BE ABSOLUTELY SURE THAT YOU ARE RUNNING THESE COMMANDS AGAINST THE CORRECT DRIVE.

These guidelines are very brief and require someone with Linux experience to execute correctly.
Introduction
After installing abd running DSpace for some time you realise your disk is getting full, so you arrange to buy a new bigger disk. But how do you use it in Dspace as a new asseststore. Read below for brief how-to.
Step 1
Determine the kernel hardware label for the new disk.
After connecting the new disk to the server and rebooting, login to the server using a console and type;
sudo fdisk -l
This command will list all the disks attached and the kernel label used.
Step 2
Create a linux partition on the new disk.
Assuming that you identified the new disk as /dev/sdb, from step 1 above, then type the following to create a single linux ext4 partition on the new disk;
sudo -i
parted /dev/sdb mklabel gpt
parted /dev/sdb mkpart primary ext4
parted /dev/sdb print
exit
Step 3
Make a linux filesystem on the new disk.
Step 2 above should have created a single primary linux partition on the disk.
Type the following to create an ext4 file system on the disk;
sudo mkfs.ext4 /dev/sdb1
Step 4
Make a mount point on the linux file system for the new disk.
Since the new disk will be used for an added asset store, we create the mount folder where DSpace was installed.
sudo mkdir /home/dspace/assetstore/two
Step 5
Mount the new disk to the mount point on the linux file system.
