Back to Upgrading Hardware

BE ABSOLUTELY SURE THAT YOU ARE RUNNING THESE COMMANDS AGAINST THE CORRECT DRIVE.
WE CANNOT ACCEPT RESPONSIBILITY FOR ANY DATA LOSS.

These guidelines are very brief and require someone with Linux experience to execute correctly.

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 partition on the new disk;

sudo -i

parted /dev/sdb mklabel gpt

parted /dev/sdb mkpart primary ext4

parted /dev/sdb print

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;

mkfs.ext4 /dev/sdb1

Step 4

Make a mount point on the linux file system for the new disk.

Step 5

Mount the new disk to the mount point on the linux file system.
