:

a. Starting with the first recognized disk after the system disk, create the partition by

entering the following command:

fdisk /dev/cciss/c0d3p1

The fdisk command displays a : prompt.

b. Print the current partition table by entering the following command:
